A3F1ACQ24VDC1

Relay Automotive Overview

The A3F1ACQ24VDC1 is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a coil voltage of 24 VDC with a coil current of 75 mA and operates at a maximum switching voltage of 75 VDC. The contact configuration is SPST-NO (1 Form A), providing a standard contact rating of 60 A and a heavy-duty rating of 80 A at 14 VDC. The component utilizes AgSnO2 In2O3 contact material with initial contact resistance below 30 milliohms and supports a maximum switching power of 1120 W.

Relay Automotive Feature Summary

• SPST-NO contact arrangement for single-pole single-throw normally open operation
• High current capacity supporting up to 80A in heavy-duty configurations
• Sealed construction suitable for automotive environments with dust cover options
• Quick connect terminal mounting for simplified PCB or harness integration

Relay Automotive Applications

• Automotive lighting systems
• Lamp accessories
• General automotive electrical circuits
• Heavy-duty load switching

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure correct terminal type and sealing status. Confirm that the 24 VDC coil specification matches the target system voltage. Check for RoHS compliance documentation if required by project specifications. Ensure the selected variant aligns with the intended current load requirements between standard and heavy-duty ratings.

Relay Automotive Selection Notes

Select this model when a 24 VDC control signal is available and a normally open contact path is required. The SPST-NO form factor simplifies circuit design compared to SPDT alternatives. Consider the 80A heavy-duty rating if the application involves high-inrush loads typical in automotive lighting. Verify physical dimensions and quick-connect terminal compatibility with existing harnesses before finalizing the design.
