Single Phase Overvoltage Protection Relay 35mm Din rail Mounting For Refrigeration

Monitor for overvoltages and undervoltages simultaneously. Separate settings and outputs supported for overvoltages and undervoltages. Manual resetting and automatically resetting supported by one. Pre-alarm Monitoring Mode. Two SPDT output relays, 5 A at 250 VAC (resistive load). Output status can be monitored using LCD indicator.

When the over-voltage and under-voltage in the line exceed the specified value, it can be automatically disconnected, and can automatically detect the line voltage, and can automatically close the device when the voltage in the line returns to normal. Mainly used in home and shopping malls distribution (single-phase AC230V, three-phase four-wire AC415V) line as over-voltage, under-voltage, phase failure, zero line protection.

The self-repair over/under voltage protector is applicable to users or loads with single-phase AC voltage 220V, frequency 50Hz, rated operating current of 6A and below. Single-phase line over-voltage caused by neutral fault protection for single-phase consumer equipment. Mainly used for the protection of the distribution line of the residential household box or the need to protect the single-phase electricity equipment
