Product FAQs
6 answersWhat does the "HS" suffix in the QBHW3100HS catalog number mean?
The "HS" suffix indicates that this breaker is equipped with a factory-installed 120 to 240V AC shunt trip. This accessory allows the breaker to be tripped remotely when a voltage signal is applied.
What is the difference between the QBHW3100HS and the standard QBHW3100?
While both are 100A, 3-pole, 22kAIC bolt-on breakers, the QBHW3100HS includes a factory-installed shunt trip for remote tripping. The standard QBHW3100 does not include this accessory.
Which panelboards are compatible with the QBHW3100HS?
This Quicklag breaker is designed for bolt-on installation in Eaton Pow-R-Line panelboards. It is also backwards compatible with many legacy Cutler-Hammer and Westinghouse panelboards that accept BAB or QBHW frame breakers.
How does the QBHW3100HS mount to the panelboard?
It utilizes a bolt-on connection, meaning the breaker terminals bolt directly to the panelboard busbars. This provides a secure connection that is highly resistant to vibration and thermal cycling.
Can I adjust the trip settings on the QBHW3100HS?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip thresholds are factory-set and cannot be modified in the field.
Can the QBHW3100HS be used to upgrade a BAB3100HS?
Yes, the QBHW3100HS shares the same physical dimensions and bolt-on mounting as the BAB3100HS, but it provides a higher interrupting rating of 22kAIC compared to the 10kAIC rating of the BAB series.
