OPTIMA-TOP is a range surface mounting industrial inlets 63A and 125A. Robust and safe industrial inlets thanks to the use of high performance halogen-free technopolymer enclosures. Practical thanks to the use of mantle terminals, to the reversible base with threaded metric entries on the upper and lower side and to the removable device to ease wiring operations. The efficiency of the contacts over time is guaranteed by the use of nickel-plated brass pins, resistant to oxidation and aging, while the IP degree stability is ensured by the co-moulded gasket.
