BF240 - 40Amp Circuit Breaker

BF240 - 40Amp Circuit Breaker

The Siemens BF240 is a 40 amp, 2-pole GFCI circuit breaker rated for your 120/240VAC applications. It provides thermal-magnetic overcurrent protection and 5 mA ground fault protection in a single device. Designed for use in compatible Siemens panelboards, the BF240 is commonly installed where both branch circuit protection and GFCI protection are required.

The breaker features a 10kAIC interrupting rating, bolt-on mounting, and molded case construction. Built to Siemens standards, it is intended for long-term service in properly maintained electrical systems.
