Datasheet

DG55M
electric vehicle relay
• General purpose automotive or electric vehicle relays
• Up to 20A @ 80VDC switch capability (100K ops.)
• 40A continuous DC current capacity (at 23°C)
• Fits standard Mini-ISO relay sockets
• Special terminal arrangement - “ordinary” Mini-ISO relay inserted in DG55M socket will be safe.
• RoHS Compliant
