Product Description

These QOB series miniature circuit breakers are bolted into place in NQOD and NQ panelboards or interiors, so they're more stable than plug-in or unit-mount circuit breakers. They interrupt currents when low-level faults are detected in the circuit. They have a lug orientation to allow for straight-in wiring through bus bars, which eliminates the need to pigtail wires and helps organize the load center.
