Asked by Sparky September 17, 2020

Answers

To respond to the Siemens answer. No, I have two single pole breakers that are both connected to a transfer switch. I want to know if I can use the whole house surge protector breaker to replace those two single-pole breakers. Or do I have to use breakers that are not connected to a transfer switch?

Asked by Vincent September 16, 2020

Answer

No, this cannot be done. Firstly, there is no handle tie available to make a common disconnect and, secondly, doing so would not make the poles common trip. Each pole services one leg of the load center and one 120V circuit. It is important that the poles operate independently so that if one fails there is still protection provided on the other leg.

Answer

If the LEDs are on at all (regardless of the intensity) then there is no reason to be believe surge protection is not being provided. However, we don't know the condition without examining the device. If you are concerned about the life expectancy our recommendation is to replace it. There is no benefit to installing both the old and new device together. Doing so will not increase the level of protection.

What is the Nominal Discharge Current rating? 10kA?

Asked by anon March 2, 2019

Answer

Yes, MSA2020SPDP has a discharge current withstand rating of 10kA line-to-neutral (not to be confused with the 10kA interrupting rating).This is listed on page 3-16 of the link below. https://w3.usa.siemens.com/powerdistribution/us/en/speedfax-product-catalog/Documents/2017/SF-17-Sect-03-ALL-web.pdf

Will this fit in a GE panel?

I think it will fit physically but it's not rated for a GE panel. GE makes whole house surge protector, however it doesn't have the built in breakers so you loose 2 full size spaces.DIYer

Asked by JayFootball July 12, 2018
1
Answer

Yes. MSA2020SPDP is a Type QP breaker. The designation of circuit breaker types changed in the late 1970’s when series ratings were introduced. Before that time ITE manufactured circuit breakers that were identified as EQ-P or EQ-T. In approximately 1976 these designations were changed to circuit Breaker Types QP and QT, respectively, by dropping the E. Types QP and QT can be used in equipment that have the earlier ITE Types designated on the interior label or marking of the equipment. For a formal letter stating this send a request to productselection.us@siemens.com.

My electrical panel is a Murray style MP. Will this fit?

The electrical box says: "Circuit Breakers use class CTL Murray Style MP, I.T.E. style EQ-P, or Westinghouse Quicklag P" It does not say MP-T style. Will this surge protected Circuit breaker fit?

I installed a replacement for the same model that was installed for about 20 years. Within 1 year it had oxidized (still seems to be working though). I called the manufacturer and they couldn't tell me what was causing it or if it was dangerous.

Response from SIEMENS Product ExpertFeb 12, 2018
Hello,
I am sorry to hear that. One factor could be the age and/or location of the equipment this was being used with. If it was exposed to the outdoors and not in the properly rated enclosure that could also be a potential factor. Our aftermarket tech support line is 800-333-7421 and we would be happy to research further into this SIEMENS
Best Circuit Breaker Style Whole House Surge Suppressor on the market
This is the best circuit breaker style plug in whole house surge suppressor on the market. The clamping voltage is 500V which is 100V lower than most other whole house surge suppressors. Most manufacturers try to explain that it is important to keep the leads, if any, as short as possible between the connection point on the electrical panel and the surge suppressor, but most manufacturers also fail to explain what will happen if you do not. There are no leads on circuit breaker style surge suppressors. Circuit breaker style surge suppressors are also called integral surge suppressors. See the picture below from a document called TVSS_wp1.pdf that I found on the internet. Compare the Green verticle bar for Probe #2 (surge voltage at the wall outlet) for an integral surge suppressor to the Yellow (3 feet of 6AWG connecting leads) and Blue (3 feet of 10AWG connecting leads). 3 feet of 6AWG connecting wire will double the surge voltage that gets past the surge suppressor and 3 feet of 10AWG connecting wire will let 2.5x more surge voltage get through to your appliance.
