• Sealed construction protects against moisture and dust ingress
• Single Pole Double Throw (SPDT) contact configuration for versatile circuit control

Relay Automotive Applications

• Automotive starter motor circuits
• Heavy-duty accessory power distribution
• Industrial vehicle electrical systems

Relay Automotive Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm if it denotes a specific packaging variant or terminal configuration distinct from the base model. Ensure the 24VDC coil rating matches the system voltage to prevent operational failure. Cross-reference the 50A contact rating with the actual load requirements to guarantee adequate safety margins during peak current draw conditions.

Relay Automotive Selection Notes

Select this component when a high-capacity SPDT switch is required for 24V automotive environments. The sealed design offers protection against harsh conditions where standard relays might fail. Confirm that the physical footprint and pinout are compatible with the intended PCB or socket assembly. Evaluate the thermal management requirements given the high current handling capabilities of the internal contacts.

Relay Automotive Part Context

This part belongs to the A2 series of automotive relays from CIT Relay and Switch, which are engineered for durability in vehicle applications. The series typically includes various coil voltages and contact configurations to support different electrical architectures. The A2H1CCQ24VDC1.6R specifically addresses the need for high-amperage switching in 24V systems, distinguishing it from lower-rated general-purpose relays found in consumer electronics.
