A3K1ASQ48VDC1.6R

Relay Automotive Overview

The A3K1ASQ48VDC1.6R is an automotive relay from CIT Relay and Switch, featuring a single-pole single-throw normally open (SPST-NO) contact configuration. It operates with a 48VDC coil voltage and supports a maximum switching current of 80A at up to 145VDC. The unit utilizes quick-connect terminals for mounting and includes an integrated resistor in its design. Rated for operation between -40°C and 125°C, it employs silver tin oxide contacts to ensure durability in high-current automotive applications.

Relay Automotive Feature Summary

• High current capacity of 80A for demanding automotive loads
• Integrated resistor within the coil circuit design
• Sealed construction suitable for harsh environments
• Quick-connect terminal interface for rapid installation

Relay Automotive Applications

• Automotive lighting circuits
• Heavy-duty accessory power distribution
• Industrial control systems requiring 48VDC actuation

Relay Automotive Procurement Notes

Verify the specific suffix 'R' indicates the integrated resistor variant when sourcing replacements. Confirm that the 80A rating aligns with the load requirements of the target application. Ensure the 48VDC coil voltage matches the system supply to prevent under-driving or damage. Check compatibility with standard socket bases for quick-connect terminals.

Relay Automotive Selection Notes

Select this model for applications requiring high current switching capability driven by a 48VDC control signal. The SPST-NO configuration is suitable for simple on/off control of heavy loads. Consider the sealed design for protection against moisture and dust in engine compartments or external industrial enclosures where environmental sealing is critical.

Relay Automotive Part Context

This component belongs to the Maxi Relay series by CIT Relay and Switch, designed for robust automotive and industrial use. It offers higher current handling than standard Mini ISO relays. The series provides various contact forms and coil voltages to accommodate diverse electrical architectures in modern vehicles and machinery.

Relay Automotive Replacement Considerations

Direct substitutes include the A3KM1ASQ48VDC1.6R, which shares similar specifications. Verify pinout compatibility and physical dimensions before swapping. Ensure any replacement maintains the 80A rating and 48VDC coil requirement.
