Product FAQs
7 answersCan the QRH23B150 replace older QJ frame circuit breakers?
Yes, the Siemens QR series is engineered with the same form factor and mounting as the legacy QJ series. The QRH23B150 serves as a direct drop-in replacement for the obsolete QJH23B150.
Does the QRH23B150 come with line and load side lugs?
Load side lugs are supplied as standard on this bolt-on breaker. They accept copper or aluminum conductors from 3 AWG to 300 kcmil. Line side connections are typically bolted directly to the panel bus.
Can the Siemens QRH23B150 be reverse fed?
Yes, this circuit breaker supports reverse feed setups for installation in compatible Siemens P1, P2, and P3 panelboards or switchboards.
What does the H in QRH23B150 indicate?
In the Siemens QR family, the H designates a high interrupting capacity. The QRH23B150 delivers a 25kAIC rating at 240VAC, providing greater fault protection than standard 10kAIC QR2 models.
Is the QRH23B150 HACR rated for HVAC applications?
Yes, this molded case circuit breaker is HACR rated, meaning it is approved to protect heating, air conditioning, and refrigeration equipment circuits.
What ambient temperature is this breaker calibrated for?
The QRH23B150 is calibrated for standard operation at a 40 degrees Celsius ambient temperature. Operating the breaker in higher temperature environments will require derating.
Are the trip settings on the QRH23B150 adjustable?
No, this breaker features a non-interchangeable thermal magnetic trip unit with fixed long time and instantaneous functions. The trip parameters cannot be adjusted in the field.
