Product FAQs
7 answersWhat legacy brands does the Siemens P250 replace?
The Siemens P250 is a direct replacement for discontinued Pushmatic breakers originally manufactured by ITE, Bulldog, and Gould. It fits into the same vintage Pushmatic load centers and uses the identical P250 catalog number.
How does the P250 operate compared to standard circuit breakers?
As a Pushmatic breaker, the P250 utilizes a push-button mechanism instead of a traditional toggle switch. You press the button to manually engage or disengage the circuit, and the button position provides visual indication when the breaker trips.
How is the Siemens P250 secured inside the load center?
This breaker features a bolt-on mounting design. It fastens directly to the busbar in compatible ITE and Siemens Pushmatic panels using screws, which provides a secure and reliable connection for older infrastructure.
Does the P250 provide common-trip protection for 240V circuits?
Yes. This 2-pole breaker includes an internal common-trip mechanism. If a thermal overload or instantaneous short circuit is detected on either leg of the circuit, both poles trip simultaneously to completely disconnect power to the load.
What wire sizes are compatible with the P250 terminal lugs?
The load side lugs on this 50A breaker accept either copper or aluminum wiring ranging from 8 AWG to 4 AWG. Electricians must ensure the selected wire gauge meets local codes for a 50A circuit.
Can the P250 be installed in standard Siemens plug-on panels?
No. The P250 is exclusively designed for Pushmatic load centers. It will not fit in standard plug-on or modern bolt-on panels due to its unique physical footprint and push-button configuration.
What applications typically require a 50A 2-pole Pushmatic breaker?
A 50A 2-pole breaker is commonly used to protect heavy 240V residential or light commercial loads. Typical applications include electric ranges, large central air conditioning condensers, or feeding small subpanels in legacy Pushmatic systems.

- 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.

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.
