Thermal magnetic MCCB

ARM5 series thermal magnetic type double-breaker mccb 200ka icu=ics Thermal ajustable type mccb 400VAC/415VAC/550VAC/ 690VAC/800VAC400A 630A 3/4 Poles

Rated Current : 400A、500A、630A

Number Of Poles : 3P / 4P

Rated Working Voltage : 400V/690V

    MCCB Highlights

    The reasonable structure design of moving and fixed contacts makes the short circuit peak value and energy of this series of products I²t much smaller than expected

    fasdfp8ahgfh6ab

    Working principle: the current flows in from the fixed contact
    1, flows out from the fixed contact
    2, through the moving, fixed silver contact and the moving contact. The moving contact quickly disconnects under the action of strong electric repulsion force (Holm force and Lorentz force) to improve the breaking speed.

    Air blowing design: when the short circuit large current occur in the circuit, the gas producing parts will generate other gas under the high temperature of the arc, the air pressure in the contact unit box increases rapidly, and a high-speed air flow can be formed through the air outlet of the arc extinguishing chamber, which can effectively extinguish the arc.
