ABSTRACT:
A protective assembly is provided for a power capacitor having three electrical terminals extending outwardly from the top of the capacitor. The protective assembly comprises a mounting plate constructed of an electrical insulating material having three holes formed through it which register with the electrical terminals of the capacitor. The mounting plate is positioned over the capacitor terminals so that the lower side of the mounting plate faces the top of the capacitor while the electrical terminals protrude outwardly from the upper side of the mounting plate. Bleed resistors are connected between each pair of the capacitor terminals on the upper side of the plate. In addition, a fuse assembly is attached to the upper side of the mounting plate and has at least one and preferably three fuse holders. Each capacitor terminal is connected to one of the fuse holders on the fuse assembly while the other terminal for each fuse holder forms the power connection to the electrical load.
