Description
- Used, for example, for monitoring heating rods in railway switches, heating cables, current flow indication, monitoring the load of single-phase motors, etc.
- Stepless trip current setting via potentiometer.
- Adjustable delay 0.5 – 10 s (to eliminate short-term spikes).
- Can also be used for current sensing via a current transformer.
- The power supply is galvanically isolated from the measured current.
