Heavy Duty Socket & Plug
IEP Marechal Heavy Duty Socket & Plug
Specially designed for heavy-duty industries
Marechal started the DECONTACTOR™ in 1953 with the DN range. As the first industrial plug and socket-outlet equipped with an integral switching device, the DN is still the perfect heavy-duty solution: in its metal version, it offers great resistance to mechanical shock, heat and chemical agents.
In addition, it withstands high overloads conditions. IEP Marechal Electric DN plugs and socket-outlets are designed to last more than 20 years in difficult environments.
