Overview

VigiPacT is a complete range providing earth-fault protection for all types of AC installations, including power distribution, sub-distribution, and industrial control systems. VigiPacT devices operate on TT, TNS, and IT systems for protection of persons against direct contact. The relays are type A and type AC as defined by standard IEC/EN 60947-2 (annex M).

The VigiPacT RMH relay is used with the VigiPacT RM12T multiplexer to monitor up to 12 independent circuits.

The device allows to:

• monitor the earth-leakage current.

• helps to identify the insulation faults before they become hazardous for life and property.
