High-Current, Universal-Clamp Terminal Blocks

Molex's DIN-rail or panel-mountable high-current universal-clamp terminal blocks offer a versatile solution for high-current and voltage applications requiring aluminum-to-aluminum, copper-to-copper, or aluminum-to-copper terminations. The industry is moving to smaller and smaller electrical components. These terminal blocks offer approximately 1/3 space savings compared to similar product from competitors. Dissimilar conductor materials need to be connected. Aluminum and copper wires do not co-exist very well due to the potential for oxidation and resulting high contact resistance. Molex high-current universal-clamp terminal blocks are designed to safely connect aluminum and copper wires due to their isolated, tin-plated aluminum contacts and hex screws. They are suitable for -40°C to +105°C operating temperatures. High-voltage, high-current applications require resistance to short circuiting to circumvent increasingly dangerous situations. Molex high-current universal-clamp terminal blocks have been short circuit tested according to the stringent requirements of IEC standard EN 61238-1:2003. This is particularly critical when aluminum wire is used in power feed line applications. These terminal blocks are rated to output 1000 V for applications such as railway systems, photovoltaic (solar), and ships. For less-demanding applications, a 600 V option is available. Currents range from 150.0 A to 380.0 A.
