insulation monitoring relay for non-grounded (IT) networks-3UG4583-1CW31

Product Description

Siemens SIRIUS Insulation Monitoring Relay for Non-Grounded (IT) Networks – 3UG4583-1CW31

The Siemens 3UG4583-1CW31 is a high-performance SIRIUS insulation monitoring relay designed for continuous monitoring of non-grounded (IT) electrical networks. It detects insulation faults at an early stage, helping prevent equipment damage, unexpected downtime, and electrical hazards in industrial power systems.

This relay supports monitoring of AC and DC IT networks up to 400 V AC and 600 V DC with a measuring range of 1–100 kΩ / 2–200 kΩ. It features adjustable response values, fault memory, wide-range AC/DC supply voltage, and changeover relay outputs for reliable alarm and protection switching. The compact 45 mm DIN rail mounting design makes it ideal for industrial control panels, automation systems, hospitals, process plants, mining applications, and critical power systems.
