Eaton / Cutler-Hammer QBHW2015S Miniature Circuit Breaker

This Quicklag miniature circuit breaker is specifically designed for installation in Eaton Pow-R-Line panelboards.

The S suffix denotes that this breaker is equipped with a factory-installed 120/208/240V AC shunt trip. This allows the breaker to be tripped remotely by applying voltage to the shunt trip coil, which is commonly used for emergency shutdown or control systems.

Yes, while primarily used for AC circuits with a 22kAIC rating at 120/240V AC, this breaker is also rated to safely interrupt up to 5kA at 48V DC.

This breaker is equipped with standard box lug terminals that accept wire sizes from 14 AWG to 4 AWG, providing a secure connection for a wide range of conductor sizes.

The fixed thermal-magnetic trip unit provides dual protection. The thermal component features a long-time delay to prevent nuisance tripping from temporary overloads, while the magnetic component provides an instantaneous trip response to clear severe short circuits quickly.

It utilizes a bolt-on connection that fastens directly to the panelboard bus. This provides a highly secure, vibration-resistant mechanical and electrical connection compared to standard plug-on designs.

Yes, this breaker is both HACR rated for use with heating, air conditioning, and refrigeration equipment, and SWD rated for switching duty applications such as fluorescent lighting circuits.
