Residual-current devices for different types of power distribution systems

Part of Pact Series

Vigirex residual current relays with associated toroids provide full protection and monitoring against earth-leakage current to ensure people and property are safe.

  • Features

    Vigirex relays with associated toroid sensors measure the leakage current in an electrical installation to detect levels that may be damaging. Ideal for protection or alarming, the products offer multiple setting and mounting possibilities. All options are available in two models (M & P):
          •Modular (M) devices, mount on standard 35 mm DIN rails
          •Panel (P) model, mount in cut-outs on front doors, or front plates (72 x 72 mm) using integral mounting clips
         •For use on low-voltage AC installations up to 1000 V, and for TT or TN neutral networks
         •Currents up to 3200 A (depending on sensor)
            - Closed Toroid – widest range
            - Split (Open) Toroid – install without disconnecting existing cable
            - Rectangular sensors – for large bus bars & high currents 

        •Sensitivities from 30 mA to 30 A (with time delay range from 0 to 4.5 s)
        •Applications with frequencies up to 400 Hz
        •Immunity to nuisance tripping (tolerance between 0.8 –1 x I ∆n)
        •Operation guaranteed in less than 40 ms
        •Overvoltage category IV
        •Modbus communication (RHU & RMH)
        •Compliance with standards:
             - International: UL 1053, CSA C22.2 N° 144 and IEC 60947-2 annex M
             - Regional: CE, EAC and CCC marking
