A11CSP48VDC1.2D

Relay Automotive Overview

The A11CSP48VDC1.2D is an automotive relay manufactured by CIT Relay and Switch, designed for through-hole mounting with a sealed construction. It features a single-pole double-throw (SPDT) contact configuration, providing one Form C circuit. The coil operates at a rated voltage of 48VDC with a power consumption of 1.2W. The contacts are rated for a maximum switching current of 30A and a maximum switching voltage of 75VDC. This component utilizes quick connect terminals for installation and is certified to Micro 280 and ISO standards, ensuring reliability in demanding automotive environments.

Relay Automotive Feature Summary

• Sealed design suitable for harsh automotive environments
• High switching capacity up to 30A for heavy loads
• Quick connect mounting for simplified assembly
• Compliance with Micro 280 and ISO certification standards

Relay Automotive Applications

• Automotive electrical systems
• Lawn care and maintenance equipment
• Marine applications
• Agriculture machinery

Relay Automotive Procurement Notes

Verify the specific ordering suffix 'D' against the manufacturer's official documentation to confirm the inclusion of the internal flyback diode (1N4005). Ensure the procurement request specifies the quick-connect terminal style rather than PC pin variants. Confirm that the 48VDC coil rating matches the target system voltage to prevent operational failure or excessive heat generation during continuous duty cycles.

Relay Automotive Selection Notes

Select this model when a high-current SPDT switch is required for 48V automotive circuits. The sealed housing protects against moisture and dust, making it suitable for under-hood or external vehicle mounting. Compare coil resistance and pull-in voltage specifications against the control source capabilities. Consider the physical dimensions and quick-connect orientation to ensure compatibility with existing harness layouts and connector types.

Relay Automotive Part Context

This component belongs to the A11 series of automotive relays from CIT Relay and Switch. The series is characterized by robust sealing and high current handling capabilities. It is distinct from general-purpose PCB relays due to its through-hole quick-connect interface and compliance with automotive-specific quality standards like Micro 280.

Relay Automotive Replacement Considerations

Direct substitutes must match the 48VDC coil voltage, 30A SPDT contact rating, and sealed quick-connect form factor. Verify equivalent certifications such as Micro 280 or ISO standards. Cross-reference pinout configurations and terminal styles to ensure mechanical interchangeability without rewiring.
