A3F1ACQ24VDC2D

Relay Automotive Overview

The A3F1ACQ24VDC2D is an automotive relay from the A3M series manufactured by CIT Relay and Switch. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a high rated current of 80A at a maximum switching voltage of 75VDC. The coil operates on 24VDC with a resistance of 320 Ohms and consumes 1.8W of power. Designed for base mounting, it utilizes quick-connect terminals in various sizes. The unit includes a fully sealed diode and functions within a temperature range of -40°C to 125°C.

Relay Automotive Feature Summary

• High current switching capacity up to 80A for demanding automotive loads
• Fully sealed construction with integrated protection diode
• Robust terminal design compatible with multiple quick-connect sizes

Relay Automotive Applications

• Automotive electrical systems
• Heavy-duty vehicle lighting circuits
• Industrial control panels requiring high current isolation

Relay Automotive Procurement Notes

Verify the specific terminal size compatibility required for your harness connections before ordering. Confirm that the 24VDC coil voltage matches your system's power supply. Ensure the base mounting style aligns with your chassis or panel layout constraints. Check for any updated environmental compliance documentation if operating in restricted regions.

Relay Automotive Selection Notes

Select this component when a high-current single-channel switch is needed in space-constrained automotive applications. The 80A rating supports heavy loads like starter motors or large compressors. The sealed design protects against moisture and dust in harsh environments. Consider the 320 Ohm coil resistance for driver circuit current limitations.
