• Color-coded marking field allows for clear circuit identification and maintenance traceability.
• Flame-retardant polycarbonate housing meets UL94V-0 safety standards for industrial applications.

Applications

• Industrial control cabinet wiring
• Signal distribution panels
• Power supply interconnections

Procurement Notes

Verify the specific ordering code against the manufacturer's official datasheet to ensure compatibility with required conductor cross-sections and voltage ratings. Confirm that the packaging quantity matches project requirements, as bulk orders may differ from single-unit purchases. Check for any recent regulatory updates or RoHS compliance statements directly from Phoenix Contact documentation before finalizing procurement decisions.

Selection Notes

Select this component based on its 7.62 mm pitch and 24 A current capacity relative to the circuit design requirements. Ensure the operating environment temperature range aligns with the specified limits of the polycarbonate housing. Consider the need for auxiliary components such as bridging elements or end brackets if multiple units are installed adjacent to each other in dense panel layouts.
