Product Description
The PFLS-2BK-S120M40A brings industrial-grade power distribution to European and IEC-standard installations. As a Line Source connector with male contact and key-release pin, this inline solution enables seamless mating to Drain connectors while supporting 400A continuous current. The black phase conductor aligns with IEC conventions for L2 applications across industrial facilities, temporary power systems, and event staging where reliable European power standards are required.
Key Features
- Male Contact with Key-Release Pin: Innovative push-and-twist design with tool-free disconnection via key-release mechanism for user safety and rapid reconnection workflows.
- Push-and-Twist Connection: Intuitive mating procedure - no CAM tools or complex alignment steps required in high-pressure event environments.
- Compact POM Cotter Pin: Shorter polyoxymethylene pin optimizes connector footprint while maintaining reliable locking; removable with small slotted screwdriver if field adjustment is needed.
- 400A Continuous Capacity: Rated for 400A with 120mm² cable.
- IP67 Sealed Mating: Protects against dust, water spray, and temporary submersion when connectors are fully mated and locked.
- M40 Cable Gland with Dual Bushings: Nylon and rubber sealing system with 22mm and 33mm ID options ensures strain relief across cable diameter ranges.
- Not for current interruption: connect and disconnect only when the circuit is de-energized
Certifications & Standards
- TÜV Rheinland: Certified (ID 1111322264), covering type approval, safety and regular production surveillance
- CE Marked
- RoHS & REACH: Fully compliant
Applications
The PFLS-2BK-S120M40A excels in European and IEC-compliant installations:
- Industrial facilities with three-phase power distribution
- Temporary power systems for construction, theater, and event production
- Data centers and critical infrastructure requiring 400A L2 branch circuits
- Broadcasting and live entertainment setups where rapid power deployment is essential
- Renewable energy installations (solar farms, wind systems) with European grid compliance
Compatibility
The PFLS-2BK-S120M40A (Source) mates directly with PFLD-2BK-S120M40A (Line Drain) and PFPD-2BK (Panel Drain) connectors, completing power chains from source through distribution to branch circuits. This connector is compatible with major brands of single-pole power connector systems. Ensure matching phase conductors (L2 Black/IEC) throughout the circuit to prevent cross-phasing.

Frequently Asked Questions
Why was PFLS-2BK-S120M40A designed with a key-release mechanism?
PFLS-2BK-S120M40A is a KUPO PowerFit 400A line source connector with a black housing, identifying Line 2 (L2) under Europe and UK (IEC 60445) 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 electrical performance does PFLS-2BK-S120M40A deliver?
PFLS-2BK-S120M40A is rated for 400 amperes continuous with 120mm² cable. The maximum voltage rating is 1000V AC or 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.
Why choose the black L2 variant (PFLS-2BK-S120M40A) for your installation?
Under IEC 60445, black identifies Line 2 (L2). This is the second phase conductor in the European three-phase system of brown (L1), black (L2), gray (L3). For international crews, this is a critical distinction: the same black housing that means L1 in North America means L2 in Europe. On the Line Source connector, the black 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. Cross-convention errors between NEC-L1-black and IEC-L2-black are among the most common phase identification mistakes on international projects.
What safety certifications apply to PFLS-2BK-S120M40A?
PFLS-2BK-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.
Is PFLS-2BK-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 400A continuous rating handles industrial loads, the flame-retardant UL94-V0 housing resists chemical exposure, and the push-and-twist lock prevents vibration-induced disconnection. For L2 circuits using Europe and UK (IEC 60445) color conventions, the black PFLS-2BK-S120M40A ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
