Product FAQs
7 answersWhat panelboards are compatible with the HQR22B150HL circuit breaker?
This breaker is designed for use in Siemens enclosures as well as P1, P2, and P3 panelboards. It can be installed as a main or subfeed breaker depending on the specific panel configuration.
Can the HQR22B150HL replace older Siemens QJ frame breakers?
Yes. The SENTRON QR frame is the direct successor to the legacy QJ frame. It shares the exact same physical footprint and mounting configuration, making it a direct drop-in replacement for older 150A QJ breakers.
What does the L suffix mean in the HQR22B150HL catalog number?
The L suffix indicates that the breaker is supplied with factory-installed line and load side lugs. These standard lugs accept 3 AWG to 300 kcmil aluminum or copper wire.
Does the HQR22B150HL support field-installable accessories?
Yes. Unlike the older QJ frames that required factory installation, the QR family allows for field-installable internal accessories. You can easily add shunt trips or auxiliary switches by removing the faceplate and plugging the accessory into the designated pocket.
What does the H in the HQR22B150HL part number signify?
The H designates this as a high-interrupting QR frame breaker. It provides a 100kAIC rating at 240V AC, which is significantly higher than standard QR frames, making it suitable for commercial and industrial systems with high available fault currents.
Can I adjust the trip settings on the HQR22B150HL?
No. This breaker utilizes a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous (LI) functions. It does not offer adjustable trip settings.
How can I manually test the mechanical operation of this breaker?
The HQR22B150HL features a built-in push-to-trip button on the front of the device. Pressing this button manually trips the mechanism, allowing you to verify that the internal linkages are operating correctly without requiring an actual overcurrent event.
