Browse Store You're probably aware that EMSCO is a top provider of used, reconditioned, and surplus industrial electrical equipment. However, you might not know that beyond just being the largest supplier, we also can tailor our products to your exact needs. Let's discuss one aspect of this customization: trip units, specifically the AC Pro and AC Pro II trip units.
We integrate the AC Pro / Pro II trip unit into various brands of molded case circuit breakers, covering major names like GE, Square D, Eaton, Cutler-Hammer/Westinghouse, Siemens, and more. These trip units can be customized to match your requirements regarding amperage, voltage, and function (such as LSIG). An added perk of using AC Pro and AC Pro II trip units is that they enable us to add ground fault protection to many breakers that were originally not manufactured with this capability.
For you, the customer, this means added assurance that your breaker has undergone comprehensive testing with a new trip unit installed. Our efficient turnaround time ensures that installation and testing can be completed in just a few days.
The AC Pro and AC Pro II trip units are compatible with the following brands and styles:
- GE, including Wave Pro, Power Break, and Power Break II breakers
- Square D, including Master Pact, NX, SED/SEF breakers
- Eaton Cutler-Hammer/ Westinghouse, including Magnum DS, PC, SPCB SCB, SPB breakers
- Siemens, including SB, WL breakers
If you need a molded case circuit breaker or are considering adding a trip unit, feel free to reach out to our sales team at 1-800-328-1842! We're available Monday through Friday from 8 AM to 5 PM Central Time.
