Chint HK18-16/2E Photovoltaic Solar Knife Disconnector Switch

Chint HK18-16/2E is a disconnector of Chint's HK18 series, which is mainly used in photovoltaic, household electrical and industrial power-distribution systems. The following is a detailed introduction:

Electrical parameters: The rated frequency is 50/60Hz, and the working voltage is 220V for single - phase or 415V for three - phase. The rated working current is 16A, and the rated insulation voltage is 800V. It has 2 poles.

Function and characteristics: It can be used for frequent manual connection and disconnection of circuits, and can also realize circuit isolation, providing a safe guarantee for circuit maintenance and other operations. However, it is generally not used to directly start and stop a single motor.

Compliant standards: It complies with GB/T 14048.3 and IEC 60947 - 3 standards, and the product quality and performance meet the requirements of relevant national and international standards.

Working environment: The ambient air temperature does not exceed +70℃, and is not lower than -25℃, and the average temperature within 24h does not exceed +35℃. The altitude of the installation site does not exceed 2000m, but it can be used with derating within 5000m. For every 1000m above 2000m, the capacity is reduced by 5%. When the highest temperature is +60℃, the relative humidity of the air does not exceed 95%, and the medium should be free of gases and dust that can corrode metals and damage insulation.
