SSU31/AC400V

- 1 changeover contact
- Contact material AgNi
- Pluggable
- Monitoring: phase sequence, phase failure, undervoltage

ELDAS®: 543730450

The SSU31 is used to monitor the phase sequence and detect undervoltage and phase failure in three-phase networks.
The monitoring function is used to ensure the drive direction of pumps and conveyor systems, particularly in mobile systems with plug connections. Switching off at a defined undervoltage and phase failure protects against malfunctions and damage due to overheating.
