IEC specifications circuit breaker maintenance

Molded Case Circuit breakers are used in Residential, Commercial and Industrial distribution systems. These important protective devices are extremely reliable if properly maintained. The exact lifetime of a MCCB is determined by the circuit breaker's operation duty and its environment. NEMA publication AB 4-2009 is a free guideline that discusses the inspection and preventive maintenance of ...

  • Standard IEC 60947-2 | CsanyiGroup

    Standard IEC 60947-2 applies to circuit-breakers and their associated trip units. Circuit-breaker operating data depend on the trip units or relays that control their opening in specific conditions. This standard defines the main data of industrial circuit-breakers: their classification: utilisation category, suitability for isolation, etc.
