MCCB NS Schneider
Abbreviation MCCB is Molded Case Circuit Breaker. MCCB function is as an intermediate voltage circuit breaker.
In choosing a circuit breaker things to consider are:
- Characteristics of the system in which the circuit breaker is installed. - The need for continuity of service of electrical resources. - Applicable rules and standards of protection.
System characteristics 1. System voltage The operating voltage of the circuit breaker must be greater or minimum equal to the system voltage. 2. Frequency of system The rated frequency of the circuit breaker should match the frequency of the system. Merlin Gerin Circuit Breaker can operate at frequencies 50 or 60 Hz. 3. The rated current The rated current of the circuit breaker shall be adjusted to the magnitude of the load current passed by the cable, and shall be less than the permitted threshold current passing through the cable. 4. Termination Capacity The breaking capacity of the circuit breaker shall be at least equal to the prospective short-circuit current that may occur at an installation point where the circuit breaker is installed. 5. Number of pole from circuit breaker 6. The number of poles from the circuit breaker is highly dependent on the earthing system of the system. We also provide MCB / Circuit Breaker.
