Product FAQs
6 answersWhat panelboards are compatible with the QBHW3090HS?
This 3-pole Quicklag breaker is designed specifically for bolt-on installation in Eaton Pow-R-Line panelboards.
What wire size and material can be used with the terminals on this breaker?
The box lugs are rated for 8 AWG to 1/0 AWG wire and accept both copper (Cu) and aluminum (Al) conductors.
What does the HS suffix indicate on the QBHW3090HS?
The HS suffix signifies that this model includes a factory-installed 120V AC shunt trip device. This allows the breaker to be tripped remotely, which is often required for emergency shutdowns or safety-conscious environments.
How does the bolt-on connection benefit commercial installations?
The bolt-on mounting style ensures a highly secure connection to the panelboard busbar. This prevents the breaker from loosening over time, making it ideal for high-vibration industrial or commercial environments.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal-magnetic trip unit includes both long-time and instantaneous trip functions. The thermal component protects against sustained overloads, while the magnetic component responds immediately to short-circuit faults.
Are Eaton and Cutler-Hammer QBHW breakers the same?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture the Quicklag series under the Eaton brand. A QBHW3090HS labeled as Eaton is an exact, interchangeable match for one labeled Cutler-Hammer.
