A3KM1ASQ48VDC1.6

Relay Automotive Overview

The A3KM1ASQ48VDC1.6 is a sealed automotive relay manufactured by CIT Relay and Switch, designed for chassis mounting applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration with an 80A rated switching current at 48VDC. The coil operates on a 48VDC supply with a power consumption of 1.6W. The unit utilizes quick connect termination styles available in multiple sizes and incorporates a built-in suppression diode. It functions within an operating temperature range of -40°C to 125°C.

Relay Automotive Feature Summary

• Sealed construction suitable for demanding automotive environments
• High current capacity of 80A for heavy load switching
• Integrated suppression diode for coil protection
• Versatile quick connect termination options

Relay Automotive Applications

• Automotive electrical systems
• Heavy duty vehicle accessories
• Industrial control circuits requiring high current switching

Relay Automotive Procurement Notes

Verify the specific suffix variant required, as designations such as 'R' or 'D' may indicate differences in internal components or packaging configurations. Confirm that the 48VDC coil voltage aligns with the target system's power supply standards. Ensure the chassis mount footprint and quick connect pin dimensions match the existing assembly requirements before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a robust, sealed relay capable of handling 80A loads is necessary for 48VDC automotive or industrial applications. The SPST-NO configuration provides simple on/off control for high-power devices. Consider the integrated diode feature for simplified circuit design without external snubbers. Evaluate the physical dimensions and mounting style to ensure compatibility with the intended chassis space.

Relay Automotive Part Context

This part belongs to the CIT automotive relay series, characterized by high durability and sealing against environmental factors. The A3KM series specifically targets high-current applications, distinguishing itself from lower-capacity general-purpose relays. The 48VDC coil specification caters to commercial vehicles and specialized machinery rather than standard passenger cars.

Relay Automotive Replacement Considerations

Cross-reference with other CIT models offering identical 80A ratings and 48VDC coils. Verify mechanical footprint compatibility if substituting with non-CIT brands. Ensure the replacement maintains the sealed construction and diode inclusion to preserve circuit integrity.
