Checking for live stock

The Broyce Control LXPRT‑4W is a DIN‑rail mounted phase and voltage monitoring relay designed to safeguard three‑phase 4‑wire systems by detecting under‑voltage, over‑voltage, phase loss and incorrect phase sequence conditions. It features an actual RMS measuring circuit, adjustable trip thresholds (under‑voltage 75‑95 % of nominal; over‑voltage 105‑125 %) and a time delay of 0.2–10 s for fault filtering. Equipped with a single SPDT relay output rated at 8 A at 250 V AC, it operates from a supply voltage of 230 V (or 400 V variant) and is housed in a slim 17.5 mm-wide module for compact panel installations.

Crucial Features and Benefits of Choosing the Broyce Control 1-Phase, Voltage Monitoring Relay

Monitors three‑phase 4‑wire supply and detects phase loss and sequence errors.
Adjustable under‑voltage trip level: 75‑95 % of nominal supply.
Adjustable over‑voltage trip level: 105‑125 % of nominal supply.
Time delay range 0.2–10 s to suppress transient faults and ensure stable operation.
Single SPDT relay output rated 8 A at 250 V AC allows direct control of contactors or alarms.
Slim DIN‑rail housing (17.5 mm) for efficient integration into control panels.

Engineered for Robust Electrical Protection

The LXPRT‑4W is built to provide reliable protection in motor control centres, distribution boards, and industrial panels where three‑phase integrity is critical. With user‑adjustable thresholds and delays, engineers can tailor the device to system tolerance levels, enabling preventive interruption of loads before failure. The SPDT output allows direct interfacing with external switching devices, simplifying integration into safety or monitoring circuits.

Broad Range Application

Monitoring and protection of three‑phase mains feeding industrial motors.
Phase‑sequence and phase‑loss detection in control panels and automation systems.
Protection of pumps, compressors and HVAC systems prone to voltage fluctuation.
Integration into machine‑tool control cabinets to guard against under‑voltage stall conditions.
Retro‑fitting into existing switchgear for enhanced phase monitoring without major redesign.
