A3K1ASQ24VDC1.6D

Relay Automotive Overview

The A3K1ASQ24VDC1.6D is a Maxi ISO sized automotive relay manufactured by CIT Relay and Switch, designed for high-current DC applications. It features a non-latching coil operating at 24VDC with a current draw of 66.7 mA. The contact configuration is SPST-NO (Form A), capable of switching up to 80A at 14VDC in heavy-duty mode, with a maximum switching voltage of 145VDC. The unit includes internal blowout magnets for arc suppression and is suitable for lamp control and DC motor applications.

Relay Automotive Feature Summary

• Maxi ISO sized form factor compatible with standard automotive sockets
• Internal blowout magnets provide enhanced arc suppression capabilities
• Sealed construction protects against environmental contaminants
• Capable of handling high switching voltages up to 145VDC

Relay Automotive Applications

• Automotive lamp control systems
• DC motor control circuits
• High-current automotive electrical distribution

Relay Automotive Procurement Notes

Verify the specific coil voltage rating of 24VDC matches the system design requirements before integration. Confirm that the SPST-NO contact form aligns with the intended circuit logic. Ensure the mounting environment supports the specified temperature range of -40°C to 125°C. Check for compatibility with standard Maxi ISO sockets if socketed installation is required.

Relay Automotive Selection Notes

Select this component when a high-current automotive relay is needed for 24VDC systems. The 80A heavy-duty rating makes it suitable for demanding loads compared to lower-rated alternatives. Consider the 145VDC maximum switching voltage if controlling inductive loads with high back-EMF. The sealed design is preferred for harsh automotive environments where moisture resistance is critical.

Relay Automotive Part Context

This part belongs to the A3K series of Maxi relays from CIT Relay and Switch. These are standardized automotive components widely used in vehicle electrical architectures. The series offers various contact arrangements and coil voltages to accommodate different chassis requirements while maintaining consistent physical dimensions for interchangeability within the Maxi form factor.

Relay Automotive Replacement Considerations

Compatible substitutes include other Maxi ISO sized relays with identical 24VDC coil ratings and SPST-NO contacts. Verify that replacement units support the same 80A current capacity and 145VDC voltage limit. Ensure the alternative part maintains the sealed construction and internal magnet specifications for equivalent performance.
