Product Description
The PowerFit 400A Line Drain connector in yellow delivers rugged, reliable performance in harsh outdoor and industrial environments. Built to IP67 specifications and UL94-V0 flame-resistant standards, this push-and-twist female contact connector handles up to 400 amperes continuously while maintaining full ingress protection even in wet, dusty, and corrosive conditions. Yellow coding identifies this connector as Line 2 phase under the UK older BS 7671 convention, ensuring correct phase recognition in legacy UK installations and mixed-standard multi-region deployments. The non-conductive thermoplastic housing with high impact resistance protects against mechanical shock and chemical exposure, while the silver-plated brass contacts guarantee stable long-term conductivity under demanding environments.
Key Features
- IP67 Sealed: Complete environmental protection when mated—water, dust, and debris cannot compromise the electrical connection even in continuous outdoor use.
- UL94-V0 Flame Resistance: Housing material meets the strictest flammability standard, essential for safety-critical installations and regulatory compliance.
- Push-and-Twist Connection: Intuitive connection mechanism with secure mating; the patent key-release pin on source connectors enables single-handed disconnection without tools.
- Silver-Plated Brass Contacts: Superior corrosion resistance compared to plain brass; maintains contact resistance at 0.1 milliohms even under salt spray, humidity, and thermal cycling.
- High Impact-Resistant Thermoplastic: Non-conductive housing absorbs mechanical shock while resisting UV degradation, chemical attack, and extreme temperature fluctuation.
- Nylon & Rubber Cable Gland: Ergonomic M40 × 1.5 gland with dual-size bushing (22mm and 33mm inner diameter) secures cables from 19–28mm diameter; rubber grip ensures safe handling in wet gloves.

Frequently Asked Questions
PFLD-2Y-S120M40A FAQ
Who needs PFLD-2Y-S120M40A and what problem does it solve?
PFLD-2Y-S120M40A is a KUPO PowerFit 400A line drain connector with a yellow housing, identifying Line 2 (L2) under UK (Old, pre-2004) 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 yellow housing enables instant visual identification of the L2 conductor across cable runs. 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 ratings and wire capacity of PFLD-2Y-S120M40A?
PFLD-2Y-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 L2 circuits carrying continuous phase current.
What does the yellow housing on PFLD-2Y-S120M40A represent under UK (Old, pre-2004) standards?
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 Line Drain connector, the yellow 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. When maintaining or extending pre-2004 UK installations, matching the existing yellow L2 convention prevents confusion between old and new color systems.
What certifications and safety ratings does PFLD-2Y-S120M40A carry?
PFLD-2Y-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-2Y-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 0.1 milliohm contact resistance minimizes heat generation at connection points, the 500-cycle mating rating supports repeated connect/disconnect during maintenance, and the 1000V AC / 1500V DC rating provides margin for high-voltage DC distribution architectures. For L2 circuits using UK (Old, pre-2004) color conventions, the yellow PFLD-2Y-S120M40A ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
How do you assemble PFLD-2Y-S120M40A onto a power cable in the field?
To assemble PFLD-2Y-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.
