Protect your entire electrical setup with a smart, precision-driven safeguard that reacts before problems escalate. This Digital Display Adjustable Over/Under Voltage and Current Protector is engineered for continuous 220V monitoring, giving you real-time visibility and total control over your connected equipment. Instead of relying on passive fuses, you can now define your own safety thresholds-set over-voltage protection anywhere from 230V to 300V, under-voltage cutoff from 140V to 210V, and current limits from 1A to 40A. Once a fault condition clears, the unit automatically restores power, eliminating the need for manual resets and reducing downtime.
Designed for professional and home use alike, this protector mounts effortlessly onto a standard 35mm DIN rail, making it a clean, space-saving addition to any distribution board, workshop, or appliance circuit. The bright digital display keeps you informed of live voltage and current readings at a glance, while the tactile push-button interface allows quick, tool-free adjustments. Whether you are safeguarding an HVAC system, a water pump, or a full server rack, this device acts as a reliable 40A circuit protector that bridges the gap between a basic breaker and a full monitoring relay.
Built to handle AC 220V/230V at 50/60Hz, this adjustable voltage relay delivers consistent performance in demanding environments. Its auto-reset functionality ensures your systems stay operational without constant supervision, making it an essential power supply monitor for anyone serious about equipment longevity.
