The isolator module with integrated group fusing function (i.e. additional group short-circuit protection for all subsequently supplied motor starters) and switch disconnector function is used for safe disconnection of the 400 V operational voltage in the plant.

Depending on the power distribution concept, all stations can be equipped with an isolator module as an option.

The following properties apply to the isolator module:

• Increase of plant availability through fast replacement of units (easy mounting and plug-in technology)
• Cabinet-free design thanks to high degree of protection IP65

The isolator module is available in addition in a safety version (see page 9/10 "Safety local Isolator Modules").
