A3M1CCQ12VDC2

Relay Automotive Overview

The A3M1CCQ12VDC2 is a non-latching automotive relay manufactured by CIT Relay and Switch. It features an SPDT (1 Form C) contact arrangement with a heavy-duty switching capacity of up to 80A at 14VDC. The coil operates on 12VDC with a current draw of 150mA and resistance of 80 Ohms. Designed for chassis mounting, it utilizes quick-connect terminals and AgSnO2/In2O3 contact materials. The unit supports a maximum switching voltage of 75VDC and power of 1120W, with an initial contact resistance below 30 milliohms.

Relay Automotive Feature Summary

• High-capacity switching rated up to 80A for demanding automotive loads
• SPDT configuration providing both normally open and normally closed circuits
• Sealed construction suitable for harsh automotive environments
• RoHS compliant manufacturing with QS-9000 and ISO-9002 certification

Relay Automotive Applications

• Automotive lighting accessories control
• High-current accessory power distribution
• Chassis-mounted electrical circuit protection
• Lamp accessory switching systems

Relay Automotive Procurement Notes

Verify the specific suffix codes against official CIT documentation to confirm terminal style and coil specifications. Ensure the procurement order matches the required contact arrangement and voltage rating. Confirm RoHS compliance status if environmental regulations apply to the end application. Cross-reference the datasheet for exact dimensional tolerances before integration.

Relay Automotive Selection Notes

Select this model when an SPDT configuration is required for high-current automotive applications. The 80A rating supports heavy-duty loads such as auxiliary lighting or pumps. The 12VDC coil voltage aligns with standard vehicle electrical systems. Chassis mounting and quick-connect terminals facilitate straightforward installation in confined engine compartments.

Relay Automotive Part Context

This component belongs to the A3M series of electromechanical relays from CIT Relay and Switch. The series is characterized by large switching capacities and compact dimensions relative to their current ratings. These relays are engineered for automotive and lamp accessory markets, offering robust performance under vibration and temperature extremes typical of vehicle operations.

Relay Automotive Replacement Considerations

Direct substitutes include the A3M1CSQ12VDC2, which shares identical SPDT contact form, 80A rating, and 12VDC coil specifications. Verify that the replacement part maintains the same chassis mounting footprint and terminal interface type to ensure mechanical compatibility without modification.
