    Circuit Breaker Dimension

    circuit breaker dimensionTips: Main parameters of the circuit breaker

    1. Rated voltage: The rated voltage of the main contact of the circuit breaker, it is the voltage value guaranteeing the long-term normal operation of the contact terminal of the contactor.
    2. Rated current: Rated current of the main contact terminal of the circuit breaker, it is the current value guaranteeing the long-term normal operation of the contact terminal of the contactor.
    3. Tripping current: It is the set value of the action of the current release. When the circuit is short-circuit or the overload condition is serious, the load current is higher than the tripping current, the main contact terminal of the circuit breaker disconnects.
    4. Overload protection current, time curve: it is the inverse-time characteristic curve. A higher overload current leads to a shorter action time of the thermal release.
    5. Breaking capacity: Two indexes of rated limit short-circuit breaking capacity Icu and rated operation short-circuit breaking capacity Ics.
      The rated limit short-circuit breaking capacity Icu is the limit parameter of the breaking capacity of the circuit breaker. After breaking several short-circuit faults, the breaking capacity of the circuit breaker declines.
      The rated operation short-circuit breaking capacity Ics is a kind of breaking index of the circuit breaker. After breaking several short-circuit faults, it can still be guaranteed to have normal operation.
