1111440500

Overview

The Weidmüller 1111440500 is a terminal block connector designed for secure electrical connections in industrial control panels. It features a screw connection method suitable for stranded and solid wires, ensuring reliable contact under vibration. The component supports wire cross-sections typically ranging from 0.2 to 2.5 mm², accommodating various cable gauges common in automation systems. Constructed with durable materials, it meets relevant safety standards for insulation resistance and dielectric strength.

Feature Summary

• Screw connection mechanism for robust wire retention
• Compatible with standard DIN rail mounting configurations
• Designed for high-vibration industrial environments

Applications

• Industrial control panel wiring
• Automation system interconnections
• Machine tool electrical assemblies

Procurement Notes

Verify the specific order number against official Weidmüller catalogs to ensure compatibility with existing DIN rail profiles and wire gauge requirements. Confirm insulation voltage ratings match the application's operational conditions. Request certified test reports if required by facility safety protocols before bulk procurement.

Selection Notes

Select this model based on its screw termination style which offers higher mechanical stability compared to push-in types in high-vibration settings. Ensure the pitch matches adjacent terminals in the assembly layout. Consider environmental factors such as temperature range and chemical exposure when validating material suitability for the specific installation site.

Part Context

This component belongs to Weidmüller's terminal block series, widely used in European industrial standards. It complements other connectors in the same family that share similar mounting dimensions but may differ in pole count or wire capacity. The design emphasizes modularity and ease of maintenance within complex electrical networks.

Replacement Considerations

Direct substitutes must match the pitch, height, and connection type. Verify equivalent part numbers from authorized distributors only. Generic equivalents may lack the specific certification approvals required for regulated industries.
