A3M1UCQ12VDC1R

Relay Automotive Overview

The A3M1UCQ12VDC1R is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a single-pole single-throw normally open (SPST-NO) contact arrangement with a rated current of 60A at 14VDC. The coil operates on 12VDC with a resistance of 80 Ohms and consumes 1.8W of power. Constructed with AgSnO/In2O3 contact materials, it supports a maximum switching voltage of 75VDC. The unit utilizes quick connect terminals for mounting and is sealed for environmental protection.

Relay Automotive Feature Summary

• High switching capacity up to 80A in heavy-duty configurations
• Sealed construction suitable for harsh automotive environments
• Quick connect terminal style for efficient PCB or harness installation

Relay Automotive Applications

• Automotive lighting circuits
• Lamp accessories control
• General automotive electrical load switching

Relay Automotive Procurement Notes

Verify the specific contact material variant, as CIT offers both AgSnO and In2O3 options within this series. Confirm that the 12VDC coil voltage matches the system supply. Ensure the quick connect terminal dimensions align with the target connector interface. Check RoHS compliance status if required by the end product specifications.

Relay Automotive Selection Notes

Select this component when a compact, high-current automotive relay is required for 12V systems. The SPST-NO configuration is ideal for simple on/off load control. Consider the thermal management requirements given the 60A rating. Compare against the A3M1ASQ series if higher current ratings are needed.
