A3F1ASQ24VDC2D

Relay Automotive Overview

The A3F1ASQ24VDC2D is an automotive SPST-NO relay from CIT Relay and Switch, rated for 80A at 75VDC. It features a 24VDC coil with 1.8W power consumption and 75mA current draw. The unit utilizes AgSnO2/In2O3 contact materials with less than 30 milliohms initial resistance. Dimensions are 28.5 x 28.5 x 26.5 mm (40.0 mm). It operates between -40°C and 125°C, with a 7 ms make time and 5 ms break time.

Relay Automotive Feature Summary

• High switching capacity up to 80A for heavy-duty automotive applications
• Sealed construction with integrated protection diode
• Compatible with chassis mounting via quick connect terminals

Relay Automotive Applications

• Automotive lighting systems
• Lamp accessories control
• Heavy load circuit switching in vehicles

Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required coil voltage and terminal configuration. Confirm that the sealed design and diode inclusion align with system requirements. Ensure the chassis mount style fits the intended assembly space. Cross-reference the contact arrangement to confirm SPST-NO functionality before procurement.

Relay Automotive Selection Notes

Select this component when high current handling up to 80A is required for automotive loads. The 24VDC coil specification suits standard vehicle electrical architectures. Consider the physical dimensions and quick-connect terminals for integration. Verify thermal performance within the -40°C to 125°C operating range for harsh environments.

Relay Automotive Part Context

This part belongs to the CIT A3 series of automotive relays, designed for robust performance in vehicle environments. The series offers various contact arrangements and coil voltages. The A3F1ASQ24VDC2D specifically provides a single pole single throw normally open configuration with high current capability.

Relay Automotive Replacement Considerations

Direct substitutes include other CIT A3 series relays with identical 24VDC coils and SPST-NO contacts, such as A3M1ASQ24VDC2D, provided terminal styles and mounting configurations are compatible.
