Description

Isolating Switch DNH8(HGL)/H Series

Operation Behind The Cabinet – Load Disconnector

Scope of Application

Isolating Switches with a current capacity of 160 to 1600 Amperes are suitable for use in circuits for making and breaking connections, as well as for electrical isolation. Switches with a rated current of 1000 Amperes or more are only to be used for electrical isolation. Three-pole and four-pole (3+1) switches are available.

Switches rated 1600 Amperes or less are available with an observation window, through which the state of the contacts (open or closed) can be directly observed.

Auxiliary contacts can be fitted if required.

Note: This Isolating Switch product only provides operation outside the cabinet

Order model: DNH8 (HGL) -630/3JH

If a visual observation window is required, the Isolating Switch order model is DNH8 (HGL) -630/3JKH
