Primary current from 50A to 4800A

For bus bars 20,25,30,40,50,60,80 or 100 mm wide

For cable diameter up to Ø 60 mm

Terminal cover as standard for enhanced safety

 

Moulded case current transformers for the measurement of AC currents from 50A to 4800A.

They are made of a non-flammable plastic material. This new range of current transformers has been designed for an easy installation: all transformers can be delivered with DIN rail clips. They are equipped as standard with a sealable terminal cover to comply with the most demanding safety requirements. This range include current transformers for measuring duties and is suitable for every simple application.
