Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct coil voltage and contact configuration. Confirm that the 48VDC rating aligns with the target system's operational parameters. Check for RoHS compliance status if required by project specifications. Ensure the selected variant matches the intended mounting style, whether PCB or quick connect, as physical interfaces may vary between sub-models within the same series.

Relay Automotive Selection Notes

Select this component when an application requires a high-current SPDT switch capable of handling 80A loads. The 48VDC coil rating makes it suitable for heavy-duty vehicle electrical systems. Consider the physical dimensions and mounting requirements to ensure fit within the designated enclosure. Evaluate the thermal performance and switching speed if the application involves frequent cycling or high ambient temperatures compared to lower-capacity relays.

Relay Automotive Part Context

This model belongs to the A3 series of automotive relays from CIT Relay and Switch, which are engineered for high DC load applications. The series is characterized by blowout magnets and large switching capacities, distinguishing it from lower-amperage counterparts like the A2 or A5 series. These relays are widely used in automotive and industrial sectors where reliability under high stress is critical.
