Phoenix Contact

Phoenix Contact is a primary supplier of internal wiring, protection and control components used in IEC 61439 panel assemblies for metering panels, PLC/automation racks and custom-engineered switchboards. Their CLIPLINE terminal block platform (CLIPLINE complete, CLIPLINE 3000 families) delivers feed-through, fuse-disconnect, sensor/actuator, potential-distribution and grounding terminals that enable functional segregation and the Forms of Separation required by IEC 61439-1 (Forms 1 through 4b). COMBICON pluggable and PCB connector systems provide standardized, IEC 61984-compatible mating for field connections and board-level control electronics such as PLCnext and Axioline I/O modules. TRABTECH surge protection devices (SPDs) are engineered to IEC 61643-11 coordination classes and are commonly used to protect metering CT/VT inputs, Ethernet/fieldbus interfaces and power buses against transient surges. Beyond terminals and SPDs, Phoenix Contact supplies control-room power (QUINT POWER and UNO power-supply ranges), interface relays and PSR safety-relay families that integrate with IEC 60947-series motor-control and protection devices. These components are widely used inside type-tested systems (for example, when integrating into SIVACON or MNS assemblies) where the panel builder proves rated currents, temperature-rise and short-circuit withstand for the whole assembly per IEC 61439-1/-2. While Phoenix Contact components themselves are component-certified to standards such as IEC 60947 (controlgear), IEC 61131 (PLC programming environments) and IEC 60079 (selected Ex/Intrinsically Safe modules), the panel’s overall SCCR and Icw depend on coordination with MCCBs or fused isolators compliant with IEC 60947-2 and fuse links to IEC 60269. In practical applications, CLIPLINE terminals support conductor cross-sections from fine-stranded signal wiring up to multi-strand power feeds and are sized to accommodate control-circuit currents (mA to tens of A) through to feeder currents when mated with appropriate busbar and breaker selections. TRABTECH SPDs are available in Type 1/2/3 coordinated topologies for building entrances, distribution and sensitive electronics racks. Phoenix Contact marking and printing systems facilitate traceable, standardized identification required for inspection and maintenance in high-reliability installations. For engineers specifying IEC 61439 panels, Phoenix Contact’s modular connectors, power supplies and protection devices reduce wiring labor, improve maintainability and simplify achieving Forms of Separation and protective device coordination in type-tested and custom assemblies.
