This protection relay monitors voltage and current in single-phase 230 V AC circuits with an operating current of up to 63 A. It disconnects the circuit during overvoltage, undervoltage or overcurrent and automatically restores power when the voltage returns to normal.

Adjustable protection and delays

Protection settings: buttons let you adjust voltage and current protection thresholds and their recovery values.
Timing: the action time is adjustable from 0.1–30 s, with recovery and power-on delays of 1–500 s.
Monitoring: a digital display shows voltage and current readings.
Manual control: the protection function can be switched on or off.

The power-on delay helps protect connected equipment from repeated voltage fluctuations while the mains supply stabilises.

Installation and protection limits

The relay mounts on a DIN rail and accepts aluminium or copper conductors. It is suitable for distribution boards, administrative, industrial and residential buildings, and industrial machinery requiring continuous voltage and current monitoring.

Important: this relay protects against prolonged mains voltage fluctuations but is not specifically designed for short impulse overvoltages caused by lightning. Surge protection devices (SPD) are intended for that purpose.

Does this relay replace lightning surge protection?

No. It protects against prolonged mains voltage fluctuations, not short impulse overvoltages caused by lightning. Surge protection devices (SPD) are intended for those impulses.

Does power return automatically?

Yes. The relay automatically restores power when the voltage returns to normal. The recovery delay can be set from 1–500 s.
