Product Description
Australian and United Kingdom electrical infrastructure requires neutral conductor connections that deliver 400A continuous current while maintaining circuit balance and load distribution across three-phase systems. The PowerFit 400A Panel Drain connector in black (Neutral NBK - Australia/UK Old) provides the enclosure-mount architecture for neutral distribution in multi-phase facilities, ensuring color-coded compliance with Australian electrical standards (AS/NZS 3000) and legacy UK wiring regulations where black identifies the neutral conductor. Operating at 400A continuous with silver-plated brass contacts rated for 500 mating cycles, this connector delivers the patent key-release pin for safe disconnection and plastic end cap protection, serving the critical function of completing return current paths in three-phase power systems.

- Four diameter 5.5mm fixing holes (42mm × 42mm cut-out) accommodate Australian and UK electrical cabinet standards
- Patent key-release pin enables safe disconnection of neutral return paths during load management without tools
- Plastic end cap over female contact provides IP 2X finger protection in high-density multi-phase distribution rooms
- Push-and-twist locking mechanism prevents vibration-induced separation of critical neutral return conductors
- Silver-plated brass contact delivers 0.1 milliohms contact resistance, minimizing neutral point impedance
- Non-conductive UL94-V0 thermoplastic housing meets Australian and UK electrical safety standards
- IP67 rating while mated protects neutral connections against moisture and dust ingress in industrial facilities
- Maximum nut torque: 12 to 14 N/meter ensures secure mounting without risk of rework
- Black color codes as Neutral (N) under Australian (AS/NZS 3000) and UK Old (BS 7671 pre-2006) standards

Frequently Asked Questions
PFPD-NBK FAQ
How does PFPD-NBK function as the endpoint of a PowerFit power chain?
PFPD-NBK is a KUPO PowerFit 400A panel drain connector with a black housing, designated for the Neutral (N) conductor under Australia and 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 touring theatrical production applications. Touring shows load in and load out of different venues on tight schedules, sometimes daily.
What current and voltage ratings make PFPD-NBK suitable for permanent distribution?
PFPD-NBK 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.
How does the black color coding on PFPD-NBK prevent neutral-phase confusion?
Black as Neutral follows Australian wiring conventions and the legacy UK color code (pre-2004 harmonization). In Australia, the standard wiring set includes black for Neutral alongside red (L1), white (L2), blue (L3), and green (Earth). On the Panel Drain, the black 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. Confusing neutral-black (Australian) with phase-black (NEC L1 or IEC L2) can create dangerous neutral-to-phase faults. Phase-encoded connectors prevent this.
How does PFPD-NBK meet safety requirements for panel-mounted power distribution?
PFPD-NBK 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.
Can PFPD-NBK 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 key-release pin enables tool-free disconnect during strike, the push-and-twist connection engages in seconds, and the ergonomic rubber grip reduces hand fatigue during long load-in sessions involving dozens of connections. For N circuits using Australia and UK (Old, pre-2004) color conventions, the black PFPD-NBK ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
