3UG4625-2CW30 SIEMENS

The 3UG4625-2CW30 is a digital monitoring relay designed for precise residual current monitoring, ensuring electrical safety and preventing equipment damage. It operates in conjunction with a 3UL23 current transformer to accurately measure leakage currents. The relay features independently adjustable setting ranges from 0.03 to 40 A for both warning thresholds and switch-off values, providing flexibility in configuring protection parameters. It supports a wide supply voltage range of 24 to 240 V AC/DC at 50 to 60 Hz, making it suitable for various power systems. The adjustable ON delay and tripping delay, ranging from 0.1 to 20 seconds, allow for customized response times to avoid nuisance tripping. Shutdown hysteresis is adjustable up to 50%, while the warning hysteresis is fixed at 5%, ensuring reliable operation and minimizing chattering. With a narrow width of 22.5 mm, the relay saves valuable panel space. It is equipped with two change-over contacts that can be configured with or without a fault buffer for enhanced control and indication. The spring-type connection system simplifies wiring and ensures secure connections.
