Wiha 45796 is a 250 mm hand-crimp tool dedicated to MC4-type photovoltaic connectors. Its dies are profiled for the tinned copper contacts used in standard MC4 male and female housings across the common 2.5, 4 and 6 mm² PV cable ranges. Typical use is on-site assembly of DC string cabling between solar modules, combiner boxes and inverters.
