CNC jännite- ja virtavalvontarele, 63 A

Digital voltage and current control relay used for protection of single-phase electrical equipment against overvoltage, undervoltage or overcurrent.

Automatic protection against overvoltage and undervoltage suitable for single-phase AC 230V circuits with rated operating current not exceeding 63A.

Microprocessor-based single-phase AC mains voltage monitoring device designed to protect electrical equipment from damage.

The device analyzes the mains voltage and displays voltage and current values on a digital indicator.

When overvoltage, undervoltage or overcurrent problems occur in the circuit, the relay quickly and reliably disconnects the circuit, and when the circuit voltage returns to normal, it automatically restores power.

Buttons allow setting overvoltage, undervoltage and overcurrent protection limits, their recovery values, and tripping and recovery delay times.

Relay switch-on delay protects connected devices from repeated voltage fluctuations that may occur while the network stabilizes.

• Compact design, reliable operation, easy installation on DIN rail.
• Aluminum and copper wires can be used for connection.

Suitable for administrative, industrial and residential buildings; in electrical panels and industrial machines where continuous voltage and current monitoring is important.

• Note: the relay protects against long-term mains voltage fluctuations, but is not specifically designed to protect against short impulse overvoltages caused by lightning. Surge protective devices (SPD) are intended for that.
