Broyce Control Earth Leakage Relay Frequency Range 50 to 400 Hz, 30A Leakage, SPDT SPNO Output ELRM44V-30 12-125V DC

Broyce Control ELRM44V-30 12-125V DC Earth Leakage Relay is engineered for precise detection of residual sinusoidal alternating and pulsating direct currents in electrical systems, suitable for industrial, automation, and electrical control settings operating within a frequency range of 50 to 400 Hz and capable of monitoring leakage currents up to 30A.

This relay operates with an adjustable trip level from 0.03 A to 30 A and a time delay adjustable from 0 to 10 seconds, allowing users to tailor protection parameters to specific installation requirements. The device trips when leakage current exceeds set thresholds, typically activating external switching devices such as contactors or shunt trips.

Equipped with SPDT and SPNO relay outputs, this model offers flexible connectivity options for control circuits. It includes local and optional remote test/reset buttons, enabling efficient maintenance and system verification without system interruptions. The isolated auxiliary supply ensures safe and reliable powering of the relay unit.

Designed for DIN Rail mounting, its compact 44 mm width, 85 mm height, and 44 mm length facilitate installation in standard control panels. The product conforms to international safety and EMC standards including IEC 61000-4-2, CE, IEC 60947, IEC 61543, CISPR 22, and others, ensuring reliability in demanding industrial environments.

Operating conditions span a temperature range of -20°C to 55°C with an IP20 ingress protection rating suitable for indoor electrical panels. The product originates from the United Kingdom, reflecting high manufacturing standards.
