A11CSQ48VDC1.2

Relay Automotive Overview

The A11CSQ48VDC1.2 is an automotive relay manufactured by CIT Relay and Switch, designed for high-power applications. It features a SPDT (1 Form C) contact configuration with a 30 A current rating. The coil operates at 48 VDC with a non-latching mechanism and consumes 1.2 W of power. The unit includes an integrated diode (1N4005) for surge suppression. It supports plug-in quick connect termination styles in multiple sizes and is sealed for environmental protection. Operating temperature ranges from -40°C to 85°C.

Relay Automotive Feature Summary

• SPDT contact form providing single pole double throw switching capability
• Integrated 1N4005 diode for coil voltage spike suppression
• Sealed construction suitable for harsh automotive environments
• Compatible with socketable mounting using quick connect terminals

Relay Automotive Applications

• High-power motor control systems
• Automotive electrical circuits requiring 48V DC operation
• Industrial equipment with sealed relay requirements

Relay Automotive Procurement Notes

Verify the specific suffix variant when ordering, as CIT Relay and Switch offers distinct versions such as A11CSQ48VDC1.2D and A11CSQ48VDC1.2R. Confirm that the required termination style matches the available quick connect options. Ensure the application environment falls within the specified -40°C to 85°C operating range. Check for RoHS compliance status if required by project specifications. Validate the 30 A rating against peak load currents.

Relay Automotive Selection Notes

Select this component for applications requiring a 48 VDC coil voltage and a 30 A switching capacity. The SPDT configuration allows for complex circuit control compared to SPST variants. Consider the sealed design for durability in outdoor or industrial settings. The integrated diode simplifies circuit design by eliminating the need for external flyback protection. Ensure physical space accommodates the plug-in form factor.

Relay Automotive Part Context

This part belongs to the A1 series of automotive relays from CIT Relay and Switch. The series includes various coil voltages and contact configurations, such as SPST and SPDT options. The A11CSQ48VDC1.2 specifically targets 48 VDC systems, distinguishing it from standard 12 V or 24 V automotive relays. It shares mechanical similarities with other socketable relays in the lineup but differs in electrical ratings.

Relay Automotive Replacement Considerations

Direct substitutes include A11CSQ48VDC1.2D and A11CSQ48VDC1.2R, which share identical core specifications. Verify terminal compatibility when swapping between these suffixes. Other CIT A-series relays may fit mechanically but require electrical verification.
