P120 - 20A Circuit Breaker

P120 - 20A Circuit Breaker

If you're replacing a P120 circuit breaker in an existing residential electrical system, getting the right fit matters just as much as matching the amp rating. This P120 is a new aftermarket breaker made to replace the original Pushmatic P120 in compatible applications. It's a 20-amp, 1-pole breaker with a Type P bolt-on design and a 10k A.I.C. rating at 120VAC. The breaker measures 1.5 inches high, 1 inch wide, and 2.81 inches deep, so it fits the space and mounting arrangement used by the original P120. It's a straightforward replacement for electricians and maintenance professionals working on legacy equipment where the existing configuration needs to stay the same. No unnecessary changes to the application—just the correct form, fit, and function for equipment that calls for a P120. It's also built to last when installed correctly and used within its stated electrical ratings.

Material Compliance and Certifications

The available specifications for this breaker don't include material compliance details or specific third-party certifications. Because electrical requirements can vary by equipment and location, don't assume a certification or listing that isn't documented.

Where It Works Best

This P120 20 amp breaker is meant for compatible legacy residential electrical equipment that already calls for the P120 configuration. It's especially relevant when you're replacing an existing breaker and need to retain the 20A rating, single-pole setup, Type P bolt-on mounting, 120VAC rating, and original physical footprint.

A quick compatibility check is worthwhile before installation. Don't go by amperage alone. Check the existing breaker part number, mounting arrangement, pole count, voltage, interrupting rating, and dimensions. For equipment designed around the P120 specifications shown above, this replacement fits that existing application.

As with any circuit breaker replacement, qualified electrical personnel should handle installation and complete it in accordance with the equipment requirements and applicable electrical codes.
