Overview
The Siemens B120 is a 20-amp Single-Pole Circuit Breaker designed for use with Siemens BL and BW series load centers, providing reliable overcurrent protection across a single-pole configuration.
Single-pole breakers are ideal for 120V branch circuits such as lighting, outlets, and small appliances. The thermal-magnetic trip mechanism protects against both overload and short-circuit conditions,
disconnecting the circuit automatically when a fault is detected.
