Features:
1. Common and difference protection mode, excellent performance.
2. The pluggable module allows a fast replacement in case of fail.
3. The grounding is realized through an earthing-clip on the DIN-rail and / or earthing - clamp.
4. No limiting in operating current due to parallel connecting method.
5. Mounting on 35mm rail, small space.
6. Rated voltage: Model with 5v, 12v, 15v, 24v, 30v, 48v, 60v available.
