Product Description
Built for mobile touring operations across the Southern Hemisphere and legacy UK installations, the PFLS-1R-S120M40A streamlines field setup with a breakthrough: the integrated key-release pin that eliminates fumbling with tools when reconfiguring power lines. Australia and UK-Old phase-standard red marking ensures crew recognition across regional venues and hire houses. This 400A/660A dual-rated Line Source connector pairs a male contact with push-and-twist connection geometry optimized for high-frequency connect/disconnect cycles typical of touring shows. Brass silver-plated conductivity and IP67 environmental sealing mean reliable performance from Queensland outdoor festivals to UK arena circuits.
Key Features

Frequently Asked Questions
PFLS-1R-S120M40A FAQ
How does PFLS-1R-S120M40A improve on traditional single-pole power connectors?
PFLS-1R-S120M40A is a KUPO PowerFit 400A line source connector with a red housing, identifying Line 1 (L1) under Australia 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 film location shoot applications. On-location film production often runs power through variable terrain and weather conditions that studio stages never face.
What are the current and voltage specifications for PFLS-1R-S120M40A?
PFLS-1R-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.
Why choose the red L1 variant (PFLS-1R-S120M40A) for your installation?
Australian wiring standards designate red as the Line 1 (L1) conductor. The Australian three-phase color set is red (L1), white (L2), and blue (L3). Red L1 is also used in parts of New Zealand and some Asia-Pacific regions that follow Australian electrical practices. 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 L1 circuit. Using the correct L1 color prevents phase rotation errors that can damage three-phase motors and sensitive equipment.
Is PFLS-1R-S120M40A independently tested and certified?
PFLS-1R-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.
Can PFLS-1R-S120M40A be integrated into an existing power distribution system?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The IP67 rating means production does not stop for rain, and the push-and-twist connection resists accidental disconnection from cable tension or foot traffic across cable runs. For L1 circuits using Australia color conventions, the red PFLS-1R-S120M40A ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
What is the assembly and disconnection process for PFLS-1R-S120M40A?
The PFLS-1R-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.
