1616977-6

Overview

The TE Connectivity 1616977-6 is a hermetically sealed, single-pole single-throw (SPST) contactor rated for 600 amperes. Designed for high-power switching applications, it features a robust construction suitable for demanding environments. The component utilizes a specific coil voltage configuration to actuate the contacts, ensuring reliable operation under specified electrical loads. Its hermetic sealing provides protection against environmental contaminants, making it suitable for aerospace and defense sectors where reliability is critical.

Feature Summary

• Hermetically sealed construction for environmental protection
• Single-pole single-throw (SPST) contact configuration
• High current rating of 600 amperes
• Designed for high-power switching applications

Applications

• Aerospace power distribution systems
• Defense vehicle electrical architectures
• Marine high-current switching circuits

Procurement Notes

Verify the exact coil voltage requirements against the system design before procurement, as variants exist within the AH600 series. Confirm that the hermetic seal integrity meets the specific environmental standards required for the deployment location. Ensure mounting hardware compatibility with the contactor's base structure. Cross-reference the part number suffix to confirm the specific terminal style and coil specification intended for the application.

Selection Notes

Select this component when a hermetically sealed SPST contactor with a 600A capacity is required. It is appropriate for applications necessitating high reliability in harsh environments. Consider the physical dimensions and mounting constraints during selection. Evaluate the coil drive circuitry to ensure it matches the specific voltage variant of the 1616977-6 model. This part is distinct from non-hermetic alternatives in the same current class.

Part Context

This part belongs to the AH600 series of hermetic contactors manufactured by TE Connectivity Aerospace, Defense and Marine. These components are engineered for mission-critical applications where standard commercial relays would fail due to environmental stress. The series offers various configurations tailored for different voltage and current requirements within the aerospace and defense sectors.

Replacement Considerations

Direct replacements must match the 600A rating, SPST configuration, and hermetic sealing. Verify coil voltage compatibility with existing control circuits. Physical footprint and terminal alignment must be confirmed. Non-hermetic equivalents may not provide sufficient environmental protection for the intended use case.
