Crouzet Monitoring Relay 3 Phase 183 to 528 V AC Monitor Range SPDT DIN Rail Mount 208V AC 480V AC 84873022

Crouzet 84873022 Monitoring Relay is a 3 phase multifunction phase control relay that provides advanced monitoring for electrical networks. Designed to operate within a monitoring voltage range of 183 to 528 V AC, this relay ensures the proper sequence and presence of phases L1, L2, and L3. It detects issues such as total phase failure, undervoltage and overvoltage conditions, as well as asymmetry rates between phases, making it suitable for industrial and commercial electrical control systems.

Equipped with SPDT contact configuration and a plug-in type function, the relay supports DIN rail mounting for easy installation in electrical cabinets and control panels. The device uses true RMS measurements for accurate voltage monitoring and has LED indicators to provide clear fault signaling. If faults persist beyond the configured delay, the output relay switches and the LED disables, enabling prompt fault management.

This monitoring relay supports supply voltages of 208 V AC and 480 V AC and has a contact current rating of 5 A, with a switching voltage of up to 250 V AC/DC. It features terminal block connection type and protection ratings IP30 and IP20 for use in controlled environments. The compact form factor measures 92.6 mm in height, 69 mm in length, and 17.5 mm in width, fitting standard DIN rail assemblies.

The product complies with multiple international standards including CSA, IEC/EN 61000-6-4, IEC/EN 50178, GL, IEC/EN 61000-6-3, IEC/EN 61000-6-1, CE, UL, and RoHS, ensuring safety and environmental compliance. Manufactured in Indonesia, the Crouzet 84873022 Monitoring Relay is ideal for use in electrical automation, industrial machinery, HVAC controls, and other industrial network monitoring applications.

Monitors phase sequence, phase failure, undervoltage, overvoltage, and asymmetry rates accurately. True RMS measurement technology for reliable voltage monitoring. LED fault indication for intuitive status monitoring. Compact DIN rail mount design for convenient installation.
