Procurement Notes

Verify the specific part number 1187192 against official Phoenix Contact documentation to confirm compatibility with existing KNX bus architectures. Ensure that the required wire cross-sections fall within the 0.14 mm² to 2.5 mm² range supported by the push-in terminals. Confirm that the 500 V nominal voltage rating meets the system requirements before procurement.

Selection Notes

Select this component when integrating KNX bus systems requiring standardized color coding and internal bridging capabilities. The push-in connection method offers efficient installation without tools. Consider the 24-position capacity and NS35 rail mounting compatibility when designing control panels for building automation applications.

Part Context

This distribution block belongs to the PTFIX 1.5 series from Phoenix Contact, specifically engineered for KNX applications. It serves as a critical interface component for organizing and distributing signals within building management systems.
