Broyce Control Monitoring Relay 3 Phase DPDT Screw Terminal DIN Rail Mount 243 → 540 V AC LPRT/2 400V

Broyce Control LPRT/2 400V monitoring relay is a microprocessor-based, compact DIN rail mounted device specifically engineered for three phase electrical systems. It offers precise voltage monitoring across a range of 243 to 540 V AC, suitable for industrial automation, electrical panels, and signal conditioning tasks. The relay ensures reliable phase failure, phase sequence, and under voltage protection, contributing to system safety and longevity.

This model features a dual pole double throw (DPDT) relay output rated at 5 A, driven by true R.M.S. voltage measurement for accurate phase-to-phase or phase-to-neutral monitoring. Its selectable nominal voltages allow flexible integration with standard 3-wire or 4-wire power supplies. The relay monitors its own supply voltage and triggers alarms on under voltage conditions, phase loss, or incorrect phase sequence, with adjustable trip level and time delay options to customize protection settings.

The unit's compact 17.5 mm DIN rail enclosure facilitates space-saving installations in control panels or switchboards. Screw terminals ensure secure and durable electrical connections. Status indicators include green LEDs for power supply and red LEDs for relay status, providing immediate visual diagnostics.

Suitable for use in industrial environments with operating temperature up to 60°C, the relay housing is constructed from flame retardant material certified to UL94 VO standards. The product meets international safety and immunity standards including UL, CE, IEC 60947-1, EN 61000-6-2, EN 61000-6-4, IEC 60664, and RoHS compliance for environmental safety.

This Monitoring Relay finds application in industrial electrical systems, automation controls, manufacturing plants, and any commercial installations requiring reliable three phase voltage supervision and protection.

The relay includes features for phase failure, phase sequence, under voltage detection, and time delay adjustments. Compact DIN rail mount design saves panel space and eases installation. True R.M.S. voltage sensing provides precise monitoring for three phase and neutral configurations.
