Product Description
Three-phase European installations using IEC standards assign black to the L2 (Phase B) conductor. The PowerFit 400A Panel Source in black for L2 service provides equipment manufacturers and panel builders with a high-current inlet that handles 400A continuous loads through silver-plated brass contacts, achieving just 0.1 milliohms contact resistance for efficient power transfer. The key-release pin mechanism keeps the connection mechanically secure during operation while still allowing intentional tool-free release during scheduled maintenance, and the IP67 rating when mated protects against dust and water ingress in outdoor environments.

Applications
- Three-phase power distribution panels requiring dedicated L2 phase inlets
- Dimmer rack and lighting control enclosures for theatrical and concert touring systems
- Industrial manufacturing equipment with balanced three-phase power requirements
- Power management systems for mining and heavy industry operations
- UPS (Uninterruptible Power Supply) bypass panels and transfer switch enclosures
- Festival and outdoor event power distribution boards with weather-exposed installations

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 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
Where is PFPS-2BK typically installed and what does it feed?
PFPS-2BK is a KUPO PowerFit 400A panel source connector with a black housing, identifying Line 2 (L2) under Europe and UK (IEC 60445) 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.
What electrical capacity does PFPS-2BK provide as a panel source connector?
PFPS-2BK is rated for 400 amperes continuous with 120mm² cable. The maximum voltage rating is 1000V AC or 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 L2 circuits carrying continuous phase current.
What does the black housing on PFPS-2BK represent under Europe and UK (IEC 60445) standards?
Under IEC 60445, black identifies Line 2 (L2). This is the second phase conductor in the European three-phase system of brown (L1), black (L2), gray (L3). For international crews, this is a critical distinction: the same black housing that means L1 in North America means L2 in Europe. On the Panel Source, the black 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. Cross-convention errors between NEC-L1-black and IEC-L2-black are among the most common phase identification mistakes on international projects.
What safety certifications does PFPS-2BK hold for distribution panel use?
PFPS-2BK 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. As the power origin point, the Panel Source undergoes the same TÜV safety evaluation as the full PowerFit system, including the key-release mechanism and panel-mount retention.
What equipment and enclosures is PFPS-2BK designed to mount in?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The 400A continuous rating handles industrial loads, the flame-retardant UL94-V0 housing resists chemical exposure, and the push-and-twist lock prevents vibration-induced disconnection. For L2 circuits using Europe and UK (IEC 60445) color conventions, the black PFPS-2BK ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
How is PFPS-2BK mounted in a distribution panel or generator output?
The PFPS-2BK mounts through a 47.5mm diameter panel cutout using four 5.5mm fixing holes on a 42 x 42mm square. 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-2BK retains the PowerFit key-release mechanism, allowing field technicians to disconnect mating Line Drain connectors without tools. IP2X 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.
