Siemens AG NSB P215 Molded Case Circuit Breaker

Siemens NSB P215 Molded Case Circuit Breaker is a two-pole, 15-amp molded-case protection device designed for 120/240 V AC service and bolt-on panelboard mounting in legacy Siemens/ITE/Murray installations. It uses a thermal-magnetic trip unit that delivers long-time and instantaneous overcurrent protection, with an interrupting rating of 10,000 A at 240 V. As part of the P-series Pushmatic family, the NSB P215 is intended for residential and light commercial load centers where two-pole protection is required on 240 V circuits; its compact MCCB construction helps protect branch circuits and equipment from overloads while providing predictable tripping characteristics. This model is commonly deployed in older panels that accept P-type breakers and is suitable for applications such as lighting, receptacle circuits, and small-appliance circuits within 120/240 V systems.
