Isolators incorporate diagnostics

A Rittal product story
Edited by the Engineeringtalk editorial team Dec 12, 2007

On-load isolators provide safe, reliable isolation protection for downstream electrical equipment.

Rittal RiLine NH on-load isolators provide safe, reliable isolation protection for downstream electrical equipment.

Available either with or without fuse monitoring, the isolators range from 100 to 630A (60mm), sizes 000 to 3 and can be easily mounted directly onto Rittal's range of busbar systems.

Using either electronic or electromechanical fuse monitoring allows quick fault diagnostics.

If a fuse blows, a signal is immediately sent to advise of the need for quick replacement without effecting plant availability.

The fitting of a microswitch indicates the switching position of the isolator lid to the control desk/room.

The cable outlet may also be swapped from the top to the bottom using the same device thereby cutting warehouse costs by up to 50%.

To prevent unintentional opening of the isolator lid, all designs have a screwdriver-operated lock as standard; the lock position may also be sealed with sealing wire if preferred.

A sliding window incorporated into the isolator lid contains a unique spring mechanism, which automatically closes the holes after voltage testing.
