- For protection of sensitive three phase loads, protection against phase unbalance, phase loss and phase reversal, overvoltage and undervoltage
- 3 x 600 to 720 VAC overvoltage/3 x 450 to 570 VAC undervoltage
- Monitoring of three phase mains for phase sequence (can be switched off), phase failure, over and undervoltage as well as phase unbalance
- ON delayed or OFF delayed tripping delay selectable
- TRMS measuring principle
- Housing material for highest fire protection classification UL 94 V-0
- Tool-free mounting on DIN rail as well as demounting
- 3 LEDs for indication of operational states
- Powered by the measuring circuit
- Automatic phase sequence correction configurable
- Threshold values for over and undervoltage as well as phase unbalance are adjustable as absolute values
- Precise adjustment by front-face operating controls
- Without neutral connection
- Tripping delay TV can be adjusted or switched off by means of a logarithmic scale (0 s, 0.1 to 30 s)
