A3F1CSQ12VDC2R

Relay Automotive Overview

The A3F1CSQ12VDC2R is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a SPDT (Single Pole Double Throw) contact arrangement, commonly referred to as Form C, which allows for versatile circuit control including changeover functions. The device operates with a 12VDC coil voltage and utilizes quick connect terminals for efficient PCB or panel mounting. Certified under QS-9000 and ISO-9002 standards, it supports heavy-duty loads up to 80A at 14VDC, making it suitable for demanding automotive and industrial environments.

Relay Automotive Feature Summary

• SPDT contact configuration providing changeover switching capability
• High current capacity supporting heavy-duty automotive loads
• Quick connect terminal design for simplified installation
• Compliant with QS-9000 and ISO-9002 manufacturing certifications

Relay Automotive Applications

• Automotive lighting systems
• Industrial control circuits
• Heavy-duty accessory power management

Relay Automotive Procurement Notes

Verify the specific contact arrangement and coil voltage requirements against system schematics before procurement. Confirm that the quick connect terminal style matches existing harness connectors. Ensure environmental ratings meet operational temperature ranges. Cross-reference part numbers with official CIT Relay and Switch documentation to avoid substitution errors.

Relay Automotive Selection Notes

Select this model when a changeover function is required rather than simple on/off switching. Consider the 80A heavy-duty rating for high-load applications compared to standard 60A variants. Evaluate the physical dimensions and mounting style against available board space. Verify compatibility with 12VDC control signals and check if diode protection is needed for inductive loads.
