คุณลักษณะ :
- Can detect power source phase reversal before motor start also can detect Phase-loss and unbalance while motor operating or before motor start
- Suitable for main power source and motor starter circuit to prevent damage from insufficient phase or phase reversal
- Phase sequence detection-Output contact Release while phase reversal Phase-loss detection – 3sec fixed tripping delay
- 3-phase voltage balance decetion – 3sec fixed tripping delay
- 1sec fixed reset delay
- Install on DIN rail and no socket require
