Sell ™Industrial Three Phase AC 380V Adjustable Surge Voltage Protectors Automatic Recovery Over Under Vo best price

Features: 1. When the circuit has over-voltage or under-voltage problems, the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides. 2. Protectors can automatically turn on the power supply when the circuit voltage returns to the normal. 3. STVP series SINOTIMER brand automatic over-voltage and under-voltage protectors are suitable for three-phase AC 380V, 50/60Hz. 4. These over-voltage and under-voltage protection devices have LCD screen, which makes the city very clear.
