400A single-pole line source connector. Key-release pin, IP67, silver-plated brass contacts, TÜV certified.
TÜV Rheinland certified (ID 1111303479): Type Approved, Safety, Regular Production Surveillance. CE marked. RoHS and REACH compliant. Flame Class UL94-V0. IP67 rated while mated. Working temperature: 45°C to 85°C. Mating cycle: 500.
Compatible with major brands of single-pole power connector systems. The push-and-twist mating mechanism with key release pin ensures reliable connection geometry and convenient tool-free disconnection across standardized suppliers, enabling integration into existing power distribution infrastructure.
Best suited for:
Mobile power distribution for touring productions and live events, industrial plant power management, generator and UPS distribution panels, renewable energy systems, heavy machinery power supply, and wet or dust-prone environments where IP67 sealing prevents system failures.
Purpose-built for North American power systems, the PFLS-2R-S120M40A delivers 400A L2 connectivity with the reliability expected in demanding event and entertainment applications. This Line Source connector features a male contact and patent key-release pin for intuitive push-and-twist mating, eliminating the need for complex tools or procedures during rapid deployment scenarios. Red phase identification follows NEC convention, making it the trusted choice for large-venue events, touring productions, and high-amperage temporary power installations where speed and safety cannot be compromised.
The PFLS-2R-S120M40A (Line Source, male contact) mates directly with PFLD-2R-S120M40A (Line Drain, female contact) and PFPD-2R (Panel Drain) connectors to form complete power distribution chains. This connector is compatible with major brands of single-pole power connector systems. Always match phase colors throughout the circuit (red L2 to red L2) to prevent cross-phasing and ensure electrical code compliance.

PFLS-2R-S120M40A is a KUPO PowerFit 400A line source connector with a red housing, identifying Line 2 (L2) under North America (NEC) conventions. As the source side of an inline cable connection, it features the innovative patent key-release pin that enables tool-free disconnection. The push-and-twist mechanism secures the connection during operation while allowing rapid uncoupling when needed. It is commonly deployed in construction site applications. Construction power distribution deals with dust, debris, rain, rough handling by crews, and the constant repositioning of equipment as the site evolves.
PFLS-2R-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 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.
Red marks Line 2 (L2) under North American NEC conventions. In a standard three-phase system, the color sequence is black (L1), red (L2), blue (L3). Red L2 is one of the most commonly ordered phase variants for US and Canadian power distribution, appearing in virtually every multi-phase temporary power installation. On the Line Source connector, the red housing wraps the 170mm body including the area around the key-release mechanism. This means the phase is identifiable even during the push-and-twist connection process, reducing the chance of connecting to the wrong L2 circuit. Red is one of the most visually distinctive colors on a busy event site, helping crews quickly trace the second phase conductor even from a distance.
PFLS-2R-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 key-release pin mechanism has been certified as part of the TUV evaluation, ensuring that the disconnect feature meets the same safety standards as the connection itself.
The PFLS-2R-S120M40A features the innovative PowerFit push-and-twist connection. To connect, align the connector and push while twisting until it locks. To disconnect, the patent key-release pin enables tool-free uncoupling. Simply press the release and twist to separate. If needed, a small slotted screwdriver can assist with the release. For cable termination, the process follows the same steps as other PowerFit line connectors: strip 33mm of cable jacket, apply the reduction sleeve, tighten set screws to 10.5 N/m minimum, and secure the M40 cable gland. Uses the shorter cotter pin variant (vs the longer pin in Line Drain). The shorter pin accommodates the key-release mechanism. Never reuse cotter pins.
PFLS-2R-S120M40A offers several meaningful improvements over conventional single-pole power connectors: the integrated M40 cable gland with sealing bushing provides cable strain relief and environmental protection in a single assembly; the patent key-release pin enables tool-free disconnection that traditional locking mechanisms cannot match; 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 red housing for L2 identification, make PowerFit a generation ahead of traditional designs.
