With a residual current monitoring module of the EV-RCM series, AC and DC residual currents can be detected with a measuring sensor in accordance with the requirements of IEC 62752. In combination with a type A residual current device, the module saves you from having to use an expensive type B residual current device because it interrupts the charging process in the event of an error.

Your advantages:

  • Increased availability and service life of charging points, thanks to continuous residual current monitoring
  • Universal residual current detection with just one measuring transducer
  • Use and continued operation of a cost-effective type-A residual current device
  • Convenient state monitoring and automatic reset in the event of errors (in combination with Phoenix Contact charging controllers)

Single-channel residual current monitoring module

Single-channel RCM module for residual current monitoring of a charging point  

Single-channel residual current monitoring module

The single-channel EV RCM Basic module with one measuring sensor is specifically designed for a single charging point. In conjunction with type A residual current safety devices, this version is ideal for use in simple charging points for home use.

Application example: Charging station for home use

Setup of a wall box with residual current monitoring

A home charging station can detect residual currents using a single-channel RCM module and use this information to shut off the charging point. This ensures the long-term durability of a compact charging point for home use.

Two-channel residual current monitoring module

Two-channel RCM module for residual current monitoring of two separate charging points  

Two-channel residual current monitoring module

The two-channel EV RCM Compact module is used for universal residual current detection for two separate charging points in one charging station. The separate monitoring using two measuring sensors increases the availability of charging points in a commercial environment. Save space and money thanks to separate signal evaluation in one RCM unit.

Application example: Commercial charging points

Charging infrastructure with two-channel RCM module

A two-channel RCM module provides the option of monitoring two separate charging points within a charging station separately from each for potential residual currents. Operators of commercial charging infrastructures thus benefit from increased availability.

Advantages in combination with Phoenix Contact charging controllers

EVCC Basic and EVCC Advanced charging controllers  

EVCC Basic and EVCC Advanced charging controllers

Connecting the RCM modules to the EV Charge Control Basic or EV Charge Control Advanced charging controllers from Phoenix Contact enables convenient state monitoring as well as automatic resetting as soon as the residual current is no longer present.

As a result, you avoid costly servicing and ensure that the charging point is immediately available again for further charging processes. Furthermore, you achieve the required protection against electric shock when charging electric vehicles in accordance with IEC 61851-1 and DIN VDE 0100-722.
