Product Description
Overview
United Kingdom electrical infrastructure using legacy color-coding standards requires permanent power distribution connectors that maintain backward compatibility with historical wiring conventions while delivering modern safety and reliability. The PowerFit 400 A Panel Drain connector in yellow (Phase 2 / L2 UK Old) provides the enclosure-mount architecture for secondary phase distribution in UK industrial facilities, heritage buildings, and heritage electrical systems transitioning to modern standards. Operating at 400 A continuous with silver-plated brass contacts rated for 500 mating cycles, this connector bridges the gap between older UK electrical conventions and current European IEC standards, offering the patent key-release pin for safe disconnection and plastic end cap protection against incidental contact with live electrical surfaces.

- Patent key-release pin enables UK technicians to safely disconnect secondary phase feeds without additional tools
- Plastic end cap over drain interface provides IP 2X finger protection in high-density industrial electrical rooms
- Push-and-twist locking mechanism prevents vibration-induced separation in operating machinery environments
- Silver-plated brass contact delivers 0.1 mOhms contact resistance across continuous UK industrial power cycles
- Non-conductive UL94-V0 thermoplastic housing meets UK electrical safety standards for heritage and modern installations
- IP67 rating while mated protects against moisture and dust ingress from UK industrial facility conditions
- Maximum nut torque: 12 to 14 N/meter ensures secure mounting without risk of rework
- Yellow color codes as Phase 2 (L2) under older UK wiring regulations (BS 7671 pre-2006)

Match standards and compliance requirements to the local electrical code before installation.
Applications
Suitable for UK industrial plant electrical distribution systems using legacy color-coding conventions, heritage building electrical infrastructure retrofits maintaining older UK wiring standards, manufacturing facilities transitioning from older to modern UK electrical standards, industrial machinery control cabinet distribution for UK-based operations, railway infrastructure and station electrical distribution systems using UK standards, hospital and medical facility electrical systems with established UK color-coding, and museum and cultural heritage site electrical system maintenance and upgrade projects.
Compatibility
The PowerFit 400 A Panel Drain connector is compatible with major brands of single-pole power connector systems used in UK industrial and heritage electrical infrastructure. Its M12 threaded post interface and push-and-twist mating mechanism follow standardized connection geometry across certified suppliers. Verify that your Panel Source connector carries UK certifications and is rated for legacy or modern color-coding standards. The yellow color housing complies with older UK wiring regulations (BS 7671 pre-2006) and facilitates transition planning to modern IEC 60446 standards.

Frequently Asked Questions
How does PFPD-2Y function as the endpoint of a PowerFit power chain?
PFPD-2Y is a KUPO PowerFit 400 A panel drain connector with a yellow housing, identifying Line 2 (L2) under UK (Old, pre-2004) 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 data center maintenance applications. During data center expansion or maintenance windows, temporary power must be distributed with absolute reliability.
What are the electrical specifications of PFPD-2Y for panel installations?
PFPD-2Y is rated for 400 amperes continuous with 120 mm² cable, scaling to 660 amperes with 240 mm² cable. The maximum voltage rating is 1000 V AC or 1500 V DC. The silver-plated brass contact achieves a contact resistance of just 0.1 mOhms, 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.
How does the yellow color coding on PFPD-2Y help identify L2 on the jobsite?
Yellow identifies L2 under the legacy UK wiring color code (red/yellow/blue for L1/L2/L3) used before the 2004 harmonization to IEC standards. Legacy UK installations, some Commonwealth countries, and specialty applications still use this color scheme. On the Panel Drain, the yellow 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. When maintaining or extending pre-2004 UK installations, matching the existing yellow L2 convention prevents confusion between old and new color systems.
What certifications make PFPD-2Y suitable for permanent installation?
PFPD-2Y 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 equipment and enclosures is PFPD-2Y designed to mount in?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The 0.1 milliohm contact resistance minimizes heat generation at connection points, the 500-cycle mating rating supports repeated connect/disconnect during maintenance, and the 1000 V AC / 1500 V DC rating provides margin for high-voltage DC distribution architectures. For L2 circuits using UK (Old, pre-2004) color conventions, the yellow PFPD-2Y ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
