Designed for installations using older IEE wiring conventions where yellow designates L2 phase, this Line Source connector delivers 400A continuous capacity with the innovation of a patent key-release pin and push-and-twist mating interface. Yellow phase identification ensures compatibility with heritage installations, touring equipment pre-wired to IEE standards, and mixed-vintage systems where gradual migration to current standards is underway.

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.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n    \u003ch3\u003eWhy choose the yellow L2 variant (PFLS-2Y-S120M40A) for your installation?\u003c\/h3\u003e\n    \u003cp\u003eYellow identifies L2 under the legacy UK wiring color code (red\/yellow\/blue for L1\/L2\/L3) used before the 2004 harmonization to IEC standards.

On the Line Source connector, the yellow 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.

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.
