Product Description
North American three-phase systems under NEC standards use red to identify the L2 (Phase B) conductor. The PowerFit 400A Panel Source in red serves as the fixed-panel power inlet for generator connection boxes, portable power distribution units, and entertainment industry dimmer racks where 400A per phase is standard. The M12 threaded post mount with brass nut and spring washer provides vibration-resistant panel attachment, and the 42mm x 42mm cut-out dimension with four diameter 5.5mm fixing holes matches standard industrial panel preparation specifications.

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-2R FAQ
What is PFPS-2R and why is it the starting point of power distribution?
PFPS-2R is a KUPO PowerFit 400A panel source connector with a red housing, identifying Line 2 (L2) under North America (NEC) 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 construction site applications. Construction power distribution deals with dust, debris, rain, rough handling by crews, and the constant repositioning of equipment as the site evolves.
What are the power handling specifications of PFPS-2R?
PFPS-2R 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.
What does the red housing on PFPS-2R represent under North America (NEC) standards?
Red marks Line 2 (L2) under North American NEC conventions. In a standard three-phase system, the color sequence is black (L1), red (L2), blue (L3). Red L2 is one of the most commonly ordered phase variants for US and Canadian power distribution, appearing in virtually every multi-phase temporary power installation. On the Panel Source, the red 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. Red is one of the most visually distinctive colors on a busy event site, helping crews quickly trace the second phase conductor even from a distance.
How is PFPS-2R certified for use as a power source connector?
PFPS-2R 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 makes PFPS-2R installation straightforward for permanent power sources?
The PFPS-2R 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-2R 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.
Can PFPS-2R 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 high-impact thermoplastic housing absorbs punishment, the IP67 seal protects against dust ingress (the '6' in IP67 means dust-tight), and the M40 cable gland secures cables against pull-out. For L2 circuits using North America (NEC) color conventions, the red PFPS-2R ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
