A3K1ACQ12VDC1.6D

Relay Automotive Overview

The A3K1ACQ12VDC1.6D 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 capable of switching up to 150A at 12V. The unit operates with a 12VDC coil and includes an integrated protection diode. Constructed as a Maxi-style relay, it utilizes quick-connect terminals for mounting and is rated for a maximum switching voltage of 145VDC.

Relay Automotive Feature Summary

• High current capacity supporting up to 150A switching loads
• Integrated protection diode for coil circuit management
• Maxi form factor design for robust automotive environments

Relay Automotive Applications
