    Study Notes

    Circuit Breaker Specifications

    • Type C, K, or Z miniature circuit breakers required with nominal current options of 16 A or 20 A.
    • Designed for high-voltage bushings in power transformer installations facing thermal loads.
    • Must only be used with specified bushings—same type, manufacturer series, and undamaged.
    • Operation should comply with technical documentation and be carried out by qualified personnel.

    Inappropriate Use

    • Not suitable for extending the service life of bushings or performing safety-related functions.
    • Prohibited in environments with explosive gases, vapors, or dust.
