A3M1UCQ12VDC1D

Relay Automotive Overview

The A3M1UCQ12VDC1D is an automotive relay manufactured by CIT Relay and Switch, designed for high-current 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. The unit utilizes a metal bracket mounting style and includes quick-connect terminals for secure installation. It is fully sealed to protect against environmental factors.

Relay Automotive Feature Summary

• High switching capacity suitable for demanding automotive loads
• Fully sealed construction for environmental protection
• Metal bracket design for robust mechanical stability

Relay Automotive Applications

• Automotive lighting circuits
• Lamp accessories control
• General automotive electrical systems

Relay Automotive Procurement Notes

Verify the specific contact rating configuration, as datasheets may list variations such as 60A or 80A depending on the exact sub-model variant. Confirm that the 12VDC coil voltage matches the system supply. Ensure the quick-connect terminal dimensions align with existing harness connectors. Check for RoHS compliance requirements if applicable to the final assembly standards.

Relay Automotive Selection Notes

Select this component when a sealed automotive relay with a metal bracket is required for 12VDC systems. The SPST-NO configuration is standard for simple load switching. Consider the 60A rating for heavy-duty applications. Verify the operating temperature range meets the installation environment constraints. Compare against other A3 series variants for different coil voltages or contact arrangements.

Relay Automotive Part Context

This part belongs to the A3 series of automotive relays from CIT Relay and Switch. The series is certified under QS-9000 and ISO-9002 manufacturing standards. These relays are engineered for reliability in vehicle environments, offering large switching capacities and multiple mounting options including PCB pins and quick connects.

Relay Automotive Replacement Considerations

Compatible substitutes include the A3M1ASQ24VDC2D for 24VDC applications and the A3M1BCP12VDC1DR for PCB pin mounting. Ensure the replacement maintains the same SPST-NO contact form and adequate current rating for the specific load.
