Siemens Q115 Circuit Breaker (120v, 15A, 1P)

These Q series miniature circuit breakers plug into place in panelboards and EQ load centers and don't require bolting, so they're easier to install than bolt-on breakers. 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.
