ABSTRACT:
An overcurrent protection module includes a base unit and a removable fuse holder. The base unit is mountable on a panel or a DIN rail so that a containing space for the fuse holder stands perpendicular to a plane of the panel or the DIN rail, and in line with a conventional wiring orientation. The fuse holder includes at least three fuse slots arranged in a single plane, so that in a position inserted in the base unit, the fuse slots are perpendicular to the plane of the panel or DIN rail. Line terminals are singularly located on a first side wall of the base unit and load terminals are singularly located on a second side wall, opposite to the first side wall. The overcurrent protection module according to the invention is simpler to mount and requires less surface mounting space than a conventional fuse block. The overcurrent protection module also provides protection from shock hazard by shielding an operator from contact with live terminals or fuses.
