QOU120 - 20 Amp Circuit Breaker

QOU120 - 20 Amp Circuit Breaker

The QOU120 is a 20 Amp, single-pole Type QOU circuit breaker used to protect 120VAC electrical circuits from overloads and short circuits. It features a thermal magnetic trip unit, allowing it to respond to both sustained overload conditions and higher fault currents before damage can occur to the circuit. This breaker uses a cable-in/cable-out connection, making it suitable for compatible electrical distribution equipment that requires direct cable terminations. Its compact design also helps when working in panels where space is limited. The 10kA interrupting rating at 120VAC allows the breaker to safely interrupt fault currents within its rated capacity. Whether you're replacing an existing breaker or maintaining electrical equipment, the QOU120 is a dependable option for compatible systems.
