Breaker Repair

REPAIR

Our team of repair experts visually inspects each breaker for worn or missing mechanisms. They perform electrical testing and analysis to determine any issues with the breaker. Upon approval for repair, defective parts are removed and replaced with new parts. A final test and inspection are performed before the breaker is returned.

REFURBISH

During the breaker refurbishment process, our expert technicians completely disassemble, inspect, clean, and plate and paint if required. We then reassemble the breaker with replacement parts before a final test and inspection prior to shipment.

RETROFIT

Our Industrial circuit breaker retrofitting services can provide a more robust and reliable system to reduce losses that can happen during down time and upgrades. Retrofit components can be installed using existing facilities, require no additional space, and can save up to four times and space of replacement with new systems.
