Features

The product's three main strengths are as follows:

  1. The absence of moving contacts contributes to its long life and high-speed, high-frequency opening and closing capabilities.
  2. Zero-cross control suppresses noise generation and inrush current.
  3. Optional, customizable control circuits and thyristor drive circuits can be installed.

 

Extensive lineup

Our product line is extensive, offering more than 60 varieties, ranging from low current types of 30A to high current types of 2800A.
