Product Description
Built for field deployment, the PFLD-2W-S120M40A is a 400A single-pole line drain connector that combines rugged construction with straightforward installation. This inline female connector bridges demanding environments with an ergonomic rubber grip and the M40 by 1.5-millimeter cable gland that accepts cables up to 33-millimeter inside diameter through dual sealing bushings. The push-and-twist connection mechanism requires no specialized equipment—a significant advantage when rapid assembly matters and downtime costs money. Supporting both standard 400-ampere and elevated 660-ampere ratings depending on cable gauge, this connector adapts to diverse system configurations while maintaining sealed IP67 performance and compliance with international safety standards.

Applications
The PFLD-2W-S120M40A performs reliably in Australian and regional renewable energy projects, distributed solar installations, microgrid systems, and portable power configurations where field technicians must work efficiently with standard cable glands and hand tools. The 500 mating cycle rating supports commissioning, maintenance, and system expansion without premature wear, while the sealed design protects investments in remote or exposed locations.
Compatibility
This connector is compatible with major brands of single-pole power connectors, enabling straightforward component sourcing and field interchangeability. The push-and-twist connection standard aligns with industry norms, allowing technicians trained on competing systems to assemble KUPO connectors without retraining or specialized equipment procurement.

Frequently Asked Questions
PFLD-2W-S120M40A FAQ
What kind of connector is PFLD-2W-S120M40A and where does it fit in the power chain?
PFLD-2W-S120M40A is a KUPO PowerFit 400A line drain connector with a white housing, identifying Line 2 (L2) under Australia 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 L2 conductor across cable runs. It is commonly deployed in marine and shipyard applications. Shipyard and dockside power connections face salt spray, high humidity, and the corrosive marine environment.
What voltage and amperage is PFLD-2W-S120M40A rated for?
PFLD-2W-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 M40 cable gland accommodates cables through two included rubber bushings (inner diameter 23mm and 33mm), and the R120 reduction sleeve (brass with silver plating) handles conductor diameters up to 16.50mm. Set screws require a minimum torque of 10.5 N/m for reliable termination.
What does the white housing on PFLD-2W-S120M40A represent under Australia standards?
White as L2 follows Australian wiring conventions, where the three-phase set is red (L1), white (L2), blue (L3). This variant specifically serves Australian, New Zealand, and related Asia-Pacific markets. On the Line Drain connector, the white housing is visible along the full 190mm body length, making L2 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. The stark visual contrast between white L2 and the darker L1/L3 conductors makes phase tracing straightforward in Australian installations.
What safety standards govern the design and manufacture of PFLD-2W-S120M40A?
PFLD-2W-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.
What makes PFLD-2W-S120M40A practical for field assembly during setup?
To assemble PFLD-2W-S120M40A, remove the M40 cable gland and extract the contact. Insert the contact into the insulator and align the cotter pin hole. Strip back the cable jacket by approximately 33mm, then slide the R120 reduction sleeve (brass with silver plating, up to 16.50mm wire diameter) over the exposed conductor. Hammer the cotter pin in from its chamfered side for proper seating. Slide the cable with reduction sleeve into the contact, then tighten both set screws using a 5mm hex key to a minimum of 10.5 N/m. Finally, thread the cable gland back on. The M40 gland includes two rubber bushings (inner diameter 23mm and 33mm) for flexibility with different cable sizes. At 190mm total length with a 32.5mm body diameter, the Line Drain is the longest connector in the PowerFit family, providing ample space for cable management and a secure grip surface.
What advantages does PFLD-2W-S120M40A offer over conventional CAM-type connectors?
PFLD-2W-S120M40A offers several meaningful improvements over conventional single-pole power connectors: the 1000V AC / 1500V DC voltage rating exceeds the typical 600V maximum of traditional alternatives; silver-plated brass contacts deliver lower contact resistance (0.1 milliohms) than plain brass; the integrated M40 cable gland with sealing bushing provides cable strain relief and environmental protection in a single assembly; IP67 protection when mated provides dust-tight and waterproof sealing that most single-pole connectors lack. These features, combined with TUV Rheinland certification and the phase-encoded white housing for L2 identification, make PowerFit a generation ahead of traditional designs.
