Product Description
European IEC 60446 standards assign grey to the L3 (Phase C) conductor in three-phase power systems. The PowerFit 400A Panel Source in grey serves panel builders, OEM (Original Equipment Manufacturer) integrators, and electrical contractors working on European-standard installations that require permanent, high-current single-pole inlets. The connector's short circuit capacity of up to 35.5 kiloamperes and insulation resistance greater than 5000 megohms at 500V AC provide the electrical performance margins required for safety-critical power distribution infrastructure, while the patent key-release pin simplifies service access during planned outages.

Compatibility
The PowerFit 400A Panel Source connector is compatible with major brands of single-pole power connector systems. Its M12 threaded post interface and push-and-twist mating mechanism with key-release pin ensure standardized connection geometry across certified suppliers. The male contact mates with PowerFit Line Drain and Panel Drain connectors. Verify mechanical and electrical specifications with your mating connector manufacturer to confirm impedance matching and safe operating parameters. Use the color-coded and mechanically keyed design as a visual safeguard to prevent cross-phase connection errors during installation or reconfiguration.

Frequently Asked Questions
PFPS-3GY FAQ
What is PFPS-3GY and why is it the starting point of power distribution?
PFPS-3GY is a KUPO PowerFit 400A panel source connector with a grey housing, identifying Line 3 (L3) under Europe and UK (IEC 60446) conventions. Mounted permanently at generator outputs, main panels, and power supply enclosures, it is the origin point from which power flows outward through the PowerFit system. Despite being panel-mounted, it retains the key-release mechanism for convenient field disconnection. It is commonly deployed in theme park and entertainment venue applications. Permanent outdoor entertainment installations demand connectors that survive years of sun exposure, seasonal weather changes, and constant operation.
How much current can PFPS-3GY supply from a distribution panel?
PFPS-3GY is rated for 400 amperes continuous with 120mm2 cable, scaling to 660 amperes with 240mm2 cable. The maximum voltage rating is 1000V AC or 1500V DC. The M12 threaded post termination accepts conductors through a brass nut and washer assembly, tightened to a maximum of 12 to 14 N/m. The four-point flange mount with 5.5mm fixing holes distributes mechanical load across the panel surface.
What does the grey housing on PFPS-3GY represent under Europe and UK (IEC 60446) standards?
Grey identifies Line 3 (L3) under IEC 60446, completing the European three-phase color set of brown (L1), black (L2), grey (L3). Grey L3 is standard across all EU member states, the UK (post-2004), and countries that have adopted IEC harmonized wiring colors. On the Panel Source, the grey housing is visible on the connector face at the power origin point. Color coding at the source end of the distribution chain is especially important because phase assignment errors at the panel propagate through every downstream connection. In large-scale European venue installations, grey L3 connectors provide visual confirmation that all three phases of the IEC set are present and correctly assigned.
What independent testing has PFPS-3GY undergone?
PFPS-3GY is TUV Rheinland certified (ID 1111303479) under Type Approval, Safety, and Regular Production Surveillance categories. It also carries CE marking, RoHS compliance (Restriction of Hazardous Substances), and REACH compliance. The housing material achieves a UL94-V0 flammability rating, which is the highest classification for vertical flame resistance in plastics, meaning the material self-extinguishes within 10 seconds with no flaming drips. As the power origin point, the Panel Source undergoes the same TUV safety evaluation as the full PowerFit system, including the key-release mechanism and panel-mount retention.
What panel cutout and mounting specifications does PFPS-3GY require?
The PFPS-3GY mounts through a 42 x 42mm panel cutout using four 5.5mm fixing holes. The M12 threaded post secures to the panel with the included brass nut and washer at 12 to 14 N/m maximum torque. Despite being a permanent panel-mount connector, PFPS-3GY retains the PowerFit key-release mechanism, allowing field technicians to disconnect mating Line Drain connectors without tools. IP 2X finger protection and a plastic end cap protect the contacts when no mating connector is present. The Panel Source has a 55.3mm flange width and 50.7mm total depth, with a 42.5mm body diameter. It is shallower than the Panel Drain, requiring less clearance behind the panel.
How does PFPS-3GY integrate with existing power infrastructure in theme park and entertainment venue settings?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The flame-retardant thermoplastic housing resists UV degradation, TUV Rheinland certification meets European safety requirements for permanent installations, and the 500-cycle mating life supports seasonal maintenance schedules. For L3 circuits using Europe and UK (IEC 60446) color conventions, the grey PFPS-3GY ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
