Relay Automotive Procurement Notes

Verify that the specific suffix 'R' corresponds to the required resistor or component configuration as defined in the official CIT datasheet, as ordering suffixes may alter internal circuitry. Confirm that the 1.6W coil power rating matches the target application's thermal and electrical constraints. Ensure the sealed construction meets the environmental protection requirements for the intended installation location within the vehicle.

Relay Automotive Selection Notes

Select this model when a Single Pole Double Throw configuration is required for high-current automotive loads. The 12VDC coil voltage aligns with standard vehicle electrical systems. Consider the physical footprint and quick connect termination style for compatibility with existing harness designs. Verify that the 40A N.O. and 30A N.C. current ratings exceed the peak load requirements of the controlled equipment.
