Stud Terminals

Elmex Controls offers a wide range of Stud Type Terminals, both in Melamine and Polyamide 6.6 housings, from conductor size of 0.5 sq.mm to 35 sq.mm. In these terminal blocks, conductors prepared using ring/fork type lugs are terminated by means of hex nuts or long round nuts, depending on the type of terminal. For making connections, these nuts have to be opened up and removed from the bolt before inserting the lug, which is then tightened up using a screwdriver or nut driver. Further, these terminals can be provided with separate protective covers as a safety measure. As an innovative solution, the company has developed two more types of stud terminals, OAT2.5 and OAT6, suitable for rated conductor size 2.5 sq.mm and 6 sq.mm respectively. These terminals are provided with hinged covers within which the nuts remain captive. When the covers are opened up, carrying the captive nuts, the threaded bolts of the terminals are ready to receive the conductor prepared using ring/fork type lugs crimped with the conductor. When the covers are closed, the captive nut positions itself on the threaded bolt. The nuts are then tightened with a screwdriver, to establish connections. The covers fully shroud the liver metal parts and the insulated lug in the conductor clamping area, ensuring safety against electric shock hazard. Since the nuts are captive in the hinged covers, (i.e., no need to open them up), this type of construction facilitates quick and convenient way of making connections.
