Product Introduction

Product Features

  1. The product components adopt a modular design, equipped with simple and reliable "five-prevention" interlocking.
  2. Utilizes high-quality epoxy resin material for solid-sealed arc extinguishing chamber circuit design, with a single solid-sealed pole partial discharge ≤5PC (45kV), enhancing the circuit breaker's adaptability and reliability in harsh environments, and enabling maintenance-free operation throughout its lifecycle.
  3. Integrated design of isolating switch, circuit breaker switch, and grounding switch, featuring a clear isolation break.
  4. The panel employs a primary simulation line identification design, which is simple and easy to understand, preventing misoperation.
  5. Current transformers can be installed on the switch's outgoing side, allowing for reduced cabinet or box transformer dimensions.
  6. Can be equipped with an intelligent online monitoring unit and diagnostic system, enabling remote acquisition of the switch's operating status through a communication module.
