Type 70.42, Line voltage monitoring relay for three-phase networks. Multi-function model, for monitoring three-phase networks (380 … 415 V, with neutral). Monitoring modes: undervoltage, overvoltage, window (overvoltage + undervoltage), phase rotation, phase loss, neutral loss (selectable), voltage asymmetry. Selectable Fault Memory
Features include:
- Detects phase failure error even in the presence of regenerated voltages
- Positive safety logic (make output contact opens when the measured value is out of limits)
- All functions and values can be easily set using the selectors and front regulators
- “Blade + cross” – both flat blade and cross head screwdrivers can be used to select the function, adjust the trimmer and release the rail clip
- Clear and immediate identification of the status through colored LEDs
- 2 changeover contacts 8 A
- Modular, 35 mm wide
- 35 mm rail (EN 60715) mounting
- Cadmium-free contacts
