The GIC CMU110 is a compact DIN rail-mounted overcurrent monitoring relay with an integrated current transformer for monitoring AC loads. It provides an adjustable trip threshold, selectable relay fail-safe behaviour and overload indication.
Key features
- Integrated current transformer (no external CT required)
- Adjustable 2-20A AC overcurrent threshold
- True RMS current measurement
- Selectable fail-safe or non-fail-safe relay operation
- 15% fixed threshold hysteresis
- Green power and red overload LEDs
- 17.5mm DIN rail housing
