Crouzet 3 Phase Monitoring Relay DPDT DIN Rail Mount 220V AC, 480V AC 84873220

Crouzet 84873220 is a high-precision 3 Phase Monitoring Relay with DPDT contact configuration and DIN rail mounting, designed to ensure safe and reliable voltage control for industrial and commercial electrical systems. It supports supply voltages of 220V and 480V AC and provides true RMS measurements for accurate voltage monitoring.

This relay monitors critical voltage parameters including undervoltage adjustable between -2% and -20% of the nominal undervoltage and overvoltage adjustable from 2% to 20%. It signals faults through distinct LED indicators that separately show overvoltage and undervoltage conditions.

The product is constructed to mount conveniently on a DIN rail using screw terminals, providing easy installation and secure connections within electrical panels. Certified with RoHS compliance, it meets industrial standards for environmental safety.

Engineered for rugged industrial environments, the relay supports operation within temperatures from -50°C to +50°C, and offers IP30 and IP20 protection ratings to guard against ingress of solid particles while allowing for ventilation.

The compact relay measures 69mm in length, 92.6mm height, and 35mm in width, making it suitable for installation in confined spaces. The H3US series model ensures detection of voltage faults and absence of neutral presence for precise three-phase network monitoring.

This monitoring relay is ideal for electrical automation, industrial monitoring, power distribution, and control applications in manufacturing plants, HVAC systems, and water treatment facilities. Its reliable and precise voltage monitoring helps prevent equipment damage and ensures operational continuity.
