Built for commercial environments, the BF260AH is a thermal-magnetic GFCI circuit breaker from Siemens. It delivers 60A of current while providing critical personnel protection against electrical shock. This bolt-on unit is engineered to fit Siemens P1, P2, and P3 panelboards. It features a common trip mechanism for reliable performance. With an upgraded 22 kAIC rating, it handles higher fault currents. The breaker includes a self-test feature and is HACR rated.
Which panelboards are compatible with the Siemens BF260AH breaker?
The BF260AH is a bolt-on circuit breaker designed specifically for installation in Siemens P1, P2, and P3 panelboards.
What level of ground fault protection does the BF260AH provide?
This breaker provides Class A ground fault protection with a 5mA trip threshold, which is required for personnel safety against electrical shock.
What is the difference between the Siemens BF260A and the BF260AH?
The H in the BF260AH catalog number indicates a higher interrupting rating. The BF260AH is rated for 22kAIC at 240V, while the standard BF260A is rated for 10kAIC.
How is the neutral connection wired on this GFCI breaker?
The BF260AH is equipped with a pigtail neutral wire. This pigtail must be connected directly to the panelboard neutral bus to power the internal ground fault detection circuitry.
What wire sizes are accepted by the load lugs on the BF260AH?
The load-side terminal lugs accommodate 8 to 6 AWG copper conductors or 8 to 4 AWG aluminum conductors.
What type of trip mechanism does the BF260AH use?
It utilizes a thermal-magnetic trip unit with fixed long-time and instantaneous functions for standard overload and short-circuit protection, combined with integrated ground fault detection.
Can the BF260AH be used on circuits with a shared neutral?
Yes, this 2-pole GFCI breaker can be used on 120/240VAC multi-wire branch circuits. It monitors the current across both hot ungrounded conductors and the shared neutral to accurately detect ground faults.
