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.
