● Rated Current: 63-1600A

● Working Voltage: up to 690VAC~

● Poles Number: 3P, 4P

● Standard: IEC60947-3

The EDX series disconnector switch is designed for use in AC 50Hz electrical systems with a rated voltage of up to 660V and DC voltage up to 440V. It is primarily used in power distribution equipment in industrial enterprises, providing a means for infrequent switching, circuit breaking, and electrical isolation.

The EDX series disconnector switch complies with the IEC60947-3 and GB14048.3 standards, ensuring its adherence to international safety and performance requirements.

1. Altitude not more than 2000m.

2. The range of ambient temperature is from 5 degree to 40 degree .

3. Relative humidity not more than 95%.

4. The environment without any explosive medium.

5. The environment without any rain or snow attacking.

If the product is expected to be used in the environment where temperature is over +40 degree or below -5 degree to 40 degree , uses shall tell it to the manufacture.

● The switch adopts a modular design and is suitable for making and breaking circuits or electrical isolation. Above 1000A is only used for electrical isolation.

● The switch has 3 poles, 4 poles (3 poles + switchable neutral pole).

● There is a mark window under the switch to indicate the on-off state of the contact, and a rear observation window can be provided as required to directly observe the on-off state of the contact to ensure the reliability and safety of the switch operation.

● The handle can be directly installed on the switch for operation (referred to as in-cabinet operation), or it can be operated outside the power distribution cabinet door (referred to as out-of-cabinet operation) through the extension shaft, providing convenient operation.

● When the breaking position is "0", two to three locks can be used to lock the handle to prevent misoperation.
