A3M1ACQ12VDC1

Relay Automotive Overview

The A3M1ACQ12VDC1 is an automotive electromechanical relay manufactured by CIT Relay and Switch. It features a single-pole single-throw normally open (SPST-NO) contact configuration, designated as 1A. The coil operates at a rated voltage of 12 VDC with a maximum switching current capacity of 60 A at 14 VDC. The component supports quick connect termination and chassis mounting, designed for high-current applications in automotive and lamp accessory systems.

Relay Automotive Feature Summary

• SPST-NO contact arrangement for standard switching control
• High current handling capability up to 60 A
• Quick connect terminal interface for rapid installation
• Chassis mount design for secure physical attachment

Relay Automotive Applications

• Automotive electrical circuit protection and control
• Lamp accessory power distribution
• Heavy-duty load switching in vehicle systems

Relay Automotive Procurement Notes

Verify the exact part number against official CIT Relay and Switch documentation to ensure compatibility with 12 VDC coil requirements and 60 A contact ratings. Confirm that the SPST-NO configuration matches the intended circuit logic. Ensure the quick connect terminals align with existing harness connectors. Check for RoHS compliance status if required by specific manufacturing standards.

Relay Automotive Selection Notes

Select this component when a robust SPST-NO relay is needed for automotive loads requiring up to 60 A. The 12 VDC coil voltage must match the system supply. Consider the chassis mount form factor and quick connect termination style for integration into existing assemblies. Verify that the 75 VDC maximum switching voltage rating exceeds the application's peak voltage requirements.

Relay Automotive Part Context

This relay belongs to the CIT A3 series, which is characterized by large switching capacities suitable for demanding automotive environments. The series includes variants with different contact arrangements and coil voltages. The A3M1ACQ12VDC1 specifically utilizes the 1A contact configuration, distinguishing it from SPDT or NC options within the same product family.

Relay Automotive Replacement Considerations

Direct substitutes include other CIT A3 series relays with identical 12 VDC coils and 60 A SPST-NO contacts, such as A3M1ASQ12VDC2D, provided the mechanical mounting and terminal types are compatible. Cross-manufacturer replacements require matching coil resistance, contact rating, and physical dimensions.
