A3M1CCQ24VDC2D

Relay Automotive Overview

The A3M1CCQ24VDC2D is an automotive relay manufactured by CIT Relay and Switch. It features a coil voltage of 24 VDC with a maximum rating of 31.2 VDC. The contact arrangement is SPDT (Single Pole Double Throw), designated as 1C. Standard contact ratings are 60A @ 14VDC for the Normally Open (N.O.) circuit and 40A @ 14VDC for the Normally Closed (N.C.) circuit. Heavy-duty ratings reach 80A @ 14VDC N.O. and 70A @ 14VDC N.C. The device supports a maximum switching voltage of 75VDC and power up to 1120W. Contact resistance is less than 30 milliohms initially, utilizing AgSnO2/In2O3 materials.
