Features:
1. When the circuit has over-voltage or under-voltage, over-current problems, the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides.
2. The 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 3 phase AC 380V, 50/60Hz, rated working current 40A / 50A / 63A / 80A or less loads.
4. Remark:
(1) Devices do not have overload and short circuit protection. Please use it with DZ47, C65 mini circuit breakers, etc.
(2) After pressing SET, if there is no operation within 10 seconds, devices status will be automatically exited, the changed parameters will not be saved.
(3) When ABC character is displayed on the LCD screen. Please arbitrarily reverse the two phase lines (fire line).
