1578457

Overview

The Phoenix Contact 1578457 is a PCB terminal block designed for secure electrical connections in control cabinet environments. It features a nominal current rating of 24 A and a rated voltage of 630 V, ensuring reliable performance under standard industrial conditions. The component utilizes a screw connection method with a pitch of 5.08 mm, accommodating wire cross-sections from 0.25 mm² to 4 mm² for solid or stranded conductors. It is constructed from polycarbonate (PC) material, providing UL 94 V-0 flame resistance and high dielectric strength. The device supports a two-pole configuration, allowing for compact mounting on printed circuit boards while maintaining necessary isolation distances.

Feature Summary

• Screw connection mechanism ensures robust mechanical stability for conductor retention
• Polycarbonate housing provides inherent flame retardancy and electrical insulation
• Compact pitch design facilitates dense mounting arrangements on PCB layouts

Applications

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

Procurement Notes

Verify the specific ordering code against the manufacturer's official datasheet to confirm pin configuration and accessory compatibility. Ensure that the selected variant matches the required voltage class and current carrying capacity for the intended circuit application. Cross-reference technical drawings for mounting dimensions to guarantee physical fit within the enclosure design constraints.

Selection Notes

Select this component based on the required pole count and wire gauge compatibility for the target application. Evaluate the environmental conditions, such as temperature range and vibration levels, to ensure the terminal block meets operational durability standards. Confirm that the voltage rating exceeds the maximum system potential to maintain safety compliance and prevent dielectric breakdown during operation.

Part Context

This terminal block belongs to the Phoenix Contact universal series, characterized by modular design principles and standardized dimensions. The series allows for mixing different pole counts and colors within the same mounting rail or PCB layout. It is engineered to integrate seamlessly with associated accessories like bridging elements and marking systems, supporting scalable infrastructure development in electrical engineering projects.

Replacement Considerations

Consult the manufacturer's replacement guide for direct equivalents. Verify that any substitute part maintains identical pitch, current rating, and voltage classification. Ensure mechanical footprint compatibility to avoid redesigning the printed circuit board or mounting structure when swapping components.
