Broyce Control Monitoring Relay, 3 Phase, SPDT Contact, DIN Rail Mount, 243V AC / 540V AC LPRC/2 400V

Broyce Control LPRC/2 400V monitoring relay is a microprocessor-based device designed for precise three-phase electrical system monitoring in industrial and commercial environments. The relay measures true RMS phase-to-phase (3-wire) or phase-to-neutral (4-wire) voltages, providing protection against phase failure, phase sequence errors, as well as under and over voltage conditions with adjustable time delay.

Housed in a compact 17.5 mm-wide enclosure suitable for DIN Rail mounting, the device is engineered to fit seamlessly within control panels. It features screw terminal connections and an IP20 rating, offering adequate protection in indoor electrical cabinets.

The relay supports selectable nominal voltages of 243V and 540V AC, making it compatible with a variety of three-phase supply systems. It provides two independent SPDT relay outputs rated at 5A each, allowing simultaneous monitoring and control for under voltage and over voltage conditions.

Visual status indicators include a green LED for supply presence and separate red LEDs for each relay output state, enhancing user feedback and facilitating troubleshooting. The relay is rated for an electrical life of over 150,000 operations, reflecting its durability under frequent switching.

Operating temperature ranges from -20°C to +60°C allow its use across typical industrial settings. Compliance with multiple international standards such as EN 61000-6-2 immunity, IEC 60947-1, RoHS environmental directives, CE marking, IEC 60664 insulation coordination, and UL safety certification guarantee the product's reliability and safety.

This monitoring relay is well suited for industrial automation, electrical panels, manufacturing equipment, and process control applications. It safeguards electrical systems by timely detecting electrical faults and allowing protective measures to be enacted.

For system integrators and electrical professionals seeking a dependable phase monitoring solution, the Broyce Control LPRC/2 400V relay offers a robust and accurate choice for enhanced system protection and operational reliability.
