Product FAQs

6 answers
What does the HS1 suffix indicate on the BAB3020HS1 breaker?

The HS1 suffix signifies that the breaker includes a factory-installed 24/48V DC shunt trip, allowing the breaker to be tripped remotely via an external control signal.

How does the shunt trip function on the BAB3020HS1?

The integrated shunt trip allows for remote operation. When a 24V or 48V DC signal is applied to the shunt trip accessory leads, it mechanically trips the breaker to open the circuit.

Which panelboards are compatible with the BAB3020HS1?

This breaker is designed for commercial and industrial Eaton Pow-R-Line, Cutler-Hammer, and legacy Westinghouse panelboards that specifically accept bolt-on BAB frame circuit breakers.

Can the BAB3020HS1 replace older QNBL series breakers?

Yes, this BAB series breaker serves as a direct replacement for discontinued QNBL series breakers with matching pole, voltage, and amperage configurations.

How is the BAB3020HS1 installed in the panelboard?

This is a bolt-on circuit breaker, meaning it physically bolts directly to the panelboard busbar rather than snapping or plugging into place. Always ensure the panel is completely de-energized before installation.

Does the BAB3020HS1 include GFCI or AFCI protection?

No, this is a standard thermal-magnetic breaker providing overload and short-circuit protection. It does not feature ground fault or arc fault capabilities.

    Excellent Experience

    We placed our first order with superbreakers.com recently for a breaker we weren't able to acquire locally. I ordered the breaker way ahead of time because I've had issues with shipping for products purchased online in the past. The estimate for the item when I initially ordered was 3 days. Without adding an expedited shipping options, the breaker arrived the next day. We installed it this week, and so far so good. In my opinion, they sell quality parts and have excellent turn around time. Very impressed.
