Tripping, cleaning and lubricating a circuit breaker are part of normal maintenance procedures. Unlike contactor circuits which are capable of well over 100,000 operations without falling apart, circuit breakers close and trip more forcefully and will ultimately pound themselves to pieces if used as motor starters.
 The first step in a circuit breaker rebuild is to manually test the operating mechanism to be sure no parts are broken. DYMAX then performs preliminary Megger and ductor tests. The circuit breaker is disassembled to its smallest component. All current-carrying parts are silver plated and the breaker frame is bead-blasted, primed and painted.
Once DYMAX has inspected and reworked every component of the circuit breaker, we assemble the breaker and install a new solid state overcurrent protection device.  We lubricate all moving parts with the manufacturer's approved lubricant, and all current-carrying parts with contact lubricant. DYMAX then adjusts the circuit breaker per manufacturer's specifications.
The remanufactured circuit breaker is fully inspected, Megger and ductor tested, high current tested, then packaged and delivered.
DYMAX offers:
- On-site or in-shop troubleshooting and repair
- On-site or in-shop breaker repair and testing
- In-shop circuit breaker retrofit to vacuum or gas operation
