RS PRO Three Phase Monitoring Relay SPDT DIN Rail Mount 280V AC to 520V AC 8A Contact Current 102-6135

RS PRO 102-6135 is a high-precision three-phase monitoring relay specifically engineered to protect electrical equipment by monitoring undervoltage conditions across three phases. This device employs advanced microprocessor technology to continuously measure phase-to-phase voltage levels, breaking circuit connection when voltages fall below preset thresholds.

Designed for DIN rail mounting, the relay supports a maximum sensing range of 280V AC with a supply voltage capability from 280V AC to 520V AC. It incorporates a single pole double throw (SPDT) contact configuration rated for 8A contact current, providing reliable switching performance in demanding industrial environments.

The relay also features a fixed time delay of 100 milliseconds that prevents nuisance tripping caused by brief voltage dips, enhancing system stability. Two integrated LEDs provide clear operational status indications including phase loss, incorrect phase sequence, and undervoltage alerts.

Compact dimensions of 66.5 mm (length) x 17.5 mm (width) x 89 mm (height) ensure efficient space utilization within control panels and electrical enclosures. The relay operates efficiently in temperatures ranging from -20°C up to +60°C, making it suitable for various industrial and commercial applications.

Additional features include true RMS monitoring for high measurement accuracy, compliance with electromagnetic compatibility standards (EMC), and adherence to IEC and EN regulations ensuring quality and safety.

This monitoring relay finds wide application in industrial automation, electrical control, manufacturing plants, and power distribution systems where phase and voltage monitoring is critical for equipment protection and fault prevention.

The relay monitors phase-to-phase voltages ensuring safe operation within a maximum 280V range. Equipped with SPDT contact configuration capable of handling 8A contact current. Adjustable time delay of 100 ms to prevent nuisance tripping during short voltage dips.
