A2H1ASP12VDC1.6

Relay Automotive Overview

The A2H1ASP12VDC1.6 is an automotive relay manufactured by CIT Relay and Switch, featuring a single-pole single-throw normally open (SPST-NO) contact configuration with a 50A rated current capacity. It operates on a 12VDC coil voltage with a maximum switching voltage of 75VDC. The unit utilizes silver tin oxide contacts and supports quick connect terminals for mounting. Designed for robust performance, it functions within a temperature range of -40°C to 125°C and includes a sealed construction to protect against environmental factors.

Relay Automotive Feature Summary

• High current switching capability up to 50A
• Sealed construction for environmental protection
• Quick connect terminal mounting style

Relay Automotive Applications

• Automotive electrical systems
• Industrial control circuits
• Heavy equipment power management

Relay Automotive Procurement Notes

Verify the specific contact rating requirements against the 50A SPST-NO specification before procurement. Confirm that the 12VDC coil voltage aligns with the system's available supply voltage. Ensure the quick connect terminal interface matches existing wiring harnesses. Check for compliance with relevant automotive industry standards if used in vehicle applications.

Relay Automotive Selection Notes

Select this component when a high-current single-channel switch is required in space-constrained automotive or industrial environments. The 50A rating distinguishes it from lower-capacity alternatives in the series. Consider the operating temperature range and sealed design for harsh conditions. Verify compatibility with standard relay sockets if socket-based installation is preferred over direct wiring.

Relay Automotive Part Context

This part belongs to the A2 series of automotive relays from CIT Relay and Switch, known for compact size and high switching capacity. The series offers various contact configurations and coil voltages to suit different circuit requirements. The A2H1ASP variant specifically provides enhanced current handling compared to standard signal relays, making it suitable for powering high-draw accessories.

Relay Automotive Replacement Considerations

Equivalent parts include A2M1USP12VDC1.6 and A2S1ASQ12VDC1.6, which share similar form factors and coil specifications but may differ in contact ratings or terminal styles. Verify mechanical fit and electrical parameters before substitution.
