Preventive Maintenance Guidance for Industrial Circuit Breakers

Inspection & Maintenance SchedulesFailing to Maintain BreakersRoutine Testing ProceduresRoutine Maintenance ProceduresAvoid Costly DowntimeRegular maintenance and testing of your circuit breakers are critical as planned production interruption will always be preferred over emergency industrial circuit breaker repair. The specific schedule and routine for your breakers will depend on the type of breaker (i.e., molded case, low-voltage, medium-voltage, and high-voltage) as well as the environment in which your systems are operating. For example, a clean production environment such as electronics manufacturing may require less frequent cleaning and maintenance than one that creates a substantial amount of dust and debris. Testing is another important aspect of routine maintenance for your industrial circuit breakers, and this routine is also determined by the type of breakers you are using. Molded case circuit breakers need very little maintenance. Low-voltage breakers should be inspected every one to three years, medium-voltage annually. High-voltage circuit breakers need the most frequent tests and inspections with a ma...Get price
