A3M1ACQ12VDC2R

Relay Automotive Overview

The A3M1ACQ12VDC2R is an automotive relay manufactured by CIT Relay and Switch, designed for chassis mounting with quick connect terminals. It features a single-pole single-throw normally open (SPST-NO) contact configuration capable of handling up to 80A at 75VDC. The coil operates on 12VDC with a current draw of 75mA and resistance of 160 Ohms. It includes a built-in suppression diode and is fully sealed. The unit supports a wide operating temperature range from -40°C to 125°C and complies with RoHS3 standards.

Relay Automotive Feature Summary

• High switching capacity rated at 80A for demanding automotive loads
• Integrated suppression diode for coil protection
• Fully sealed construction for environmental durability
• Chassis mount design with quick connect termination

Relay Automotive Applications

• Automotive lighting circuits
• Motor control systems
• Heater and fan controls
• General automotive power distribution

Relay Automotive Procurement Notes

Verify the specific terminal size compatibility for the quick connect pins against the target harness connector specifications. Confirm that the chassis mounting hole dimensions align with the available panel or bracket space. Ensure the application voltage does not exceed the 75VDC maximum rating for the contacts. Check that the 12VDC coil supply matches the vehicle's electrical system requirements.

Relay Automotive Selection Notes

Select this component when a high-current single-channel switch is required in automotive environments. The 80A rating distinguishes it from lower-capacity signal relays. The integrated diode simplifies circuit design by eliminating external flyback components. Consider the chassis mount style if PCB space is limited but panel access is available.
