Product FAQs
8 answersWhat is the lug torque specification for the HQR22B250L?
For 3 AWG to 1/0 AWG wire, torque the lugs to 100 in-lbs. For 2/0 AWG to 300 kcmil wire, torque the lugs to 225 in-lbs.
What does the L suffix in the HQR22B250L catalog number indicate?
The L suffix indicates that the breaker is supplied with both line and load side lugs factory installed. Standard models without this suffix are only supplied with load side lugs.
What is the difference between the Siemens QR22B250L and the HQR22B250L?
The primary difference is the interrupting rating. The QR22B250L is rated for 10kA at 240VAC, while the HQR22B250L is a high-interrupting version rated for 65kA at 240VAC.
Can the HQR22B250L be reverse fed?
Yes, this breaker features a cable-in, cable-out design and is suitable for reverse feed applications.
Does this 2-pole breaker accept internal accessories?
Yes, the 2-pole HQR2 frame includes one accessory pocket for field-installable internal accessories like a shunt trip or auxiliary switch.
What is the standard calibration temperature for the HQR22B250L?
This breaker is calibrated for use in a 40 degrees Celsius ambient temperature. Operating the breaker in higher ambient temperatures will require derating.
Does the HQR22B250L include a push-to-trip feature?
Yes, it includes a push-to-trip button on the face of the breaker to manually test the mechanical tripping mechanism.
Can the HQR22B250L be used to replace older QJ frame breakers?
Yes, the QR frame series shares the same form factor and mounting footprint as legacy QJ breakers, making it suitable for direct retrofits in existing Siemens panelboards and switchboards.
