BF250A - 50Amp Circuit Breaker

BF250A - 50A 2-Pole 120/240V BLF GFCI Circuit Breaker

The Siemens BF250A is a 50 amp, 2-pole GFCI circuit breaker for your 120/240VAC electrical systems. It combines thermal-magnetic overcurrent protection and 5 mA Class A ground fault protection in a single breaker. The BF250A is intended for you to use in compatible Siemens panelboards where ground fault protection is required in addition to standard branch circuit protection.

This breaker carries a 10kAIC interrupting rating and is configured for panelboard mounting. It is commonly used in existing electrical distribution systems that require a 50A, 2-pole GFCI breaker with matching electrical and mechanical specifications. The molded case construction provides the form and fit you needed for maintenance, repair, and replacement applications. Built to Siemens standards, the BF250A is designed for long service life in properly maintained equipment.
