| Series Description: Current monitoring relay of Imax level in 1P - AC |
- It serves for monitoring of heating in rail-switches, heating cables, consumption of 1-phase motors, indicates current fl ow.
- Flexible adjustment by potentiometer.
- Adjustable delay 0.5 - 10 s to eliminate short current peaks.
- It is possible to use for current scanning from current transformer.
- Supply is galvanically separated from measured current, it must be in the same phase.
