A2F1ACQ24VDC1.9R

Relay Automotive Overview

The A2F1ACQ24VDC1.9R is a general-purpose power relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features an SPST-NO (Form A) contact configuration with a maximum rated current of 40A. The coil operates at 24VDC with a current draw of 79.2mA and utilizes a non-latching mechanism. This sealed relay supports both PCB pin and quick connect mounting options, ensuring versatility in installation. It is certified by cURus and TUV agencies, indicating compliance with international safety standards for electrical components.

Relay Automotive Feature Summary

• High switching capacity up to 40A for robust load handling
• Sealed construction provides protection against environmental factors
• Flexible mounting options including PCB pins and quick connects

Relay Automotive Applications

• Automotive electrical systems
• Industrial control panels
• Power distribution units

Relay Automotive Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting styles and certification marks. Confirm that the 24VDC coil voltage aligns with the control circuit design. Check for RoHS compliance requirements if applicable to the end product. Ensure the 40A contact rating exceeds the maximum expected load current to prevent premature failure. Validate that the SPST-NO configuration meets the logical requirements of the switching application.

Relay Automotive Selection Notes

Select this model when a high-current single-pole switch is required in a compact form factor. The 40A rating makes it suitable for heavy loads compared to standard signal relays. Consider the available mounting methods; PCB pins are ideal for direct board integration, while quick connects offer flexibility for harness-based installations. The non-latching nature ensures the relay returns to its default state upon power loss, which is critical for safety in many industrial and automotive scenarios.

Relay Automotive Part Context

This component belongs to the CIT Relay and Switch power relay family, characterized by large switching capacities and small physical dimensions. The J115 and A2F series share similar design philosophies focusing on durability and high current handling. The A2F1ACQ variant specifically denotes the SPST-NO contact form and 24VDC coil specification within this lineup, distinguishing it from SPDT or different voltage variants.

Relay Automotive Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official CIT Relay and Switch catalogs for cross-reference data. Verify that any replacement maintains the same 40A contact rating, 24VDC coil voltage, and SPST-NO configuration to ensure functional equivalence.
