Overview

The HR6 Series Fuse Disconnecting Switch (hereinafter referred to as “switch”) is designed by our company with reference to the products of AEG, Germany, which is suitable for the distribution circuits and motor circuits with high short-circuit current with AC 50 Hz, rated voltage of 400 V and 690 V and conventional thermal current up to 1,000 A. This product is used as the power switch, disconnecting switch and emergency switch that are not frequently operated manually, and for the short-circuit protection, but generally not used to directly switch on and off a single motor.

The switch is simple in structure and easy to operate. It complies with IEC60947-3 and GB/T14048.3 and is the best choice among similar products.

Normal Operating Conditions

2. Altitude: The altitude of the installation location shall not exceed 2,000 meters.

3. Relative humidity: The relative atmospheric humidity shall not exceed 50% when the maximum ambient temperature is +40°C, and a higher relative humidity is allowed at a lower temperature (for example: 90% humidity at +20°C), but the occasional condensation on the switch surface due to temperature changes shall be considered.

4. The contamination grade of the surrounding environment is Grade 3.

5. Installation category: III.

6. Installation conditions: The switch shall be installed vertically in a place without significant shaking, impact or vibration and in a medium without explosion risks, or enough gas or dust to corrode metals or destroy the insulation.
