BF120A - 20Amp Circuit Breaker Description
BF120A - 20Amp Circuit Breaker
The Siemens BF120A is a 20 amp, 1-pole GFCI breaker for 120V circuits. Part of the Siemens BLF2 series, it combines thermal-magnetic overcurrent protection with 5 mA ground fault protection in a single device. It interrupts overloads, short circuits, and ground faults, and works in your compatible Siemens panelboards.
It has a 10 kA interrupting rating and a bolt-on connection for installation in panelboards. The push-to-trip button allows technicians to check breaker operation during routine maintenance. Its compact size preserves panel layout and form.
