The P120 SIEMENS Bulldog Pushmatic 1P20A 120V Branch Push-In 10kA Breaker is designed for reliable performance in residential and commercial applications. With a 20 amp capacity and 10kA interrupting rating, this circuit breaker ensures your electrical systems are protected. Easy to install and built for durability, it’s the perfect choice for your needs.
Unlike conventional toggle-style breakers, the Bulldog Pushmatic uses a push-button mechanism — the button pops out when a fault trips the breaker, and you push it back in to reset. This design is unique to Pushmatic panels and means P-Series breakers are not interchangeable with any modern breaker line.
The Bulldog Pushmatic line was discontinued decades ago, making the P120 an obsolete and hard-to-find part. Northern Breaker Group specialises in sourcing exactly these kinds of legacy breakers — contact us for current availability and to request a quote.
A full panel replacement is one option, but it involves a licensed electrician and a permit, which can be costly. Many customers choose to source a replacement P120 to keep their existing Pushmatic panel operational. We can help you find the breaker — reach out to our team for availability.
