Product FAQs
5 answersCan the Siemens Q125 replace an older Murray MP125 breaker?
Yes. Siemens phased out the Murray brand and designated the QP series as the official, UL-listed replacement for Murray MP-T breakers. The Q125 directly replaces the obsolete Murray MP125.
Is the Siemens Q125 HACR rated for use with HVAC equipment?
Yes, this breaker is HACR rated. It is suitable for protecting heating, air conditioning, and refrigeration circuits that require a HACR-designated overcurrent device.
What types of electrical panels accept the Q125 breaker?
The Q125 is designed for plug-on installation in Siemens Load Centers and Siemens P1 Panelboards. It is also backward compatible with older ITE EQ-P load centers and Murray panels that accept QP or MP-T type breakers.
Does the Q125 provide GFCI or AFCI protection?
No. The Q125 is a standard thermal-magnetic circuit breaker. It provides essential overload and short-circuit protection but does not include Ground Fault Circuit Interrupter (GFCI) or Arc Fault Circuit Interrupter (AFCI) functionality.
Does the Q125 breaker feature Insta-Wire connectors?
Yes, Siemens QP breakers include the Insta-Wire feature. The terminal screws are backed out and ready for wire insertion straight from the factory, which speeds up the installation process.
