Product FAQs
5 answersWhich electrical panels are compatible with the Siemens P240 circuit breaker?
This breaker is designed exclusively for use in legacy ITE, Bulldog, and Siemens Pushmatic load centers. It will not fit standard plug-on or modern bolt-on panels from other manufacturers.
Can the Siemens P240 replace older ITE or Bulldog Pushmatic breakers?
Yes, the Siemens P240 is a direct replacement for legacy ITE and Bulldog Pushmatic 40-amp, 2-pole breakers, including those marked with catalog number 31240.
How does the Pushmatic mechanism operate compared to standard breakers?
Unlike traditional breakers that use a toggle switch, Pushmatic breakers feature a push-button actuation mechanism. You press the button to manually open or close the circuit, and a mechanical indicator shows whether the breaker is in the ON or OFF position.
How is the Siemens P240 installed into the load center?
The P240 utilizes a bolt-on connection. It must be securely fastened directly to the panel busbar using screws to ensure a proper and safe electrical connection, which is standard for the Pushmatic design.
What type of trip protection does the P240 offer?
It features thermal magnetic trip technology. The thermal element provides long-time protection against sustained overloads, while the magnetic element offers instantaneous protection against short circuits.

- GJGregg J.Verified BuyerReviewingSiemens PFP3 Filler PlateI recommend this productRated 5 out of 5 stars8/8/25Easy to order and Quick Shipping
I needed some filler plates for an older breaker panel. Not available at any retail places I could find, thankfully Superbreakers had them. A couple minor issues: they didn't include the size specifications (L x W x D) online, which would have helped confirm they were the right fit; and they included an unrelated picture (along with the right one).
But the online order processing was easy-to-use and had all the info needed (especially the shipping options/costs, and the return policy). They also stuck to their word about getting it out in 24 hours. It arrived via UPS Ground in a respectful 5 days. They of course fit the panel and all is well.
Overall, very pleased with the company.

The part was correct,, but I was shocked when the cheapest (ground) shipping was almost as much as the part that only weighed 8 ounces. The part was $14.03 and the shipping was almost $13.00.

- KDKurt D.ReviewingSiemens P120 - 20A 1 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars5/28/20Happy with my Purchase
This is the 4th time I have used SuperBreakers and have been happy with my purchase every time. I have an old style style system in my house and the company I was using told me the old style breakers were impossible to find and charged me $80 each. Next time I needed one I found SuperBreakers had them for $15 each. I am no longer using that electrical company.
