55. DC Motor Relay Selection

✅ Relay Type: General Purpose, matches the requirement.
✅ Mounting Type: Through Hole, matches the PCB relay requirement.
✅ Coil Voltage: 12VDC, exactly matches the required coil voltage.
✅ Contact Form: SPST-NO (1 Form A), acceptable because only normally open switching is needed.
✅ Contact Rating (Current): 20A, exceeds the minimum required ≥5A and is suitable for a 3A motor load.
✅ Switching Voltage: Rated up to 30VDC max, which is suitable for switching a 12VDC motor load.
✅ Coil Type: Non Latching, matches the requirement.
✅ Termination Style: PC Pin, matches the requirement.
✅ Operating Temperature: -40°C to 105°C, meets and exceeds the required -40°C to +85°C range.
✅ Approval Agency: CUR, TUV, UL; cURus-equivalent approval requirement is satisfied.

All required specifications are satisfied, so this relay is approved for the 12V DC motor switching application.
