Used and surplus industrial circuit breakers for sale. MRO Exchange carries a rotating selection of industrial circuit breakers available for immediate purchase and fast nationwide shipping.

Industrial circuit breakers protect electrical circuits and connected equipment from overcurrent conditions in machine tool panels, motor control centers, switchgear assemblies, and power distribution systems. Finding a direct replacement for a specific frame size, trip rating, and interrupting capacity outside of standard distribution channels is a common challenge, particularly for older panels where the original breaker model has been superseded or discontinued.

Selecting the right circuit breaker:
Frame size determines the physical mounting and termination configuration and must match the existing installation. Trip rating must be sized correctly for the circuit being protected. Interrupting capacity must meet or exceed the available fault current at the point of installation. Voltage rating must be appropriate for the circuit voltage. MRO Exchange lists manufacturer, model number, and condition for every circuit breaker in our inventory to support your selection before purchasing.

Our circuit breaker inventory rotates regularly. If you do not see your specific model listed, contact us directly. Every circuit breaker listed on MRO Exchange ships nationwide from our facility in Illinois at prices well below new distributor cost.
