YCHR8 Fuse-type Isolation Switch

YCHR8 series fuse-type isolating switches works with NH00 and NH01 type fuses. Has aworking voltage range of 0-500V DC and 0-690V AC with a maximum current of 800A. The working current varies according to size of fuse used.

Product Details

Features

• UPS for the power supply of computers and servers

• Telecommunication power supply

• Metering and lighting module applications

• Switchboards

• Capacitor banks

• General fuse for power supply networks

• Power supply and generation fuse protection

Operating condition

1. The ambient air temperature should not be higher than +50°C and not lower than -5°C.

2. Humidity: When the maximum temperature is +50°C, the relative humidity of the air does not exceed 50%. Higher relative humidity is allowed at lower temperatures, such as 90% at 20°C.Special measures should be taken against occasional condensation due to temperature changes.

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

4. The switch should be installed in a place without significant vibration away from hazardous and flammable materials.

5. Has an IP30 rating when closed and IP20 rating when open.
