Featuring series PowerPact, EcoStruxure, and MasterPact, Siemens smart circuit breakers can perform 3 key functions: protection, switching, and monitoring.

Siemens tandem breaker is the breaker type with two rockers, which is also known as a double pole circuit breaker. Compared with a single pole breaker, tandem breakers can control two branches at the same time. For lighting circuits, tandem breakers can cut off live lines and zero lines at the same time, which is safer in use. As a market-proven model, the Siemens QP tandem breaker offers superior circuit protection performance at the lowest price.

Siemens shunt trip breaker is an optional accessory in a circuit breaker that mechanically trips the breaker when power is applied to the shunt trip terminals.
