residual current monitoring relay-3UG4625-1CW30

Product Description

Siemens SIRIUS Residual Current Monitoring Relay – 3UG4625-1CW30

The Siemens 3UG4625-1CW30 is a digital residual current monitoring relay from the SIRIUS 3UG4 series, designed for continuous monitoring of leakage and residual currents in industrial electrical systems. Used together with Siemens 3UL23 residual current transformers, this relay helps detect insulation faults and leakage currents at an early stage, improving electrical safety and preventing equipment damage, fire hazards, and unexpected downtime.

This compact DIN rail mounted relay supports adjustable warning and trip thresholds from 0.03 A to 40 A, making it suitable for industrial automation systems, power distribution networks, motor circuits, process plants, and critical electrical infrastructure. It features adjustable ON-delay and tripping delay times, shutdown hysteresis settings, fault memory function, and dual changeover relay outputs for dependable alarm and protection control.
