1400421

Overview

The Phoenix Contact 1400421 is a PCB terminal block designed for secure electrical connections within control cabinets and industrial automation systems. It features a nominal current rating of 17.5 A and supports a rated voltage of up to 630 V. The component utilizes a screw connection method with a pitch of 5.08 mm, accommodating wire cross-sections ranging from 0.25 mm² to 1.5 mm² solid or stranded wires. Constructed with a polycarbonate (PC) housing that meets UL 94 V-0 flammability standards, it ensures reliable insulation and durability under demanding operational conditions.

Feature Summary

• Utilizes a robust screw connection mechanism for secure wire termination without the need for additional tools beyond standard drivers.
• Features a compact design with a 5.08 mm pitch, allowing for high-density mounting on printed circuit boards.
• Housing material provides high mechanical stability and thermal resistance suitable for industrial environments.

Applications

• Industrial control cabinet wiring
• Automation system signal distribution
• Power supply unit interconnections

Procurement Notes

Verify the specific ordering code against the official Phoenix Contact catalog to ensure compatibility with required accessories such as jumper strips or marking systems. Confirm that the selected variant matches the necessary certification requirements for your target market, including CE and UL approvals. Cross-reference the technical datasheet for precise mounting dimensions and torque specifications before integration into the final assembly design.

Selection Notes

Select this component based on the required current carrying capacity and voltage isolation levels for the specific circuit application. Ensure the PCB layout accommodates the 5.08 mm pitch and the physical footprint of the terminal block. Consider environmental factors such as temperature range and vibration resistance when determining suitability for the intended installation location.

Part Context

This terminal block belongs to the Phoenix Contact series of PCB connectors designed for general-purpose industrial applications. It is part of a broader family of components offering various pitches and current ratings, allowing engineers to standardize connector types across different modules within a single control system architecture.

Replacement Considerations

When replacing existing components, verify that the substitute part matches the 5.08 mm pitch and identical housing dimensions to fit the existing PCB footprint. Ensure the new component supports the same wire cross-section range and maintains equivalent electrical ratings for voltage and current to prevent performance degradation or safety hazards.
