EA9XN310

The Schneider Electric EA9XN310 is a voltage monitoring relay / under-voltage and over-voltage release from the Easy9 (EA9) range. It is designed to automatically disconnect an electrical circuit when the supply voltage falls below a set threshold (under-voltage) or rises above a set threshold (over-voltage), thereby protecting connected equipment from damage due to abnormal voltage conditions.

Parameter Specification Product Range / Series Easy9 (EA9) Model EA9XN310 Function Under-Voltage and Over-Voltage Release / Voltage Monitoring Relay Rated Supply Voltage (Us) 230V AC, 50/60 Hz (Single-phase) Monitoring Voltage Range Adjustable (typically covers a wide range around nominal voltage) Under-Voltage Trip Setting (U<) Adjustable (e.g., 70% to 100% of Un) Over-Voltage Trip Setting (U>) Adjustable (e.g., 100% to 130% of Un) Trip Delay Time Adjustable (e.g., 0.1s to 30s) to avoid nuisance tripping during short dips or surges. Reset Mode Automatic or manual (typically auto-reset after voltage returns to normal). Output Contact 1 changeover contact (SPDT) - Used to trip the shunt release coil of a compatible circuit breaker. Rated Operational Current (Ie) For the output contact (e.g., 6A AC-15). Mounting DIN Rail (35mm) Standards IEC/EN 60947-1, IEC/EN 60947-5-1 Operating Temperature -25°C to +55°C Protection Degree (IP) IP20 (when mounted in an enclosure)
