Product descriptions from the supplier
Description

Pole Isolator Switches DNH8(HGL) series are designed for use in a variety of applications where circuit turn-on and turn-off or electrical isolation is required. They are available in seven different models, ranging from 63A to 3150A, and feature a modular design with three and four levels (three levels + neutral level for turn-on and turn-off).

Electrical isolation switch is also equipped with a front-side window that indicates the contact’s on/off state, and a rear observation window that allows for direct observation of the contact’s on-off state.

Temperature Range: The ambient air temperature should remain between -5 °C and +40 °C, with relative humidity not exceeding 95%.

Altitude: Installation altitude must not exceed 2000 meters.

Environment: The switch should be used in environments free from explosive hazards and where rain or snow does not intrude.
