Product FAQs
6 answersWhat panelboards are compatible with the Eaton QBHW3030HS?
This Quicklag miniature circuit breaker is designed specifically for use in Eaton Pow-R-Line panelboards.
What does the "HS" suffix indicate on the QBHW3030HS?
The "HS" suffix designates that this breaker includes a factory-installed 120-240V shunt trip, which allows the breaker to be tripped remotely via an external control signal.
How does the QBHW3030HS connect to the panelboard bus?
It is a bolt-on circuit breaker, meaning it fastens directly to the panel bus with screws to provide a secure, vibration-resistant electrical connection.
What type of protection does the QBHW3030HS provide?
It features a thermal-magnetic trip unit with fixed long-time and instantaneous (LI) trip functions to protect circuits against overloads and short circuits.
Can I substitute a standard QBHW3030 for the QBHW3030HS?
Only if your application does not require remote tripping. The QBHW3030HS includes a built-in shunt trip, whereas the standard QBHW3030 does not have this remote trip capability.
Why is the frame type listed as BAB for this QBHW breaker?
In Eaton's Quicklag family, BAB and QBHW breakers share the same physical frame dimensions and bolt-on mounting style. The primary difference is that QBHW breakers offer a higher 22kAIC interrupting rating compared to the standard 10kAIC of BAB breakers.
