The WTR 4 is offered as the industry's first disconnect test terminal with a built-in cross-connection. Used with a plug-in SIHA fuse holder, the terminal can be quickly converted into a fuse terminal, providing two functions in one. The terminals feature a tin-bronze disconnect blade and the tin-leaded protective coating provides low contact resistance and corrosion protection. The compact design of the terminal, with a width of 6 mm, enables users to increase the density of their terminal installations. The blocks feature insulating material that has a temperature limit of 120°C, allowing the new terminals to be used in harsh environments. An optional SIHA fuse housing is available to convert a disconnect into a fuse terminal. The terminals are priced from $3.60 to $8.79.
