A3M1ACQ24VDC1D

Relay Automotive Overview

The A3M1ACQ24VDC1D is an automotive relay manufactured by CIT Relay and Switch, designed for high-current applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a rated switching current of 60A at a maximum voltage of 75V DC. The device utilizes a 24V DC coil with a resistance of 320 Ohms and operates within a temperature range of -40°C to 125°C. Constructed with silver tin oxide contacts, it offers robust performance in demanding automotive environments.

Relay Automotive Feature Summary

• High current capacity suitable for heavy automotive loads
• Integrated protection diode for coil suppression
• Sealed construction ensuring environmental durability
• Quick-connect terminals for simplified installation

Relay Automotive Applications

• Automotive lighting circuits
• Motor control systems
• Heater and fan regulation
• Auxiliary power distribution

Relay Automotive Procurement Notes

Verify the specific contact material composition and terminal dimensions against the official datasheet before integration. Confirm that the 24V DC coil voltage aligns with the target vehicle's electrical system architecture. Ensure the mounting base supports the required quick-connect pin sizes for secure mechanical attachment.

Relay Automotive Selection Notes

Select this component when a high-current SPST solution is required for 24V automotive networks. The sealed design provides necessary protection against moisture and dust compared to unsealed alternatives. Consider the thermal management requirements given the 125°C operating limit and the specific contact material properties for long-term reliability under load.
