MCCB air switch and the difference

Air switch is the air circuit breaker in the circuit as connected, breaking and carrying rated current and short-circuit, overload fault current, and can line and load overload, short circuit, Air circuit breaker and other circumstances, quickly breaking the circuit, for reliable protection. Breaker dynamic and static contact and touch bar design pattern varied, but to improve the circuit electri cenergy meter capacity is the main purpose. Currently, the use of certain contact structure, breaking the short-circuit electric meter peak limiting principle, to improve the breaking capacity of the circuit breaker has a significant role, and are widely used.
Molded case circuit breaker automatically interrupts the current flowing in the current exceeds the trip. Molded refers to a device with a plastic insulator shell, used to isolate conductors and earthed metal parts. MCCB usually contain thermal magnetic trip units, and large models will be equipped with solid state trip MCCB sensor.
