Air Breaker

Air frame circuit breakers have a steel frame skeletal in nature. The design allows for easy access to the mechanical operator, accessories, and current carrying components. With this open type construction maintenance is simplified, however the openness of the design allows for environmental contamination which can lead to more frequent maintenance requirements.


Every air breaker that leaves our facility is fully refurbished or remanufactured. In addition to NETA/ANSI testing specifications, we measure current, voltage, and timing for all motors, closing coils, UVR’s and shunt trips. This provides you unparalleled data collection and documentation.


If you do not find the breaker for your requiments in our inventory please email or call as we can build out the breaker accessories to your specific application. There is also inventory that has not been entered.
