The WARB5100C/PME40RSP is a 3 phase PME fault detection unit with a 40A RCBO and Type 2 SPD for one compatible three-phase EV charge point. It combines a 5-pole 100A MCB, PME monitoring, a factory-fitted 40A RCBO and surge protection in one pre-wired IP40 enclosure.

This is the most fully equipped of the four currently documented WARB configurations. The exact RCBO characteristics and suitability for the selected charger must still be confirmed from the supplied device and manufacturer documentation.

Installer Tip: Choose this version when the verified design requires both the fitted 40A RCBO and local Type 2 surge protection. If the SPD is coordinated elsewhere, compare the WARB5100C/PME40R.

Key Features

  • For one three-phase EV charge point
  • 5-pole 100A MCB with integrated PME relay arrangement
  • Factory-fitted 40A RCBO
  • Factory-fitted Type 2 SPD
  • 400/415V supply monitoring
  • Linked disconnection of live, neutral and protective conductor

How the PME Monitoring Works

The unit monitors the three-phase supply against the manufacturer’s stated voltage thresholds. If any phase falls below 207V or rises above 253V under the specified fault conditions, the linked switching arrangement disconnects live, neutral and the protective conductor.

Under-voltage recovery is automatic when the supply returns to the normal operating range. Following an over-voltage operation, the unit requires manual reset in accordance with the manufacturer’s instructions.

Final selection must be based on the charger, supply, fault level, earthing arrangement and required residual-current and surge protection. Installation and verification must be completed by a suitably qualified person to the current edition of BS 7671.
