Product Positioning

The 3UG4625-1CW30 is a Siemens SIRIUS series three-phase leakage current (ground fault) monitoring relay. It comes with a 3UL23 current transformer and can set two threshold values for warning and tripping, making it suitable for ground fault protection applications in three-phase power supply systems.

Core Product Advantages and Features

Included current transformer

The product comes with a 3UL23 current transformer, with a setting range of 0.03 to 40 amps, and can measure currents from 10 mA to 43 amps.

Two-stage lag setting

It provides a fixed 5% warning hysteresis and a maximum 50% trip hysteresis, which can be used to respond to two control logics: warning and trip.

Dual-group switching contacts

Equipped with two sets of switching contacts, it can simultaneously output warning signals and trip signals to meet the requirements of graded protection.

Three-phase power supply application design

Designed specifically for monitoring grounding faults in three-phase power systems, it features screw terminal wiring for convenient construction and maintenance.
