4H Neon Double-Pole Multi-gang integral switch
Description
The air switch is also a circuit breaker. It makes, breaks and carries the rated operating current in the circuit, and can provide reliable protection in the case of overload, short circuit and under-voltage of the line and motor. The moving and static contacts and contact rods of the circuit breaker are designed in a parallel shape. The electric repulsion generated by the short circuit is used to disconnect the moving and static contacts. It has high breaking capacity and strong current limiting characteristics. ． During a short circuit, the aromatic insulating material around the static contact vaporizes, cooling and extinguishing the arc, and the arcing distance is zero. The arc extinguishing chamber of the circuit breaker adopts a metal grid structure, and the contact system has a repulsive current limiting mechanism. Therefore, the circuit breaker has high breaking capacity and current limiting capacity. ． Equipped with double release. The inverse time-limited action is that the bimetallic sheet is heated and bent to cause the release to operate, and the instantaneous action is that the iron core street iron mechanism drives the release to operate. There are three tripping modes: thermal, electromagnetic and compound tripping. . The inside of the air switch is relatively sophisticated, but the principle is very simple. It has an inductor with 10 to 20 turns strung between the incoming and outgoing lines. When the current is sufficient, it pulls in and drives the mechanical lever to act for protection. It is safer and does not require changing insurance, so it is a good recommendation. The automatic air switch, also called a low-voltage circuit breaker, can be used to connect and break load circuits, and can also be used to control motors that start infrequently. Its function is equivalent to the sum of the functions of some or all electrical appliances such as knife switches, over-current relays, voltage-loss relays, thermal relays and leakage protectors. It is an important protective electrical appliance in low-voltage distribution networks.
