Product FAQs
8 answersWhat load centers are compatible with the Q115DF circuit breaker?
The Q115DF is designed for use in Siemens EQ, EQL, SEQ, EQG, PL, and ES series load centers.
What is the ground fault trip sensitivity for this dual function breaker?
The GFCI portion of the Q115DF provides Class A protection with a 5mA trip sensitivity threshold.
What is the recommended torque specification for the box lugs on the Q115DF?
The terminal lugs should be torqued to 25 lb-in for both copper and aluminum conductors.
How does the Q115DF connect to the neutral bar?
This breaker features a pigtail neutral wire that must be routed and connected directly to the load center neutral bus bar. If your panel requires a plug-on neutral connection, you will need catalog number Q115DFN instead.
How do I interpret the LED trip indicators on this breaker?
If the top LED is illuminated, the breaker tripped due to a series arc fault. If both LEDs are lit, it indicates a ground fault or line-to-ground arcing. If no LEDs are lit after a trip, it was caused by a standard short circuit or thermal overload.
Does the Q115DF have a self-test feature?
Yes, this dual function breaker automatically and continuously tests its internal AFCI and GFCI circuitry. If the self-test detects a failure, the breaker will trip and lock out to ensure safety.
What is the difference between the Q115DF and Q115DFP?
The Q115DF and Q115DFP are the exact same breaker. The P suffix simply indicates retail clamshell packaging, while the Q115DF is typically sold in standard distributor packaging.
What is the correct padlocking device for the Q115DF?
To lock this single-pole breaker in the OFF position, use the Siemens ECPLD1 padlocking device.
