Frequently Asked Questions
PFPD-3BL FAQ
What kind of installations require PFPD-3BL?
PFPD-3BL is a KUPO PowerFit 400A panel drain connector with a blue housing, identifying Line 3 (L3) under Multiple conventions (NEC, Australian, UK Old) conventions. Mounted permanently in enclosures and distribution boxes, it serves as the final destination in the PowerFit electric direction flow, where incoming power from Line Source connectors enters the downstream equipment. The four-point flange mount and M12 threaded post ensure vibration-resistant installation. It is commonly deployed in emergency and disaster response applications. Emergency power deployment happens in the worst possible conditions: flooded areas, debris fields, extreme weather.
What current and voltage ratings make PFPD-3BL suitable for permanent distribution?
PFPD-3BL 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 insulation resistance exceeds 5000 megaohms at 500V AC, and the test voltage rating of 4500V AC provides substantial safety margin. The short circuit rating of up to 35.5 kiloamperes means the connector can withstand fault conditions without catastrophic failure.
How does the blue color coding on PFPD-3BL help identify L3 on the jobsite?
Blue as L3 enjoys unusually broad cross-convention agreement. It represents L3 in North American NEC (black/red/blue), Australian (red/white/blue), and old UK (red/yellow/blue) standards. This makes blue L3 one of the most universally understood phase colors in the world. On the Panel Drain, the blue color is visible on the connector face that protrudes from the enclosure panel. When multiple PowerFit connectors are mounted side by side in a distribution box, the color-coded faces create a clear visual map of the phase layout for incoming connections. The dual identity of blue (L3 in NEC/Australian vs Neutral in IEC) makes proper phase-encoded labeling essential on international projects.
How does PFPD-3BL meet safety requirements for panel-mounted power distribution?
PFPD-3BL 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. For permanent installations, the IP 2X finger protection prevents accidental contact with live parts when the connector face is exposed, and the four-point flange mount exceeds mechanical retention requirements.
What are the mounting requirements for PFPD-3BL in a panel?
Installing PFPD-3BL requires a 42 x 42mm cutout in the enclosure panel. The connector mounts through four 5.5mm fixing holes on its flange, distributing clamping force evenly for vibration resistance. The M12 threaded post accepts the brass nut and washer, tightened to a maximum of 12 to 14 N/m. IP 2X finger protection is built into the connector face, preventing accidental contact with live parts when no mating connector is inserted. A plastic end cap protects the contacts during storage and transport. The Panel Drain has a 55.0mm flange width and 72.2mm total depth, with a 37.0mm body diameter. The flange provides a generous mounting surface for secure enclosure attachment.
What sets PFPD-3BL apart from conventional panel-mount power connectors?
PFPD-3BL offers several meaningful improvements over conventional single-pole power connectors: IP 2X finger protection prevents accidental contact with live parts when the connector face is exposed; IP67 protection when mated provides dust-tight and waterproof sealing that most single-pole connectors lack; the 1000V AC / 1500V DC voltage rating exceeds the typical 600V maximum of traditional alternatives; silver-plated brass contacts deliver lower contact resistance (0.1 milliohms) than plain brass. These features, combined with TUV Rheinland certification and the phase-encoded blue housing for L3 identification, make PowerFit a generation ahead of traditional designs.
