🔹 Digital Line Monitoring Relay with Neutral Loss Protection, 3-Phase 3-Wire/4-Wire, 35mm Module – 7UG0814-1CA20

🔹 Product Description

The Siemens 7UG0814-1CA20 is a digital line monitoring relay designed for comprehensive protection and monitoring of 3-phase 3-wire and 3-phase 4-wire electrical systems. Engineered for industrial and commercial applications, this intelligent relay continuously supervises critical network parameters to help prevent equipment damage caused by power supply abnormalities.

A key feature of this relay is its neutral loss protection capability, which helps detect neutral conductor failures and abnormal voltage conditions that can adversely affect motors, drives, control panels, and sensitive electrical equipment.

The relay monitors important electrical conditions including phase failure, phase sequence, phase asymmetry, overvoltage, undervoltage, and neutral loss, ensuring reliable operation of power distribution systems. Its digital design provides accurate measurements, adjustable settings, and dependable fault detection.

With a compact 35 mm DIN rail-mounted housing, the 7UG0814-1CA20 is ideal for installation in motor control centers (MCCs), power distribution panels, process automation systems, commercial buildings, and industrial switchgear.

The Siemens 7UG series is recognized for advanced monitoring capabilities, easy configuration, and long-term operational reliability in demanding electrical environments.
