ER12-200J3PB

ER12-200J3PB disconnected switch is a solenoid control switch developed by Electric Co., Ltd. It is widely used in various control circuit circuits, isolation protection of group switch and overload protection. ER12-200J3PB disconnected switch can also be used in the process of controlling the flow of electricity.

ER12-200J3PB disconnected switch consists of coil, contact bridge, contact arm, base and other components. The coil is powered off by external control circuit, when the coil current stops working, the wheel gear and the armature move relatively, the contact bridge loses contact with the contact arm, at this time, the normally closed contact and the normally open contact disconnect.

ER12-200J3PB disconnected switch can be used in various industrial control devices, such as circuit breakers, electric actuators and so on. It is mainly used to connect and open the power supply of the load, so as to ensure the normal operation of the whole equipment.

In addition to the above application field, ER12-200J3PB disconnected switch is also used in the main circuit of heavy electronics equipment, as well as in the motor overload protection and related light control applications. In the process of overload protection of motor, ER12-200J3PB disconnected switch can protect motor from loss and collision caused by overload current, so that the life of motor and the whole equipment is prolonged effectively.

In addition, the ER12-200J3PB disconnected switch can also be used as starting or switching devices in any application field. When the external control signal is generated, the contact bridge of the ER12-200J3PB disconnected switch will start to conduct electricity, and then the relay will open in time to complete the start or switching of the equipment.

Work Principle: Working principle of ER12-200J3PB disconnected switch is simple. When the coil is powered off, the contact arm will lose contact with the contact bridge, and only the normally open contact is disconnected, and the normally closed contact will remain closed.

Conclusion:

ER12-200J3PB disconnected switch is widely used in various industrial control devices due to its excellent performance and reliable functions. This device is mainly used to isolate the control circuit and the load circuit, protect the load circuit and its devices from overload and collision, as well as provide high protection for the whole equipment. Therefore, ER12-200J3PB disconnected switch has been widely used in the various application fields.
