Product FAQs
6 answersWhich panels are compatible with the B115DF circuit breaker?
The B115DF is a BL-series bolt-on breaker designed specifically for Siemens P1, P2, P3, P4, and P5 commercial panelboards. It cannot be installed in standard Siemens residential plug-on load centers.
What is the plug-on equivalent to the B115DF for residential load centers?
If you need a 15A dual function breaker for a standard Siemens plug-on load center, use the Q-series Q115DF instead of this bolt-on BL-series model.
How is the neutral connected on the B115DF?
This breaker features a pigtail neutral connection. The coiled white pigtail wire must be routed and connected directly to the panelboard neutral bar to ensure proper AFCI and GFCI operation.
How do I identify the cause of a trip on the B115DF?
This breaker features an LED trip indicator. After a trip event, the LED helps pinpoint whether the circuit was interrupted due to an arc fault, a ground fault, or a standard overcurrent condition, simplifying troubleshooting.
What does a dual function circuit breaker protect against?
A dual function breaker combines Arc Fault Circuit Interrupter (AFCI) and Ground Fault Circuit Interrupter (GFCI) technology. It protects against electrical fires caused by arcing faults and prevents electrical shock from ground faults in a single device.
Does this breaker include a self-test feature?
Yes, Siemens dual function breakers include an automated self-test feature that routinely verifies the AFCI and GFCI protection circuits are functioning correctly to meet NEC requirements.
