Product Details
| Brand Name | Foretech | Place of Origin | China | |
| Model Number | FTB3 | Type | High Voltage | |
| Poles Number | 1 |
Product 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.
