<\/p>\nSelection Guide<\/h2>\n
Choose the DTL-1 model by checking the aluminium conductor against barrel bore d, then match the palm mounting hole \u03a6 and width B to the equipment connection. Compare D, L and L1 with the available installation space. Use a crimping method suitable for the selected conductor and terminal.<\/p>\n
Applications<\/h2>\n
For aluminium-conductor connections to compatible equipment terminals and busbars in power distribution assemblies.<\/p>\n
