Product Description
The PowerFit 400A Line Drain connector in grey delivers precision European compliance for industrial power distribution networks governed by IEC 60445 and equivalent harmonized standards. This L3 (Line 3) phase connector is engineered to exacting TÜV Rheinland specifications (ID 1111303479), which govern European, Middle Eastern, and Asian markets increasingly adopting IEC-aligned protocols. The female contact, push-and-twist design handles 400 to 660 amperes across dual voltage ratings (1000V AC / 1500V DC maximum) with silver-plated brass contacts that resist tarnish and oxidation in even the most demanding industrial environments. UL94-V0 flame resistance, IP67 mated protection, and full CE compliance ensure risk-free operation in European Union installations, combined heat and power systems, and renewable energy infrastructure where regulatory documentation must trace every component back to certified production records.
Key Features
- Housing Body: Non-conductive, high impact-resistant thermoplastic with integral flame-retardant additives; achieves UL94-V0 rating and resists mechanical shock, UV exposure, and chemical degradation.
- Electrical Conductor (Contacts): Brass substrate with silver electroplating; silver finish prevents tarnish, oxidation, and green patina formation that reduces conductivity over years of service.
- Sealing Ring: Silicone O-ring provides the tight environmental seal required for IP67 protection; maintains elasticity across the full operating range of 45 to 85 degrees Celsius.
- Retention Pin (Cotter Pin): Polyoxymethylene (POM) polymer—high stiffness, low friction, electrical insulation; designed for single use and must be replaced after disconnection to ensure reliable re-mating.
- Cable Coupling Assembly: Nylon and rubber cable gland with M40 × 1.5 metric thread; dual-diameter sealing bushing (22mm and 33mm inner diameter) accommodates standard industrial cables from 19 to 28 millimeter outer diameter.
- Cable Diameter Adaptation Sleeve (R120): Brass body with silver plating; provides mechanical and electrical interface for wires up to 16.50 millimeters diameter without derating the connector's current capacity.

- RoHS & REACH Compliance: No restricted hazardous substances (lead, cadmium, mercury, etc.); all chemical substances registered and notified under REACH regulation, ensuring supplier accountability and end-of-life recycling compliance.
- UL94-V0 Flame Rating: Housing material meets the strictest vertical flame propagation standard; critical for enclosed cabinets, explosive atmospheres, and applications where fire spread could cascade into facility-wide disasters.
- Silver-Plated Brass Contacts: Superior surface finish resists corrosion and oxidation; maintains contact resistance at 0.1 milliohms even in high-humidity industrial sites, salt-spray coastal installations, and chemically aggressive manufacturing floors.
- TÜV Rheinland: Certified under product ID 1111303479 (includes Type Approval, Safety Testing, and Regular Production Surveillance)
- CE Marking: Full compliance with European Union Directives 2014/34/EU (ATEX), 2014/35/EU (LVD), and other applicable technical harmonization directives
- RoHS Directive 2011/65/EU: All restricted substances (lead, cadmium, hexavalent chromium, etc.) eliminated or below threshold levels
- REACH Regulation EC 1907/2006: All chemical substances registered and safety data sheets available; full supply-chain accountability
- IEC 60445: Aligned with European and international color-coding standards for AC power systems; grey designation for L3 phase
- UL94-V0 Material Rating: Housing passes vertical flame test; flame does not spread and no burning drips ignite cotton placed beneath specimen
Applications
- Complete three-phase power distribution requiring all three phase inline connectors
- Large-scale touring production feeder cable systems for arenas and stadiums
- Industrial automation and motor drive power distribution cabling
- Welding power supply connections and high-current process equipment
- Marine and shipboard temporary power connections with environmental sealing
- Portable substation feeder cables for utility and emergency power deployment

Compatibility
The PowerFit 400A Line Drain connector is compatible with major brands of single-pole power connector systems. Its push-and-twist mating mechanism ensures standardized connection geometry across certified suppliers. The female contact mates with PowerFit Line Source and Panel Source connectors. Verify mechanical and electrical specifications with your mating connector manufacturer to confirm impedance matching and 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
PFLD-3GY-S120M40A FAQ
What is the PFLD-3GY-S120M40A and what role does it play in a PowerFit system?
PFLD-3GY-S120M40A is a KUPO PowerFit 400A line drain connector with a grey housing, identifying Line 3 (L3) under Europe and UK (IEC 60446) 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 grey housing enables instant visual identification of the L3 conductor across cable runs. It is commonly deployed in theme park and entertainment venue applications. Permanent outdoor entertainment installations demand connectors that survive years of sun exposure, seasonal weather changes, and constant operation.
What voltage and amperage is PFLD-3GY-S120M40A rated for?
PFLD-3GY-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 grey housing on PFLD-3GY-S120M40A represent under Europe and UK (IEC 60446) standards?
Grey identifies Line 3 (L3) under IEC 60446, completing the European three-phase color set of brown (L1), black (L2), grey (L3). Grey L3 is standard across all EU member states, the UK (post-2004), and countries that have adopted IEC harmonized wiring colors. On the Line Drain connector, the grey housing is visible along the full 190mm body length, making L3 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. In large-scale European venue installations, grey L3 connectors provide visual confirmation that all three phases of the IEC set are present and correctly assigned.
What safety standards govern the design and manufacture of PFLD-3GY-S120M40A?
PFLD-3GY-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-3GY-S120M40A versatile for theme park and entertainment venue applications?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The flame-retardant thermoplastic housing resists UV degradation, TUV Rheinland certification meets European safety requirements for permanent installations, and the 500-cycle mating life supports seasonal maintenance schedules. For L3 circuits using Europe and UK (IEC 60446) color conventions, the grey PFLD-3GY-S120M40A ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
