Overview

Mencom Corporation’s KTNLS-03IV12 is a 3-pole rectangular connector kit designed for heavy-duty industrial applications requiring reliable, high-performance connectivity. This kit includes a metal enclosure (size 21.21) with a single latch mechanism, a female insert, a male insert, and a hood featuring a top 1/2" NPT cable entry. The screw terminal inserts support wire gauges from 26 to 14 AWG, ensuring compatibility with a wide range of industrial wiring standards. The stainless steel locking system provides consistent clamping force and maintains IP65 protection even after 500 mating cycles, making it ideal for harsh environments where durability and reliability are critical. The metal enclosure meets NEMA 4/4X/12 standards, offering robust protection against dust, water, and corrosion. The KTNLS-03IV12 is part of Mencom’s globally recognized ILME series, a leader in the industrial connector industry, and is manufactured in Germany. This connector kit is suitable for applications in automation, control panels, machinery, and other industrial settings where secure, long-lasting electrical connections are essential. The top entry design simplifies cable routing, while the single latch ensures quick and secure mating. The kit is sold separately from the cable gland, allowing for flexible installation options. For additional thread options (PG or Metric), refer to Mencom’s NPT thread options guide.
