Device description

Terminal Cover

Protective accessory that covers live terminal parts and reduces the risk of accidental touch or short circuit.

A terminal cover is installed on a compatible electrical device or terminal assembly to shield exposed live parts.

It improves service safety, reduces the risk of accidental contact by tools or conductive objects and may help maintain the required degree of protection.

Cover design depends on the device series, number of poles, terminal type and conductor-entry direction.

Selection criteria include device compatibility, number of protected poles, service access to terminals after installation, material and environmental conditions.

Components in this subcategory

Terminal covers for breakers, switches, contactors and other electrical devices.
