Product Overview

The Square D by Schneider Electric QO 30 Amp Two-Pole Circuit Breaker is intended for overload and short-circuit protection of your electrical system. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR. All QO circuit breakers are equipped with the exclusive Visi-Trip indicator. When a QO Visi-Trip circuit breaker trips, the handle snaps to a midpoint position between "OFF" and "ON" and a highly visible, red indicator easily identifies the tripped breaker. This enables you to easily distinguish which breaker has tripped in a load center that may contain up to 42 different circuit breakers. QO circuit breakers have features no other manufacturer can offer. They come in many different sizes and can meet the needs of virtually every function in your home or business. These types of quality, industry exclusive products keep the Square D brand ahead of the competition and are builders' and electrical contractors' first choice in electrical protection.

circuit brakers

can I use a 30 amp where there is a 20 amp?
Asked by: shocked
Simple, no. You must use the breaker amp that matches the wire size you are using. If there is a 20A breaker in place and you replace it with a larger breaker then the wire size will not match and the breaker will not trip to prevent a fire.

How hot can this breaker get...I have 20amp running 12 to 18 hour at a time..

Asked by: Thefatmass
Hello, You would need to refer to the trip curves of the breaker. You may reference page 5 of document number 0100DB01401. Which is available on the internet. Regards, Customer Care Center

Customer Reviews

QO 30 Amp Two-Pole Circuit Breaker is rated 4.7 out of 5 by 6.
Rated 3 out of 5 by from Took Two Tries to Get a Good One Normally when you purchase something like this you don't really have any options. You have to match the breaker to your panel and so you're just buying the one that fits. Well I was pretty disappointed when I bought this because it immediately tripped when I turned on the new 30 amp 240v circuit I installed. It took me about 30 minutes of trouble shooting before I narrowed it down to the breaker itself and had to drive back to HD to get a replacement. The obvious indication was that even when not plugged in if you turned it on it would trip right away. So double check these before you walk out the store to save yourself an extra "trip"

Rated 5 out of 5 by from Professional Quality 30A Breaker Made the decision to use only Square D QO Series circuit breakers. Professional Quality! Robust design you can feel from the moment you pick one up. Firm "snap-in" style to the panel load bar. Large variety of amperage/voltage to fit all my needs. Securely holds the wire and allows for easy replacement with minimal effort. The trip window on the front of the breaker allows me to quickly identify a tripped breaker without need for test equipment.
