Overvoltage & Undervoltage Protector, 63A

Informācija par preci

Over voltage and under Voltage protection relay, 63AFeatures:Overvoltage & Undervoltage Protector designed to protect single-phase electrical equipment against overvoltage, undervoltage, and overcurrent.Automatic overvoltage and undervoltage protection is suitable for single-phase 230V AC circuits with a rated operating current of up to 63A.It is a microprocessor-based voltage monitoring device for single-phase AC networks, designed to protect electrical equipment from damage.The device monitors the mains voltage and displays voltage and current values on a digital display.When overvoltage, undervoltage, or overcurrent occurs in the circuit, the relay quickly and reliably disconnects the circuit, and when the circuit voltage returns to normal, it automatically restores the power supply.The buttons allow setting the overvoltage, undervoltage, and overcurrent protection thresholds, their recovery values, as well as the action and recovery delay times.The power-on delay helps protect connected equipment from repeated voltage fluctuations that may occur while the mains supply is stabilizing.Compact design, reliable operation, and easy installation on a DIN rail.Both aluminium and copper conductors can be used for connection.Suitable for administrative, industrial, and residential buildings, electrical distribution boards, and industrial machinery where continuous voltage and current monitoring is required.Note: the relay protects against prolonged mains voltage fluctuations but is not specifically designed to protect against short impulse overvoltages caused by lightning. Surge protection devices (SPD) are intended for this purpose.Main functions:1. Overvoltage protection.2. Undervoltage protection.3. Overcurrent protection.4. Automatic recovery.5.
