Product FAQs
4 answersWhich specific Eaton panelboards are compatible with the QBHW2030S?
This breaker is designed for Eaton Cutler-Hammer Pow-R-Line series panelboards, specifically fitting the PRL1a, PRL2a, PRL1X, and PRL2X models.
What does the S suffix mean in the QBHW2030S catalog number?
The S suffix indicates that this breaker is equipped with a factory-installed shunt trip. This allows the breaker to be tripped remotely when an external voltage signal is applied to the shunt trip terminals.
What is the difference between the QBHW2030S and a standard BAB breaker?
While both share the same physical BAB frame size and bolt-on mounting, the QBHW series features a higher interrupting rating of 22 kAIC at 120/240 VAC, compared to the 10 kAIC rating of standard BAB breakers.
How much panel space does the QBHW2030S require?
As a 2-pole Quicklag breaker, it requires two 1-inch spaces in the panelboard, taking up a total width of 2 inches.
