Frequently Asked Questions
PFLD-NW-S120M40A FAQ
What is the PFLD-NW-S120M40A and what role does it play in a PowerFit system?
PFLD-NW-S120M40A is a KUPO PowerFit 400A line drain connector with a white housing, designated for the Neutral (N) conductor under North America (NEC) conventions. As the drain side of an inline cable connection, it receives the mating source contact and provides a sealed, IP67-rated junction when coupled. The white housing enables instant visual identification of the N conductor across cable runs. It is commonly deployed in agricultural and greenhouse operation applications. Agricultural power distribution faces moisture from irrigation, fertilizer chemicals, temperature extremes from greenhouse heating, and often rural locations far from electrical supply houses.
What are the electrical ratings and wire capacity of PFLD-NW-S120M40A?
PFLD-NW-S120M40A 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 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 N circuits carrying continuous neutral current.
What does the white housing on PFLD-NW-S120M40A indicate about its neutral assignment?
White identifies the Neutral conductor under North American NEC conventions. White is universally recognized across the USA and Canada as neutral, and using any other color for neutral in NEC-governed installations typically requires special marking or approval. On the Line Drain connector, the white housing is visible along the full 190mm body length, making N identification easy even when cables are bundled tightly. The ergonomic rubber grip section also carries the color, so technicians can identify the phase while handling the connector. A dedicated white PowerFit connector for the neutral return path eliminates guesswork in three-phase-plus-neutral distribution systems.
What certifications and safety ratings does PFLD-NW-S120M40A carry?
PFLD-NW-S120M40A 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. The silicone O-ring seal contributes to the IP67 rating when mated, meaning the connection is fully protected against dust ingress and temporary immersion in water up to 1 meter for 30 minutes.
Is PFLD-NW-S120M40A compatible with single-pole connectors from other manufacturers?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The silicone O-ring seals against irrigation moisture, the thermoplastic housing resists agricultural chemical exposure, and the push-and-twist mechanism does not require specialized tools that might not be available in remote locations. For N circuits using North America (NEC) color conventions, the white PFLD-NW-S120M40A ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
