Chint HK18-63/2E Photovoltaic Solar Knife Disconnector Switch

Chint HK18-63/2E is a disconnector in the HK18 series of Chint, which is described as follows:

Basic parameters: rated frequency is AC 50/60Hz, working voltage is single-phase 220V or three-phase 415V, rated working current is 63A, rated insulation voltage is 800V, and the number of poles is 2 poles.

Functional use: It is suitable for photovoltaic, household electrical equipment and industrial enterprise power distribution systems. It can be used for frequent manual connection and disconnection of circuits, and can also play the role of isolating circuits to provide safety protection for circuit maintenance and other operations. However, it is generally not used to directly start and disconnect a single motor.

Standard compliance: It complies with GB/T 14048.3 and IEC 60947-3 standards. The product quality and performance meet the requirements of relevant national standards and International Electrotechnical Commission standards.

Working environment: The ambient air temperature does not exceed + 70℃, not lower than - 25℃, and the average temperature value within 24h does not exceed + 35℃. The installation site altitude should not exceed 2000m. If it is within 5000m, the capacity can be reduced. When it is higher than 2000m, the capacity should be reduced by 5% for every 1000m. When the maximum temperature is + 60℃, the relative humidity of the air should not exceed 95%, and there should be no gas and dust in the medium that can corrode metal and damage insulation. The surrounding environmental pollution level is level 3.
