More informationSingle-phase / three-phase permanent overvoltage protector
- Single-phase rated voltage (Ue): AC 230 V
- Single-phase permanent overvoltage protector: class Type II
- Three-phase rated voltage (Ue): AC 400 V
- Rated insulation voltage (Ui): 500 V
- Overvoltage tripping range: 280V ± 5%
- Undervoltage tripping range: 170V ± 5%
- Electromechanical resistance: ≥4000
- Mounted on the right side of the switch, trigger the combined device to trip in the event of undervoltage or overvoltage, effectively prevent the device from shutting down operation under abnormal supply voltage condition
