Description
Designed for systems with higher available fault currents, the Siemens BF220AH offers a robust 22kAIC rating at 120/240VAC. This 2-pole, 20-amp bolt-on breaker provides 5mA Class A ground fault protection with built-in self-testing functionality. It fastens securely into Siemens P1, P2, and P3 panelboards for commercial and industrial applications. While currently being replaced by the B220GFH, it remains an excellent choice for exact component matching.Specifications
