Model and Meaning

Product Features
● Increase the heat transfer efficiency, significantly reducing the additional temperature rise caused by the temperature rise of the adapter on connectors, cable terminations, and partition plates.
● The separation between functional units and isolation zones is clear and reliable, ensuring that a failure in one unit does not affect the operation of other units, thereby limiting faults to the smallest possible scope.
●The busbar’s horizontal arrangement ensures excellent dynamic and thermal stability of the device, enabling it to withstand the impact of a short-circuit current of 80/176 kA.
