Claim:
1. A fuse arrangement, comprising: a first safety fuse having a first contact at a first end of the first safety fuse and a second contact at an opposite second end of the first safety fuse, a second safety fuse arranged adjacent to the first safety fuse and having a first contact at a first end of the second safety fuse and a second contact at an opposite second end of the second safety fuse, the first and second safety fuses being arranged for an electrically parallel connection, wherein each safety fuse comprises a first contact and a second contact, wherein each first contact comprises a blade contact such that the fuse arrangement includes a pair of first blade contacts configured and arranged relative to each other for insertion into a respective pair of blade contact receptacles of a busbar, and a conductive or non-conductive end plate mechanically permanently connected to the first end of the first safety fuse and the first end of the second safety fuse to form a permanent structural unit, such that the first safety fuse cannot be individually removed from the permanent structural unit, whereby the structural unit prevents independent insertion of one of the first blade contacts into one of the blade contact receptacles of the busbar without simultaneous insertion of the other first blade contact into the other blade contact receptacle of the busbar, and prevents independent removal of one of the first blade contacts from one of the blade contact receptacles of the busbar without simultaneous removal of the other first blade contact from the other blade contact receptacle of the busbar, and wherein the respective first contacts of the first and second fuses, and the respective second contacts of the first and second fuses, are electrically connected to a circuit including a current source, and wherein the respective first ends of the first and second safety fuses are mechanically connected to each other by the end plate, and the respective seconds ends of the first and second safety fuses are mechanically disconnected from each other.
