NK Technologies Introduces CT-MS 5A Secondary Current Transformer with Split-Core Design and Larger Aperture for Easy Installation

SAN JOSE, CA – NK Technologies has a new addition to its line of 5A Secondary Current Transformers. The CT-MS has CT-MS 5A Secondary Current Transformera split-core design and larger than average sensing window, making it ideal for installing over large wires or bus bars. The CT-MS measures AC current and produces a 0 – 5 amp output proportional to the current flowing through the sensing window.

The CT-MS 5A Secondary CT offers a compact and cost-effective way of measuring primary current. Key features include:

  • Compatibility with standard power monitors and panel meters designed for 5-amp input
  • Large 2.22” x 1.19” sensing window
  • Measures current from 0 – 150 to 0-800 amps
  • Plated terminals for reliability
  • UR-recognized file E475131
  • Meets ANSI/IEEE C57.13 and IEEE C57.13.2


Founded in 1982, NK Technologies designed the first low-cost solid-state current sensing technology that underlies the industry today.

Today, NK Technologies is a leading provider of current sensing, ground fault detection and power monitoring products to the industrial and factory automation markets, with a product portfolio that includes more than 1300 models to satisfy a wide range of specific application needs.  As the needs of these markets change, NK Technologies is well-positioned to respond with sophisticated new product designs and improved product functionality necessary to meet those applications.
