Frequently Asked Questions
PFPD-EGN FAQ
What role does PFPD-EGN serve in a power distribution enclosure?
PFPD-EGN is a KUPO PowerFit 400A panel drain connector with a green housing, designated for the Protective Earth (PE) conductor. 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 mining and tunneling applications. Underground mining and tunnel construction require power distribution in confined, humid, dusty environments where safety standards are especially stringent and equipment must withstand harsh mechanical treatment.
What are the electrical specifications of PFPD-EGN for panel installations?
PFPD-EGN 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 silver-plated brass contact achieves a contact resistance of just 0.1 milliohms, significantly reducing resistive heating compared to plain brass contacts at sustained high-current loads. This low resistance is particularly important for PE circuits carrying continuous earth current.
How does PFPD-EGN ensure proper earth conductor identification?
Green identifies the Protective Earth (PE) conductor across virtually every international standard: NEC, IEC, Australian, old UK, and Chinese GB. Some regions specify green/yellow striped, but solid green is universally recognized as earth ground. Ground conductor integrity is the most critical safety element in any power distribution system. On the Panel Drain, the green 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. A distinct green connector ensures the safety earth is never confused with a current-carrying phase or neutral conductor. This is non-negotiable for personnel safety and equipment protection.
What certifications make PFPD-EGN suitable for permanent installation?
PFPD-EGN 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.
How is PFPD-EGN installed in a power distribution enclosure?
Installing PFPD-EGN 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 equipment and enclosures is PFPD-EGN designed to mount in?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. IP67 dust-tight and waterproof protection is critical underground, the 35.5 kA short circuit rating provides safety margin in high-fault-current mining distribution, and the non-conductive housing eliminates accidental current paths. For PE circuits using Universal (all regions) color conventions, the green PFPD-EGN ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
