Feature: 1. SAFE MATERIAL: Using PC flame retardant material, possess overvoltage protection, undervoltage protection and voltage display(voltage measurement), safer and more reliable to use 2. REGULATION: Providing safe protection for electrical appliances, manually adjust over voltage, under voltage, over current protection values 3. PREVENT DAMAGE: Can prevent the frequent on and off of unstable voltage from causing additional damage to electrical appliances, so as to achieve secondary protection 4. MULTIPLE FUNCTIONS: The current protector has the functions of reset mode selection, fault inquiry, and factory reset 5. CLEAR DISPLAY: Over under voltage protector come with double display, make the data clear at a glance, support din rail installation Specification: Item Type: Over Under Voltage Protector Material: PC flame retardant Current: 63A Overvoltage Protection (uvo): 240V to 300V Undervoltage Protection (uve): 140V to 210V Shutdown Delay Time: 2s (can be set 1-300s) Self Reset Protection Delay: 30s (1-300s) Rated Frequency: 50/60Hz Error: 2% Output Contact: 1NO Electrical Life: 100000 Times Mechanical Life: 1 Million times Protection Level: IP20 Height: 2000meter or less Operating Temperature: -50℃-55℃ Humidity: ≤50% at 40℃ (no condensation) Humidity Temperature: -30℃ to 70℃ Package List: 1 x Over Under Voltage Protector
