Siemens Q125 Circuit Breaker 1 Pole 25 Amp AC

Siemens Q125 is a 1-pole, 25-amp circuit breaker in the QP family designed for plug-on installation in compatible Siemens panels to protect a single branch circuit in 120/240 VAC systems. It provides thermal-magnetic overcurrent protection with a 10 kA interrupting capacity, allowing it to safely break faults up to 10,000 amps at its rated voltage. As a QP-type device, the Q125 fits residential and light-commercial distributions that use Siemens QP breakers, and is commonly used to safeguard circuits such as lighting and receptacles in standard panelboards; the unit is specified as 25 A, 1P, 120/240 V, and is readily available from major retailers and distributors.
