Quick Information

  • Brand Name: Foretech
  • Place of Origin: China

Description

A breaking capacity of 12kA up to 32A and 10kA between 40 to 63A.
Current-limiting scheme: in the event of a short circuit, are able to limit the let-through current to 60%-70% of the rated current. The trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime.
