Product FAQs
7 answersCan I use the QRH23B200 to replace an older Siemens QJ frame breaker?
Yes. The Siemens QR frame is the direct successor to the legacy QJ frame circuit breakers. It shares the exact same physical form factor and mounting footprint, allowing for a straightforward drop-in retrofit in existing panels and switchboards.
What size and type of wire do the standard lugs on the QRH23B200 accept?
The factory-installed line and load lugs (catalog number 3TA1QR300) are designed to accept 3 AWG to 300 kcmil wire. They are dual-rated for both copper (Cu) and aluminum (Al) conductors.
What does the QRH designation indicate compared to standard QR models?
The QRH designation indicates a higher short circuit interrupting capacity. While standard QR2 series breakers provide a 10kAIC rating at 240VAC, the QRH2 series is upgraded to safely interrupt fault currents up to 25kAIC.
Is this circuit breaker rated for use with heating, air conditioning, and refrigeration systems?
Yes, the QRH23B200 is HACR rated, making it fully suitable and compliant for protecting multi-motor HVAC and commercial refrigeration equipment.
Can the QRH23B200 be reverse fed in a panelboard?
Yes, this thermal magnetic QR-frame circuit breaker is UL Listed for reverse feed applications, allowing flexibility when wiring main or branch configurations.
Are internal accessories field-installable on this breaker?
Yes, the Siemens QR frame design features dedicated internal pockets. This allows panel builders to field-install accessories like shunt trips and auxiliary switches without increasing the physical mounting footprint of the breaker.
How can I manually test the mechanical operation of the breaker?
The QRH23B200 includes a built-in push-to-trip button on the faceplate. This allows licensed electricians to manually trip the mechanism to verify that the internal linkages are operating properly.
