A unique concept that dramatically reduces the wiring/installation time of multifunction power meters and current transformers.

These savings are made possible due to the innovative design of both the current transformers and the meters, which allow plug in connectors to be used for both current and voltage input/output. An RJ45 lead is used for connecting between the three phase current transformer and meter, and ‘readymade’ plug in leads are used for the voltage input.

The meters are provided with both input and output voltage connections which allow up to 32 meters to be daisy chained to a common supply voltage via the first meter. All our plug-in three phase current transformers have been designed with hole centres and apertures to fit most standard industrial circuit breakers.

Pluggable Meters

This system is safer than using traditional current transformers because plug-in transformers incorporate the resistive shunts usually located within the power meter. This means that the secondaries are always loaded, therefore eliminating the possibility of dangerously high voltages developing during open circuit conditions.
