- Product Description
These QOT series miniature circuit breakers plug into place in NQOD panelboards and QO load centers without requiring DIN rail or bolts, so they're easier to install than bolt-on and unit-mount breakers. These breakers are tandem, so they have two smaller breakers built into one regular-sized breaker body, providing two separate circuits in the space of one slot. They interrupt currents when low-level faults are detected in the circuit. They connect to the power supply through bus bars, which eliminates the need to pigtail wires and helps organize the panelboard or load center.
