A3K1CSQ24VDC1.6D

Relay Automotive Overview

The A3K1CSQ24VDC1.6D is a non-latching electromechanical relay manufactured by CIT Relay and Switch. It features a SPDT (Single Pole Double Throw) contact configuration, also known as one Form C. The coil operates at 24VDC with a current draw of 66.7 mA. The contacts are rated for 80A at up to 145VDC. The unit includes a built-in diode for back-EMF suppression and utilizes magnetic blowout technology for arc protection.

Relay Automotive Feature Summary

• Sealed fully enclosed design for environmental protection
• Built-in diode for coil voltage spike suppression
• Magnetic blowout mechanism for enhanced arc control

Relay Automotive Applications

• High-current DC switching applications
• Industrial control systems requiring robust contact ratings
• Automotive or heavy machinery electrical circuits

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct coil voltage and contact form. Confirm that the sealed enclosure rating meets the operational environment requirements. Check for RoHS compliance status if required by project specifications. Ensure the 80A contact rating aligns with the maximum load current of the intended circuit application.

Relay Automotive Selection Notes

Select this component when high DC current capacity is required in a compact sealed package. The SPDT configuration allows for switching between two separate circuits. The 24VDC coil voltage must match the available control signal. Consider the magnetic blowout feature for applications involving significant inductive loads where arc suppression is critical for contact longevity.

Relay Automotive Part Context

This part belongs to the CIT Maxi relay series, designed for general-purpose use with high current capabilities. CIT Relay and Switch produces RoHS compliant electromechanical relays. The series typically offers wide coil voltage ranges and various contact arrangements. This specific model represents a high-amperage variant within their standard product line.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT models with identical 24VDC coil and 80A SPDT ratings. Verify mechanical footprint and pinout compatibility before substitution. Ensure equivalent sealing standards and arc suppression mechanisms are present in any alternative component.
