Siemens B215AF AFCI Miniature Circuit Breaker

This bolt-on breaker is engineered specifically for Siemens commercial panelboards, including the P1, P2, P3, P4, and P5 series. It is not compatible with standard residential load centers.

No, the B215AF features a bolt-on mounting style and is not interchangeable with plug-on circuit breakers. It requires a compatible bolt-on panelboard chassis.

The factory-installed load lugs are dual-rated for both copper and aluminum conductors. They accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire, which accommodates standard 15A branch circuit wiring.

The B215AF utilizes a pigtail neutral connection. The coiled white pigtail wire must be routed and secured directly to the neutral bus bar in the panelboard to ensure proper arc fault detection.

Yes, as a 2-pole AFCI breaker, the B215AF is designed to handle shared neutral applications in 120/240V multi-wire branch circuits. The panel neutral must be properly connected via the breaker's pigtail to prevent nuisance tripping.

Yes. If your electrical system requires a higher fault current rating, the Siemens B215AFH is the high-interrupting equivalent, offering a 22kAIC rating at 120/240VAC instead of the standard 10kAIC.

This breaker combines standard thermal-magnetic protection for overloads and short circuits with Arc Fault Circuit Interrupter (AFCI) technology. The AFCI component actively monitors the circuit to detect and mitigate dangerous arcing faults that can cause electrical fires.

No, the B215AF features fixed thermal and fixed magnetic trip mechanisms. It provides standard Long-Time and Instantaneous (LI) trip functions without adjustable dials.
