Product Overview

The Pumptrol FSG2J21M4CP electromechanical pressure switch by Square D is the most trusted brand in residential, commercial and industrial pumping applications. This switch has a 30 psi to 50 psi pressure setting range activates an electrically driven water pump within a power circuit when the adjustable rising and falling thresholds are reached. The NEMA 1 enclosure has a 1/4 in. NPSF internal fluid connection and screw clamp terminals. The switch works with a 1.5 HP or less pump. The adjustable differential range is 15 psi to 30 psi and the cut-out range is 20 psi to 65 psi. The low-pressure cut-off (auto-start-off) operates at approximately 10 psi below the cut-in and will turn off the pump. The enclosure is National Electrical Manufacturers Association (NEMA) Type 1 and Ingress Protection (IP) 20 rated. The switch is Underwriters Laboratory (UL) Listed and Canadian Standards Association (CSA) Certified. For over 75 years, Square D pressure switches continue to meet the needs of our customers. Square D Pumptrol pressure switches are manufactured by Schneider Electric.
  • If system pressure is lost for any reason, a low water condition for example, the automatic lower pressure/water cut-off feature will open the contacts, turning off the pump
  • Universally accepted and recognized design is easy to wire, features drift-proof cut-in and cut-out settings and has visible vertical contacts which are easy to inspect
  • Switch is UL Listed and CSA Certified
  • Activates an electrically driven water pump within a power circuit when the adjustable rising and falling thresholds are reached

The Square D pumptrol switch is honestly one of the most reliable components in the plumbing industry. They have been making this switch for decades for what must be hundreds of applications and they work great. It’s not unusual for me to inspect equipment that is 20, 30 years old and older with the original switch still working flawlessly. I got this switch as a backup in case mine fails. Power surges that are common in my area destroy electrical parts like these. The advantage of this switch is the manual “on” lever that requires the pump to be manually pressurized (by holding the switch lever on until pressure builds up) as a way to protect very expensive pumps and other equipment. If the water pressure gets too low, this indicates that there is not enough water to be pumped or there is a pump failure. Instead of ruining your pump by running it dry, or stressing your electrical system by powering a failed pump, this switch simply shuts off. In areas where stored water is used or power failures ate common, this switch is a life saver. I highly recommend it.

These things last forever but since I am rearranging the plumbing I figured I would replace the well pump switch as well. The old one is at least 15 years old and probably older. I decided on the Square D switch with the low pressure cut off since the well will be serving 2 buildings approximately 150 ft apart. If I had a catastrophic failure in the remote building, as soon as the pressure drops 10 psi below the minimum setpoint, the pump would be cut off. As the switch will be located inside the house, resetting the switch would be easy enough. We have never had an issue with our well going dry, but if you did, having the low pressure cut-off would prevent the switch from calling for water and burning up the pump. These are super simple devices and there is really only a couple of things that can go wrong with them. You can get carbon buildup on the contact points from switching on and off over a period of many years. This is easily remedied with some emery cloth or light filing. The other is using an inappropriate pressure tube between the switch and the well tank. You should use something that will not readily corrode. Steel or galvanized pipe will corrode and the corrosion will eventually block the pressure tube and prevent the switch from detecting changes in pressure. If you do decide on the pressure switch with the low pressure cut-off be aware there are 3 settings for the low pressure cut off. The first is Auto - this is where you will generally have the switch set - the pump will come on when the pressure in the well tank drops to the low pressure set point and the pump will turn off when the pressure in the well tank reaches the high pressure set point. There is an Off position - this can be triggered if pressure in the well tank drops 10 psi or more below the low pressure set-point or can be used to turn the switch off manually (be aware there is still power to the switch when it is in the off position - if you are working on the switch turn the power off at the breaker) From the Off position you will need to manually reset the switch. Finally there is the Start position. This is used when the pressure in the well tank is below the minimum set point and you want to turn on the well pump to get the pressure in the well tank above the minimum setpoint - after which you would return the the low pressure cut off to the auto setting. Square D is a name that I trust, these switches last forever and are very reasonably priced. What more can you ask?

Square D Pumptrol 30-50 psi Well Pump Water Pressure Switch with Low Pressure Cut-Off I needed to replace the pressure switch on my well. I have a 1 ½ HP pump in the well that fills a storage tank. A 30 to 50 PSI pressure switch on a 20 gallon pressure tank is plenty for that job. I replaced a Square D product that was at least 15 years old And exposed directly to the elements. The contacts were just not worth fooling with any longer. Square D has always been my go to product for the last 35 years. I can put it in and safely forget about it. Even in hard water. Easy to install. Company videos available should have the need to watch someone do it first. Easy to adjust if you need a little more pressure. The Low pressure cut off will save your pump and the manual restart you may have to implement is way less expensive than replacing the pump in the well. Another complete system provides higher pressure for the buildings on a 5 acre property. [I use a 40-60 Square D pressure switch for that.] This was made in North America. I get the best and save myself a lot of trouble down the line.

We have a deep well pump at our camp house in Ocala and the pressure switch was starting to malfunction and not work properly. Decided to replace it rather than keep fixing it so we purchased the SQUARE D PUMPTROL 30-50 PSI WELL PUMP WATER PRESSURE SWITCH WITH LOW PRESSURE CUT-OFF. This was almost an exact replacement to our original switch. Well built and simple to operate. Were able to install it with nearly no problems.

This is just what I needed to replace my old pressure switch that kept sticking. Square D seems to never fail for anything that I have used of theirs. I love the low pressure cut-off feature, as this is on a pump at a property we are not at all of the time. I have often wondered how fast it would burn up a motor if the water supply to the pump was interrupted and it just started running. Fortunately for us, it isn’t around anything that could catch on fire, but I still don’t want anything ruined. Also, the on/auto/off switch is a nice feature which will keep me out of the breaker box when we winterize everything. Installation is easy with this and I will suggest that you take a picture of the old switch before you remove it from your pump. That way, you won’t have any questions about the wiring when you install the new one. Everything comes with the switch that you will need for installation EXCEPT the small nipple on the back that goes into the pump. I made a couple of adjustments to get the pressure to the 50 psi cutoff which only takes a few minutes with an air gauge. It is a great replacement switch.

This was a replacement for my well pressure tank. When the water is low it turns on the pump in the well. When the water gets high in my well pressure tank it turns off the pump in well. As a replacement it is easy to install. First turn off the power to it. Take the lid off the old one and remove the wiring. then remove the unit. then put to new one in and turn the power on. Simple even for me.

This Square D Pumptrol 30 to 50 psi Well Pump Water Pressure Switch with low pressure cut-off is a very reliable and safe pump controller. I use this for my shallow well on the water pump in my basement. The older one I have is at least 30 years old or more. The reason I wanted to replace it is recently about once a year it will not turn on and I have cleaned the contacts which seemed to be slightly burnt. This new pump pressure switch has a few more features then my old one but it is still a direct replacement and only took about twenty minutes to install. It has a low pressure cut-off which is set about 10 pounds below the cut in pressure and will shut the pump off. There is a manual lever to power off the pump for maintenance or to start it after a low pressure cut-off (auto - start - off) The control is normally left in the auto position. There are a few different versions of this control with different pressures but the 30 to 50 psi one is the most common. The high and low pressures are adjustable and the instructions are very clearly written. I am sure I will get many years of reliable service from this Square D Pumptrol.

I've used PumpTrols for over 40 years. Why would anybody use anything else? They give long good service, more than your money's worth. In smaller households they last and last; in heavy service you still get a lot of water for your money. Look on your pressure-tank for the fill pressure. Mine says "30PSI" so this 30-50psi is a correct control. For most installations you want a "Low pressure cut-off" so if a pipe splits the pump does not run non-stop; with this to re-start the pump you hold the side-lever half-way until pressure comes up to 30psi.

Got this as replacement for the same square D shut off. Last one lasted about 6 years. It does it job and shuts down the pump when there's change in pressure, I had issues with a very leaky toilet and a outside faucet and this switch shutting down the well pump is what alerted me to the issue. It does trip maybe once a year for unknown reasons, its easy to remove the cover and reset and thats easier to deal with then replacing a burnt out pump.
