Compact adjustable overvoltage, undervoltage and overcurrent protector for single phase 230VAC circuits. Designed for DIN rail installation, it isolates load circuits when voltage or current move outside set limits, helping protect motors, inverters, pumps, lighting and other electrical equipment. Key benefits Protects connected equipment by cutting power when overvoltage, undervoltage or overcurrent conditions occur. Flexible settings let installers match protection to the application for better compatibility and reduced nuisance trips. Compact DIN rail module saves panel space and installs quickly.

Why choose this protector Adjustable thresholds and delays let you tune protection to sensitive electronics or to tolerate temporary disturbances. Long service life and low power draw make it suitable for continuous panel installation. DIN rail form factor integrates easily into standard control and distribution boards. Typical applications Residential and commercial distribution panels to protect air conditioners, refrigerators, and motors from harmful voltage swings. Industrial control panels to protect drives, relays and PLCs from overcurrent and supply voltage faults. Solar inverter and battery system protection where overvoltage or undervoltage events can damage inverters and charge controllers. Package contents 1 x Protector Notes Select the 40A or 63A version to match the maximum load current for your installation. Configure voltage and time settings during commissioning to suit the protected equipment and local supply characteristics.
