Overview
The HUH1 Series Load Switch (hereinafter referred to as “switch”) is suitable for industrial and commercial power distribution equipment with AC 50 Hz, rated voltage up to 690 V and conventional thermal current up to 3,200 A, and used for infrequent making and breaking circuits and galvanic isolation (above 1,000 A is only for galvanic isolation). The switch is widely applied to power distribution systems and automation systems of the construction, electric power, petrochemical industry and other industries.
The HUH1/C Side Operation Load Switch is equipped with an additional side operation mechanism on the basis of the front central operation load switch of the HUH1, which is suitable for the making/breaking circuit of the side operation and galvanic isolation.
The HUH1/Z Double-throw Switch Load Switch is composed of two HUH1 Load Switches stacked up and down or assembled side by side in the left-right direction. It is suitable for the switching of two-way power supply or the switching and safety isolation of two load devices.
The switch is beautiful in shape, novel and concise, simple in structure and easy to operate.
It complies with IEC60947-3 and GB/T14048.3.
Normal working conditions
1. Ambient air temperature: The temperature shall not be higher than +40°C or lower than -5°C, and the average value within 24 hours shall not exceed +35°C.
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. Contamination grade of the surrounding environment: Grade 3.
5. Installation category: III, IV.
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 and destroy the insulation.
7. Please consult with our company for the use occasions under abNormal working conditions.
