1SNA400772R1300

Overview

The TE Connectivity 1SNA400772R1300 is a grounding terminal block from the ENTRELEC SNA series. It features a green and yellow color scheme for earth identification and utilizes a screw clamp connection method. The component accepts a wire range of 4-00 AWG per UL standards and maintains a 22 mm spacing between terminals. Designed as a single-deck unit, it incorporates a built-in separator with closed sides to ensure electrical isolation.

Feature Summary

• Green and yellow housing for clear ground/earth identification
• Screw clamp connection mechanism for secure wire termination
• Built-in separator design with closed sides on both ends
• Single-deck configuration with 22 mm terminal spacing

Applications

• Industrial control panel grounding systems
• Electrical cabinet earthing busbars
• Machinery safety grounding connections

Procurement Notes

Verify the specific part number against official TE Connectivity documentation to confirm compatibility with existing DIN rail mounting systems. Ensure that the required wire gauge falls within the specified 4-00 AWG range for proper termination. Cross-reference the green and yellow color coding requirements with local electrical safety standards before procurement.

Selection Notes

Select this component when a dedicated grounding point with high current capacity is required in a compact space. The screw clamp design offers reliable mechanical retention for larger conductors compared to spring mechanisms. Consider the 22 mm pitch when planning layout density within the enclosure or distribution board.

Part Context

This part belongs to the TE Connectivity ENTRELEC SNA series, which provides modular terminal solutions for industrial applications. The SNA line is known for its robust construction and standardized dimensions, facilitating easy integration into existing electrical infrastructure and ensuring consistent performance across various equipment types.

Replacement Considerations

Consult official TE Connectivity substitution guides for verified equivalents. Generic alternatives may not match the specific 22 mm spacing or closed-side separator design.
