Product Description
Purpose-built for North American power systems, the PFLS-2O-S120M40A delivers 400A L2 connectivity with the reliability expected in demanding event and entertainment applications. This Line Source connector features a male contact and key-release pin for intuitive push-and-twist mating, eliminating the need for complex tools or procedures during rapid deployment scenarios. Orange phase identification follows the common USA 277/480V 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.
Key Features
- Male Contact with Key-Release Pin: Effortless tool-free disconnection via proprietary key-release mechanism - designed for busy event technicians who need quick reconfiguration without equipment damage risk.
- Push-and-Twist Mating: No alignment tools, no CAM locks - simply push fully and twist to secure. Disconnect by engaging the key-release pin and pulling apart.
- Compact POM Cotter Pin: Engineered shorter than Drain variants for optimal inline connector profile; field-serviceable with a small slotted screwdriver if needed.
- 400A Continuous Rating: Tested for sustained 400A with 120mm² cable.
- IP67 Sealed When Mated: Full environmental protection during operation in outdoor events, rain, or moisture-prone venues.
- Nylon/Rubber Cable Gland: M40 x 1.5 cable gland with nylon and rubber sealing provides strain relief for cable Ø14 to 33 mm (insert CG-M4015-32) or Ø12 to 18 mm (insert CG-M4015).
- Not for current interruption: connect and disconnect only when the circuit is de-energized
Certifications & Standards
- TÜV Rheinland Certification: ID 1111322264 (type approval, safety and production surveillance)
- CE Declaration: European market authorization
- RoHS & REACH Compliance: Fully certified for hazardous substance restrictions
Compatibility
The PFLS-2O-S120M40A (Line Source, male contact) mates directly with PFLD-2O-S120M40A (Line Drain, female contact) and PFPD-2O (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 (orange L2 to orange L2) to prevent cross-phasing.
Applications
- Three-phase power source connections requiring dedicated L2 feed lines
- Entertainment dimmer rack and lighting control source power feeds
- Industrial manufacturing source power connections with three-phase requirements
- Power distribution source connections for mining and heavy industry operations
- Festival and outdoor event source power feeds with weather-exposed installations
- Generator paralleling output connections requiring per-phase source management
- UPS and bypass panel source power cabling for critical infrastructure

Frequently Asked Questions
What is PFLS-2O-S120M40A and what makes it innovative?
PFLS-2O-S120M40A is a KUPO PowerFit 400A line source connector with an orange housing, identifying Line 2 (L2) under USA 277/480V conventions. As the source side of an inline cable connection, it features the innovative key-release pin that enables tool-free disconnection. The push-and-twist mechanism secures the connection during operation while allowing rapid uncoupling when needed.
What are the current and voltage specifications for PFLS-2O-S120M40A?
PFLS-2O-S120M40A is rated for 400 amperes continuous with 120mm² cable. The maximum voltage rating is 1000V AC or DC. The insulation resistance exceeds 5000 megaohms at 500V AC, and the test voltage rating of 4500V AC provides substantial safety margin. Its short-time withstand rating is 16 kA for 1 second.
Why choose the orange L2 variant (PFLS-2O-S120M40A) for your installation?
Orange marks Line 2 (L2) in the brown, orange, yellow phase sequence that is common practice for USA 277/480V systems. In that convention the sequence is brown (L1), orange (L2), yellow (L3), with a gray neutral; it is widely used, but the NEC does not mandate phase colors, so always confirm against the project wiring drawing. Orange L2 belongs to the brown, orange, yellow set used for 277/480V power distribution in the United States, including large temporary power installations. On the Line Source connector, the orange 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. Orange 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.
Is PFLS-2O-S120M40A independently tested and certified?
PFLS-2O-S120M40A is TÜV Rheinland certified to IEC 61984 (ID 1111322264) under Type Approval, Safety, and Regular Production Surveillance categories. It also holds CB and UKCA certificates, and carries CE marking, RoHS compliance (Restriction of Hazardous Substances), and REACH compliance. The housing material achieves a UL94-V0 flammability rating, which is the top rating in the UL94 vertical burn (V) series, meaning the material self-extinguishes within 10 seconds with no flaming drips. The key-release pin mechanism has been certified as part of the TÜV evaluation, ensuring that the disconnect feature meets the same safety standards as the connection itself.
What is the assembly and disconnection process for PFLS-2O-S120M40A?
The PFLS-2O-S120M40A features the innovative PowerFit push-and-twist connection. To connect, align the connector and push while twisting until it locks. To disconnect, the 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.
How does PFLS-2O-S120M40A compare to traditional single-pole power connectors?
PFLS-2O-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 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 TÜV Rheinland certification and the phase-encoded orange housing for L2 identification, make PowerFit a generation ahead of traditional designs.
