Siemens P120 Circuit Breaker

Siemens P120 is a 20‑amp, single‑pole Pushmatic circuit breaker designed for 120/240‑volt AC service in ITE/Siemens Pushmatic panel boards. This molded‑case breaker provides branch‑circuit protection for a single 120/240‑V circuit and carries a 10 kA interrupt rating at 120 V. As part of the ITE Pushmatic line, the P120 is intended for use in compatible Pushmatic panels and is commonly installed to protect residential lighting, receptacle, and small‑appliance circuits. The 1‑pole configuration and 20‑amp rating align with standard branch loads, with thermal‑magnetic trip characteristics that respond to overloads and short circuits. The P120 serves as a direct replacement option for ITE/P‑series installations and is compatible with Siemens/ITE Pushmatic equipment, enabling consistent protection across legacy electrical systems.
