Product Description
Marine vessels operating on remote coastlines demand weatherproof shore power systems that maintain electrical integrity through salt spray, UV exposure, and constant deck vibration. The PowerFit 400A Panel Drain connector in red provides the robust panel-mount architecture for permanent installation on vessel power distribution enclosures and shore power pedestals serving oceangoing yachts, research vessels, and commercial fishing fleets. Built with silver-plated brass contacts rated for 400A continuous current and featuring an innovative plastic end cap that shields live electrical surfaces from accidental contact, this connector delivers the IP67 sealing protection and mechanical stability required for unattended operation in harsh maritime environments.

Compatibility
The PowerFit 400A Panel Drain connector is compatible with major brands of single-pole power connector systems rated for marine service. Its M12 threaded post interface and push-and-twist mating mechanism follow standardized connection geometry across certified suppliers. Confirm that your Panel Source connector carries appropriate marine-grade certifications (corrosion-resistant materials, salt spray testing) to ensure matched performance in saltwater environments. The color-coded red housing serves as a visual aid to prevent cross-phase connections when working in confined deck spaces.

Frequently Asked Questions
What role does PFPD-1R serve in a power distribution enclosure?
PFPD-1R is a KUPO PowerFit 400A panel drain connector with a red housing, identifying Line 1 (L1) under Australia 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.
What current and voltage ratings make PFPD-1R suitable for permanent distribution?
PFPD-1R is rated for 400 amperes continuous with 120mm² cable. The maximum voltage rating is 1000V AC or DC. The insulation resistance exceeds 5000 megaohms at 500V AC, and the test voltage rating of 4500V AC provides substantial safety margin. Its short-time withstand rating is 16 kA for 1 second.
How does the red color coding on PFPD-1R help identify L1 on the jobsite?
Australian wiring standards designate red as the Line 1 (L1) conductor. The Australian three-phase color set is red (L1), white (L2), and blue (L3). Red L1 is also used in parts of New Zealand and some Asia-Pacific regions that follow Australian electrical practices. On the Panel Drain, the red 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. Using the correct L1 color prevents phase rotation errors that can damage three-phase motors and sensitive equipment.
How does PFPD-1R meet safety requirements for panel-mounted power distribution?
PFPD-1R is TÜV Rheinland certified to IEC 61984 (ID 1111322264) under Type Approval, Safety, and Regular Production Surveillance categories. It also holds CB and UKCA certificates, and carries CE marking, RoHS compliance (Restriction of Hazardous Substances), and REACH compliance. The housing material achieves a UL94-V0 flammability rating, which is the top rating in the UL94 vertical burn (V) series, meaning the material self-extinguishes within 10 seconds with no flaming drips. For permanent installations, the IP2X 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-1R in a panel?
Installing PFPD-1R requires a 47.5mm diameter cutout in the enclosure panel. The connector mounts through four 5.5mm fixing holes on a 42 x 42mm square, 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. IP2X 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.
Can PFPD-1R work alongside connectors from other brands in a distribution panel?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The IP67 rating means production does not stop for rain, and the push-and-twist connection resists accidental disconnection from cable tension or foot traffic across cable runs. For L1 circuits using Australia color conventions, the red PFPD-1R ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
