Product overview A DIN rail mounted protective relay designed for single phase 230V systems with a rated current of 63A. Combines adjustable under voltage protection, dual over voltage protection, current display, and surge protection into one compact module for easy installation in electrical distribution panels. Key benefits Prevents damage from voltage abnormalities by providing both over voltage and adjustable under voltage protection. Built in current display allows quick visual checks of load current without separate metering equipment. 63A rating supports mid level circuits and loads without the need for additional relays. DIN rail form factor simplifies panel mounting and integration into standard distribution and control cabinets. Surge protective function adds an extra layer of defense against transient voltage spikes. Main features Rated current: 63A Rated voltage: 230V Functions: dual over voltage protection, adjustable under voltage protection, surge protection, real time current display Mounting: DIN rail compatible User controls: adjustable undervoltage set point for tailored protection to the application Why customers need this product Protects electrical equipment and connected loads from damaging voltage events. Eliminates the need for separate current meters and many discrete protection components, saving panel space and wiring complexity. Adjustable under voltage setting adapts protection to different equipment tolerances and operational requirements. Typical applications Distribution and control panels in light industrial and commercial facilities for general load protection. Motor control circuits and pump systems where voltage sags or surges can cause equipment stress or trips. Backup power systems, UPS infeed circuits, and generator interfaces where stable voltage and surge defense are important. Operation and installation notes Designed for DIN rail mounting in standard electrical cabinets. Intended for use on 230V single phase circuits with loads up to 63A. Set undervoltage threshold according to the acceptable operating range of connected equipment before commissioning. Use alongside appropriate overcurrent protection devices and follow local electrical codes for safe installation. What this product delivers A compact, easy to install protective relay that combines voltage protection, surge defense, and current monitoring in a single 63A 230V DIN rail module. It provides a practical solution for protecting circuits and simplifying panel design while allowing adjustable protection settings for application specific needs.
