Over voltage protective device adjustable DIN rail holder with automatic recovery 230V 63A 1. Wide range of applications: the voltage limiter is stable and reliable to achieve automation function, used in mass production of household appliances 2. Fireproof PC: over voltage protective device shell adopt reinforced PC material, flame retardant and high temperature resistant, more safe to use 3. Auto recovery function: above voltage limiter support automatic recovery, without instructions, when the voltage is too high or too low, the load side power automatically detects the line voltage, and automatically closes to restore the power supply once the line voltage is recovered online 4. Safety protection: over and under voltage limiter to ensure safe operation of household appliances, when the voltage is too high or too low, automatically cut off the power on the load side, prevent burning electrical, ensure the safety of electricity 5. Excellent performance: adjustable under voltage limiter is made with excellent workmanship, has compact appearance and stable performance, can ensure durability and stability Specification: Item type: voltage protective device Material: PC Rated voltage: 230VAC Current : 63A Overvoltage protection range: 230V to 300V Undervoltage protection range: 140V to 210V Rated frequency: 50/60Hz U and error: 2% Voltage measurement accuracy: 1% Rated insulation voltage: 400V output: 1NO Electric life: 100000 times Mechanical times 1000000 Life Protection Level: IP20 Height: meter 2000 Operating Temperature: -50-55 Humidity: 50% at 40 (non-condensing) Humidity Temperature: -30 to 70 How to use: Install and use directly.
