OPTIMA-HD is a range of industrial plugs from 16A to 125A characterized by the use of specific technopolymers that give maximum resistance to impacts (IK10), to heat and fire (GW 960°C according to EN 60695-2-1 ), to atmospheric agents and UV rays The OPTIMA-HD electric plugs are therefore suitable for use in harsh environments such as iron and steel industries, ports and mines. 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. Plugs fast to wire thanks to the opening of the body by means of a Snap-on steel spring mechanism and the screw terminals (16A-32A) or mantle terminals (63A-125A).
