A3M1CCQ24VDC1R

Relay Automotive Overview

The A3M1CCQ24VDC1R is a CIT Relay & Switch electromechanical relay featuring a Mini ISO form factor. It operates on a 24 VDC coil with a resistance of 1.9 Ohms and supports a maximum switching voltage of 75 VDC. The SPDT contact arrangement provides a standard rating of 20A normally open and 15A normally closed at 14 VDC, with heavy-duty capacity up to 30A NO/20A NC. Constructed with AgSnO2 contacts, it ensures low initial contact resistance below 30 milliohms and handles up to 630W switching power. The unit measures approximately 26.0 x 26.0 x 24.5 mm, complies with RoHS standards, and utilizes PCB pin or quick connect mounting for automotive and lamp accessory applications.

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact coil resistance, contact material, and mechanical mounting variations. Ensure compatibility with existing PCB layouts or bracket mounts. Confirm that the 24 VDC coil voltage aligns with the system power supply. Check for any recent updates to QS-9000 or ISO-9002 certification status in the latest datasheet revision before finalizing procurement orders.

Relay Automotive Selection Notes

Select this model when a Mini ISO footprint is required alongside high current switching capabilities. The SPDT arrangement allows for single-pole double-throw functionality within a compact envelope. Consider the 24 VDC coil specification for systems operating at this voltage level. Evaluate the heavy-duty contact ratings if the application involves inductive loads or frequent switching cycles exceeding standard operational limits.

Relay Automotive Part Context

This component belongs to the CIT Relay & Switch Mini ISO series, which focuses on compact, high-current electromechanical relays for automotive and industrial markets. The series emphasizes reliability through certified manufacturing processes and standardized dimensions. It complements other CIT products by providing robust switching solutions in space-constrained environments where traditional relay sizes are prohibitive.

Relay Automotive Replacement Considerations
