Tips for using miniature circuit breaker

Miniature circuit breaker is mainly used for circuit overload, short circuit, over current, loss of voltage, under voltage, grounding, leakage, dual power automatic switching and protection and operation of the motor during infrequent starting. The selection principle is in addition to complying with low-voltage electrical appliances.

• The rated voltage of the miniature circuit breaker should not be less than the rated voltage of the circuit.
• The rated current of the miniature circuit breaker and the rated current of the overcurrent release are not less than the calculated current of the circuit.
• The rated short-circuit breaking capacity of the miniature circuit breaker is not less than the maximum short-circuit current in the circuit.
• When selecting a type of distribution circuit breaker, it is necessary to consider the coordination between short-delay short-circuit making and breaking capacity and time-delay protection levels.
• The rated voltage of the miniature circuit breaker undervoltage release is equal to the rated voltage of the circuit.
• When it is used for motor protection, the starting current of the motor should be considered when selecting the circuit breaker and it will not operate during the starting time.
• The selection of miniature circuit breaker should also consider the selective coordination of circuit breaker and circuit breaker, circuit breaker and fuse.
