A11CSP48VDC1.2

Relay Automotive Overview

The A11CSP48VDC1.2 is a non-latching electromechanical relay manufactured by CIT Relay and Switch, designed for automotive applications. It features a 48VDC coil voltage with a coil current of 25 mA. The contact configuration is SPDT (1 Form C), rated for a maximum switching voltage of 75VDC and a current capacity of 30A. The device utilizes through-hole mounting with PC pins and operates within a temperature range of -40°C to 85°C.

Relay Automotive Feature Summary

• High current handling capability of 30A for robust load switching
• Automotive-grade construction ensuring stability in high-power motor control environments
• Non-latching operation provides reliable single-side return functionality

Relay Automotive Applications

• Automotive motor control systems
• High-power load switching circuits
• Industrial control cabinets requiring stable thermal behavior

Relay Automotive Procurement Notes

Verify the specific suffix 'D' if datasheet references indicate distinct packaging or terminal variations. Confirm that the 30A rating aligns with your circuit's peak load requirements. Ensure the 48VDC coil voltage matches your system's power supply. Check for any specific automotive qualification standards required by your application environment before finalizing procurement.

Relay Automotive Selection Notes

Select this component when a high-current SPDT switch is required for 48VDC automotive systems. The 30A rating distinguishes it from lower-capacity general-purpose relays. Consider the through-hole PC pin mounting style for board integration. Evaluate the 75VDC max switching voltage limit against your load's electrical characteristics to ensure safe operation within specified parameters.

Relay Automotive Part Context

This model belongs to the A11 series of automotive relays from CIT Relay and Switch. It shares design similarities with variants like A11CSQ48VDC1.2D but differs in mounting type and specific contact ratings. The series is characterized by robust construction suitable for demanding vehicular environments where reliability under vibration and thermal stress is critical.

Relay Automotive Replacement Considerations

Direct substitutes include the A11CSQ48VDC1.2D, which offers similar 48VDC coil and SPDT configuration but may differ in mounting style. Verify that replacement units maintain the 30A current rating and 75VDC switching limit. Ensure the alternative part number supports the same through-hole or compatible mounting method for your PCB layout.
