1554831

Overview

The Phoenix Contact 1554831 is a PCB terminal block designed for secure electrical connections in industrial control environments. It features a nominal current rating of 24 A and supports a rated voltage of 630 V. The component utilizes a screw connection method with a pitch of 7.62 mm, accommodating conductors ranging from 0.5 to 2.5 mm². Constructed with UL94V-0 rated polycarbonate housing, it ensures flame retardancy and high dielectric strength. The unit includes a marking field for circuit identification and offers a compact footprint suitable for dense panel layouts.

Feature Summary

• Screw connection mechanism provides reliable mechanical clamping force for stranded and solid wires.
• Polycarbonate housing meets UL94V-0 flammability standards for enhanced safety.
• Integrated marking field allows for clear circuit identification during installation.

Applications

• Industrial control cabinet wiring
• Signal distribution in automation systems
• Power supply interconnections

Procurement Notes

Verify the specific ordering code against the official Phoenix Contact catalog to ensure compatibility with existing assembly requirements. Confirm that the voltage and current ratings align with the system design specifications before procurement. Check for any required accessories such as jumper elements or end brackets that may be necessary for the specific application setup.

Selection Notes

Select this component based on the required conductor cross-section and pitch compatibility with the printed circuit board layout. Ensure the environmental conditions within the enclosure do not exceed the specified temperature range for the polycarbonate material. Consider the mounting orientation and available space when integrating the terminal block into the overall system architecture.

Part Context

This part belongs to the Phoenix Contact universal series of PCB terminal blocks, which are widely used in European industrial automation. The series is characterized by its modular design and consistent pitch dimensions, allowing for flexible configuration options. Components in this line are typically certified for global compliance, facilitating international deployment in various regulatory environments.

Replacement Considerations

Direct replacements must match the 7.62 mm pitch and 24 A current rating. Verify housing width and height constraints to ensure physical fitment. Cross-reference with Phoenix Contact's alternative product lines if specific locking mechanisms or additional features are required for the application.
