Excel Mate MSD (Manual Service Disconnect) is a safe and a reliable solution for HEV servicing. Equipped with a two-stage lever to open the HVIL circuit prior to the separation of HV contacts, it is a tool-free solution for disconnecting the internal high voltage battery pack and protecting it from short circuit. All HV conductive contact surfaces on the receptacle assembly are finger touch safe. MSD is available in a scalable design with a variety of fuse ratings and different sizes (standard, Mini and XL). MiniMSD is smaller in size and lower in cost, offering a more compact solution. MSD XL is the biggest version of MSD rated up to 1000V with fuse and 1500V without fuse.
