Siemens QJ22B125 Molded Case Circuit Breaker 2 Pole

Siemens QJ22B125 is a two-pole molded case circuit breaker from the Siemens QJ family, delivering 125 A at 240 V and described as a white-label device. As a molded case circuit breaker, it provides overcurrent protection for electrical circuits by interrupting current during overloads or short circuits, with a two-pole design protecting two conductors within a panel or enclosure. The model number QJ22B125 corresponds to a 2-pole configuration with a 125 A rating and 240 V maximum operating voltage, making it suitable for protecting feeders and branch circuits in electrical distribution systems where space is limited and reliable protection is required. The inclusion of 'white label' emphasizes its labeling on the unit, aiding quick identification during installation and maintenance.
