QO2125 - 125 Amp Circuit Breaker

QO2125 - 125 Amp Circuit Breaker

The QO2125 is a 2-pole, 125-amp plug-on circuit breaker designed for use in compatible Type QO load centers and panelboards. It provides overcurrent and short-circuit protection for 120/240VAC electrical systems and has a 10kA interrupting rating.

Whether you're replacing a failed breaker or adding capacity to an existing panel, the QO2125 installs with a standard plug-on connection. It is suitable for applications that require a 125-amp, two-pole breaker. Its compact size makes it easy to work with inside the panel, while the thermal-magnetic trip mechanism responds to both overloads and short circuits to help protect wiring and connected equipment.

For anyone matching an existing Type QO breaker, the QO2125 offers the ratings and configuration needed for a straightforward replacement in compatible equipment.
