Single-phase protection relay

over-voltageunder-voltageAC

The self-reset over voltage and under voltage protective device considered modular design. The circuit board adopted good quality Latching relays and others components with reliable performance. When the power supply is unstable (voltage is too high or too low), the protection function will be activated automatically. Once the voltage exceeds the limited range, it will be cut off automatically, so that to protect the peoples and electrical appliances /equipment in safe, also the protective device will be reset by itself in 60 seconds, when the power returns to normal. Technical index Rated AC voltage : 230±10% VAC, Frequency 50-60HZ Reset voltage value after normal voltage : 240-260VAC Reset voltage value after normal voltage:190 ±5VAC Electricity reset time after normal voltage: ＜60S Power consumption：<1W Electrical life: 100,000 Cycles Mounting : DIN RAIL TH35mm Dimension: L=77.5mm W37mm H66mm
