A2F1CSQ24VDC1.9D

Relay Automotive Overview

The A2F1CSQ24VDC1.9D is an automotive relay manufactured by CIT Relay and Switch, designed for chassis mounting applications. It features a single-pole double-throw (SPDT) contact configuration with one Form C. The coil operates at 24 VDC, requiring a maximum of 16.8 VDC to engage. The contacts support a switching current of up to 40 Amps with a maximum switching voltage of 75 VDC. This component includes an integrated diode for coil protection.

Relay Automotive Feature Summary

• SPDT contact configuration providing versatile switching capabilities
• High current capacity suitable for demanding automotive loads
• Integrated coil protection diode included in design

Relay Automotive Applications

• Automotive electrical systems
