Chint HK18 series Photovoltaic Solar Knife Disconnector Switch

Chint HK18 series is a disconnector, mainly used in photovoltaic, household appliances and industrial enterprise power distribution systems. It can frequently manually connect and disconnect circuits and isolate circuits, but is generally not used to directly start and disconnect a single motor. The relevant introduction is as follows:

Rated frequency: AC 50/60Hz.

Working voltage: single-phase 220V, three-phase 415V.

Working current: up to 63A.

Rated insulation voltage: 800V.

Meets standards: GB/T 14048.3, IEC 60947-3.

Common model of Chint HK18 series

The following is a description of Chint HK18 series, which is usually a special disconnector for new energy:

HK18-□/2E series (2-pole, single-phase scenario)

HK18-16/2E

Rated current 16A, 2-pole design, suitable for 220V single-phase circuit, commonly used for circuit isolation of photovoltaic systems or household power distribution.

HK18-32/2E

Rated current 32A, 2 poles, can carry larger single-phase loads, suitable for power disconnection of small commercial or industrial equipment.

HK18-63/2E

Rated current 63A, 2 poles, the series of high current specifications, suitable for circuit disconnection and isolation of high-power single-phase equipment.

HK18-□/3E series (3 poles, three-phase scenario)

HK18-16/3E

Rated current 16A, 3 pole design, suitable for three-phase 380V/415V circuits (such as small three-phase motors, photovoltaic inverters, etc.), supports manual disconnection of three-phase power supply.

HK18-32/3E

Rated current 32A, 3 poles, suitable for medium-power three-phase equipment, such as industrial control distribution boxes, small three-phase power systems.

HK18-63/3E

Rated current 63A, 3 poles, a three-phase high current model, commonly used for photovoltaic combiner boxes, power isolation of large three-phase equipment, and supports frequent manual operation.
