Description

The disconnect switch is made up to two units — the basic switch and the operatingmechanism. These two units must be properly combined with a connecting bar toobtain a functional device. This method allows the user to determine specificdistances required between the disconnect switch and the operating mechanism.This feature is often required when the enclosure is to be mounted high off the floormaking a conventional device difficult for personnel to operate. Note: The operatingmechanism can only be mounted below the switch.

Conformity to Standards:Your order must include:• Cat. No. of the disconnect switch
