These casings are heat resistant plastic and the removable cover has a gasket seal. The casings have precut voids for feed-through fittings. The casings can be equipped with splash resistant fuse holders and circuit breakers.
This structure automatically achieves double isolation since the case is an insulator.
In order to achieve the best electrical safety, we usually manufacture encapsulated transformers with two winding sections. The transformers are CE approved and fulfil European electrical safety regulations.
