A3M1CSQ24VDC2R

Relay Automotive Overview

The A3M1CSQ24VDC2R is a heavy-duty automotive relay manufactured by CIT Relay and Switch. It features a single-pole double-throw (SPDT) contact configuration, providing one normally open and one normally closed circuit path. The unit operates on a 24VDC coil voltage with a maximum switching voltage of 75VDC. It supports high current loads, rated at 80A for the normally open contact and 30A for the normally closed contact at 14VDC. The device includes an integrated bracket for secure mounting in vehicle applications.

Relay Automotive Feature Summary

• Heavy-duty construction designed for demanding automotive environments
• Integrated mounting bracket ensures stable installation
• Dual contact paths allow simultaneous control of separate circuits

Relay Automotive Applications

• Automotive lighting systems
• High-current accessory control
• Vehicle electrical distribution

Relay Automotive Procurement Notes

Verify the specific ordering suffix to confirm the inclusion of the diode or resistor component, as this affects the internal protection circuitry. Ensure the required coil voltage matches the 24VDC specification. Confirm that the SPDT contact arrangement aligns with the intended circuit design requirements before finalizing the purchase order.

Relay Automotive Selection Notes

Select this model when a robust SPDT relay is required for 24VDC automotive systems. The 80A rating suits high-load applications such as heavy lighting or auxiliary power devices. Verify that the physical dimensions and bracket style fit the available space within the vehicle's fuse box or relay panel assembly.
