Function

A Type B residual current device (RCD) compliant with IEC 60947-2 Annex M detects and interrupts both alternating and direct leakage currents. It provides protection against complex residual current faults, including those from loads with DC components. This ensures enhanced safety in modern electrical installations with sensitive equipment.

Advantages

TRMS Triggering Accuracy

TRMS technology ensures precise detection of complex current leaks, preventing false tripping and ensuring reliable protection.

Fully Configurable

Easily configure the time delay (0,02...10s), leakage current (30mA to 10A), relay position (open or closed), and harmonic filters up to the 21th order.

Fast Identification of Malfunction Causes

The customization of harmonics is crucial thanks to configurable harmonic filters.
This allows for the rapid detection of the source of leakage current by analyzing specific harmonics.

Communication

Remotely monitor parameters via Modbus communication.
