The safety local isolator module features the same functions as a standard isolator module with an additional local safety function.

In the case of EMERGENCY STOP, the safety local isolator module switches the series-connected 400 V disconnecting module. This safely isolates the 400 V circuit up to CAT 4.

The 400 V disconnecting module can be used together with the safety local isolator module for local safety applications.

It contains two contactors connected in series for safety-oriented tripping of the main circuit. The auxiliary circuit supply of the device is via a safety power rail in the backplane bus module.
