Normal Working and Installation Conditions

1、The ambient air temperature shall not exceed +40℃ and not be lower than-5℃.

2、The altitude of the installation site shall not exceed 2000m.

3、Humidity: When the maximum temperature is +40℃ , the relative humidity of the air does not exceed 50%. Higher relative humidity can be allowed at lower temperatures, such as reaching 90% at 20℃. Special measures should be taken for occasional condensation caused by temperature changes.

4、The pollution level of the surrounding environment is level 3.

5、The switch should be installed in a place without significant shaking, impact vibration, and invasion of rain and snow. At the same time, the installation location should be free of explosive hazardous media, and there should be no gas or dust in the media that can corrode metals and damage insulation.

Structure Characteristics

The product has a beautiful and innovative design. The switch is composed of a base, cover, and arc extinguishing chamber, all of which are made of arc resistant plastic and have a fully plastic structure. The static contact is directly installed on the base, and the arc extinguishing chamber is easy to disassemble. Each uses multiple arc extinguishing grids, enhancing the arc extinguishing ability and improving the contact life. The NT type fuse is installed inside the cover, which rotates in a fan-shaped manner and has a large electrical isolation distance to meet the requirements of the isolation switch. The cover can be easily removed from the base. On both sides of the switch, auxiliary contacts can be installed as needed to send signals indicating the opening and closing status of the switch.
