Discover Acti9 Vigi NG125

Immune to disturbances and easy to install:

Acti9 Vigi NG125 is the add-on residual current device designed specifically to work with Acti9 NG125 miniature circuit breakers up to 125A.

It complies with IEC/EN61009-2-1 standard to offer the following earth leakage protection functions:

  • Protection of people against electric shocks by direct contact (30mA).

  • Protection of people against electric shocks by indirect contact (300mA).

  • Protection of installations against risks of fire (300mA)..

Benefits of Acti9 Vigi NG125

Modular & flexible

  • Improved flexibility of rating selection vs RCBOs.

  • Lower cost of installation due to cascading tables for NG125 MCB.

  • On-product adjustable settings:- Tripping sensitivity from 30mA to 3A.

  • Tripping time from instantaneous to selective and delayed.

  • Pre-Alarm thresholds can be set as a percentage of Idn.

Easy Installation

  • Foolproof design to ensure that the right Vigi add-on block is fitted with the right NG125 MCB.

  • Plug-in system of QuickVigi that removes the need to screw at the terminals.

  • Easy to remove from DIN rail without unwiring.

Ease of operation

  • Wide range of indicating and actuating auxiliaries for remote control and monitoring.

  • Earth fault indication by LED on product front face or remotely.

  • Pushbutton for disconnection to allow for dielectric test.

  • Easy to remove from DIN rail without unwiring.

Enhanced safety and Service Continuity

  • Its Super Immune technology (-SI) associated with a protection class Type A will limit nuisance tripping and non-tripping in harsh electromagnetic conditions and polluted atmospheres.

  • Pre-defined threshold of the alarm will monitor the earth leakage levels of your installation to prevent possible tripping thus improving the continuity of service.
