Product FAQs

6 answers
What 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.
