The Role Of The Main Shield Of The Low Voltage Pole Mounted Circuit Breaker In The Arcing Process

The Lv Pole Mounted Circuit Breakers main shield prevents arc products from splashing onto the inner wall of the insulating housing during arcing, thereby reducing the insulation strength of the housing. Without the protection of the main shield, these splashes could cause carbonization of the insulation material, thereby reducing the insulation strength of the circuit breaker housing and affecting the safe and stable operation of the equipment.
