This bolt-on Quicklag breaker is designed specifically for Eaton Pow-R-Line panelboards. It is not compatible with standard load centers that require plug-on breakers.
The S suffix indicates the breaker is equipped with a factory-installed 120VAC shunt trip. This accessory draws approximately 2.6A at 120VAC and allows the breaker to be opened remotely for emergency or automated shutdowns.
This two-pole breaker requires three circuit spaces in the panelboard. The breaker itself occupies two spaces, and the factory-installed shunt trip module requires one additional space.
The factory-installed shunt trip includes two black wire leads that exit the breaker housing. These non-polarity sensitive leads must be connected to an external 120VAC control circuit, such as a fire alarm panel or emergency stop button, to operate the remote trip function.
Yes, the QBHW series shares the same physical dimensions and bolt-on mounting as the BAB series. The QBHW2060S provides a higher interrupting capacity of 22kAIC, making it a suitable upgrade for a 10kAIC BAB2060S.
Yes, Eaton acquired the Cutler-Hammer and Westinghouse lines. The QBHW2060S is a direct replacement for older Cutler-Hammer or Westinghouse QBHW breakers with the same specifications and shunt trip requirement.
No, this is a standard thermal-magnetic circuit breaker providing overload and short-circuit protection. It does not include GFCI or AFCI circuitry.
