Product Description
Broyce Control LPRA/2 400V Monitoring Relay is a microprocessor-based device designed for precise monitoring of three-phase electrical systems. It supports DPDT contact configuration and mounting on a DIN Rail, suitable for industrial control panels.
The relay performs true RMS measurement of voltages either phase-to-phase or phase-to-neutral, with selectable nominal voltages for 243 V and 540 V AC applications. This ensures accurate monitoring across common three-wire and four-wire supply systems.
This unit continuously monitors its own supply and detects phase asymmetry, phase sequence errors, phase loss, and neutral loss to prevent electrical faults. Adjustable asymmetry trip levels and time delay provide customizable protections tailored to specific industrial equipment requirements.
Designed with a compact 17.5 mm DIN Rail housing and utilizing screw terminal connections, the relay is easy to install and maintain. Visual indication with green and red LEDs communicates supply and relay status clearly to operators.
The relay is rated for 5A contact switching current with DPDT output contacts and is built with flame retardant materials compliant to UL94 VO standards. It operates reliably in ambient temperatures from -20°C to +60°C, making it suitable for a wide range of industrial, electrical, and automation applications.
Microprocessor based relay providing comprehensive phase monitoring. Wide voltage compatibility with selectable nominal voltages for flexibility. Detection of phase sequence, loss, and asymmetry conditions ensures equipment safety.
Compact and robust design optimizes panel space and installation convenience. Comprehensive IEC, EN, UL, and RoHS compliance ensures international standards conformance.
This monitoring relay is ideal for industrial, automation, electrical control, and process control applications demanding precise phase monitoring and fault detection. Its DIN Rail mount and microprocessor control make it a versatile solution for modern electrical panels.
