Description
Offering a specialized 30/40A split, the P3040 tandem breaker maximizes panel space by housing two distinct circuits in a single footprint. It retains the traditional push-button operation of the Pushmatic family. Designed to bolt into legacy ITE and Siemens Pushmatic load centers, this breaker restores functionality to older installations. It serves as an exact swap for failing components. With a 10kAIC rating at 120VAC, it provides essential overload and short-circuit protection.Specifications

Product FAQs
7 answersWhat panels are compatible with the P3040 circuit breaker?
This breaker is designed exclusively for legacy Pushmatic load centers. It features a bolt-on connection and will not fit standard plug-on panels or modern load centers.
How does the 30/40A rating function on this tandem breaker?
The tandem design provides two independent 120V circuits within a single mounting space. One circuit is rated for 30 amps and the second circuit is rated for 40 amps, allowing you to maximize space in older panels.
Can the P3040 be used to supply a 240V load?
No. This tandem breaker provides two independent 120V circuits and lacks a common trip mechanism. It is not suitable for 240V applications that require a true two-pole breaker.
What wire sizes are accepted by the terminals on this breaker?
The screw and clamp terminals are designed to accept wire gauges ranging from 14 AWG to 4 AWG. Always verify local electrical codes for proper wire sizing based on the independent 30A and 40A circuit ratings.
Is this breaker a direct replacement for older Bulldog or ITE Pushmatic breakers?
Yes. Pushmatic load centers and breakers were manufactured under the Bulldog, ITE, and Siemens brands. The P3040 is a direct replacement for legacy 30/40A Pushmatic tandem breakers across all these brands.
What is the proper installation method for the P3040 breaker?
The breaker must be bolted directly to the busbar in a Pushmatic load center. Because it is a bolt-on design, the panel must be completely de-energized before installation to prevent arc flash hazards.
How do you manually operate the P3040 breaker?
Like all Pushmatic breakers, the P3040 features a push-button operation rather than a traditional toggle switch to manually open or close the 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.

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.
