A11ASQ12VDC1.5

Relay Automotive Overview

The A11ASQ12VDC1.5 is a sealed automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration rated for 30 amperes at 14 VDC. The coil operates on 12 VDC with a power consumption of 1.5 watts and a resistance of 120 ohms. Key electrical parameters include a must-operate voltage of 8.4 VDC and a must-release voltage of 1.2 VDC. The unit utilizes silver tin oxide contacts and supports a maximum switching voltage of 75 VDC.

Relay Automotive Feature Summary

• Fully sealed construction for environmental protection
• High current capacity suitable for automotive loads
• Quick-connect terminal style for easy installation

Relay Automotive Applications

• Automotive lighting circuits
• Motor control systems
• General automotive accessory power distribution

Relay Automotive Procurement Notes

Verify the specific part number suffix to ensure compatibility with required coil voltage and contact configuration. Confirm that the quick-connect terminal dimensions match the existing harness or socket infrastructure. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the thermal requirements of the intended installation environment.

Relay Automotive Selection Notes

Select this component when a robust, sealed relay is needed for 12-volt automotive systems requiring up to 30 amps. Consider the SPST-NO configuration for simple on/off control of high-power devices. Evaluate the physical mounting constraints as this model typically requires a base or bracket. Compare against higher-capacity models in the A-series if load currents exceed the 30-amp rating.

Relay Automotive Part Context

This relay belongs to the A11 series from CIT Relay and Switch, a line dedicated to automotive-grade switching solutions. The series is characterized by its durability and ability to handle significant electrical loads in harsh environments. The A11 variant specifically offers a balance of compact size and high current handling, making it a standard choice for vehicle manufacturers and aftermarket accessories.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A11 series relays with identical coil voltages and contact ratings. Verify that any replacement maintains the same terminal type and sealing specifications. Cross-reference with equivalent models from other manufacturers only if pinout and electrical characteristics are fully compatible.
