LED Voltage and Overcurrent Relay Protector (AC80–400V, 1–63A) Key benefits Protects equipment from voltage and current faults by instantly cutting power when set limits are exceeded, reducing risk of damage and downtime. Realtime voltage and current readouts on a dual LED display enable fast diagnosis of supply problems and simplify maintenance. Fully adjustable protection and delay settings allow precise integration with different machines and electrical systems. What it does Provides adjustable overvoltage, undervoltage and overcurrent protection for AC80–400V systems rated 1–63A. Uses a relay output to disconnect power immediately on fault conditions, preventing overloads and unsafe operating states. Displays live voltage and current values on a dual LED screen for accurate monitoring. Key specifications Voltage compatibility: AC 80–400 V Current rating: adjustable 1–63 A (overcurrent setting) Overvoltage range: adjustable AC 230–300 V Undervoltage range: adjustable AC 140–200 V Boot delay (startup delay): adjustable 1–600 s Reset delay (reengage delay): adjustable 30–300 s Power consumption: < 2 W Mechanical life: > 100,000 operations Construction material: flameretardant plastics Adjustable settings for safe, flexible operation Overvoltage and undervoltage thresholds can be set to match the tolerance of connected equipment. Overcurrent threshold adjustable across 1–63 A to protect motors, transformers and distribution circuits. Configurable boot and reset delays prevent nuisance trips from transient events and allow staged restarts for sensitive equipment. Durability and safety Housings are molded from flameretardant plastics for improved fire safety. Designed and tested for long life with mechanical endurance exceeding 100,000 operations. Low standby power consumption (<2 W) reduces impact on overall system energy use. Typical applications Industrial motor protection: safeguard pumps, compressors and conveyor motors against sustained overcurrent and harmful voltage conditions. Commercial electrical panels: protect lighting circuits, HVAC units and service equipment in factories, warehouses and retail facilities. Control and automation systems: integrate into PLC cabinets or control panels to prevent damage from supply fluctuations and to provide clear fault indication. Why use this protector Clear, realtime LED monitoring combined with precise, useradjustable protection settings helps prevent equipment damage and reduces troubleshooting time. Broad voltage range (AC80–400V) and wide current adjustment (1–63A) make it compatible with many industrial and commercial installations. Rugged construction and long mechanical life provide reliable performance in demanding environments. Installation note Intended for AC systems within the specified voltage and current ranges; configure thresholds and delays according to the equipment manufacturer's recommendations and local electrical codes.
