Part of the classic Pushmatic line, this 30A, two-pole molded case circuit breaker provides reliable thermal-magnetic protection for residential and commercial systems. It is designed to replace aging units without requiring panel modifications. The bolt-on design mounts securely into vintage Pushmatic load centers, serving as an exact cross-reference for the UBIP230 and P230. Rated for 10kAIC at 120/240VAC, it features the signature push-button actuation that defines the series.
What load centers are compatible with the Siemens P4230?
The P4230 is designed specifically for vintage Pushmatic load centers. These panels were historically manufactured under the ITE, Bulldog, and Siemens brands.
What legacy part numbers does the P4230 replace?
This 30A, 2-pole breaker serves as a direct replacement for older P230 and UBIP230 Pushmatic circuit breakers.
How is the P4230 actuated?
Unlike standard toggle breakers, the P4230 features the signature push-button actuation characteristic of the Pushmatic series to manually open and close the circuit.
How does the trip mechanism function on the P4230?
The breaker uses fixed thermal-magnetic technology to deliver long-time overload protection and instantaneous short-circuit protection. The common trip function ensures both poles open simultaneously during a fault.
Does the P4230 require panel modifications for installation?
No, the bolt-on design is engineered to mount securely into existing Pushmatic load centers without requiring any modifications to the vintage panelboard.

Review summary
Customers rate this product 5.0 out of 5 based on 18 reviews.
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
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.

Happy 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.
