ABSTRACT:
An insulation plate (20) is provided with a window or a slot (21). A fusible element or circuit (31) with reinforced portion (22) is laid on a surface of the insulation plate (20) across the window (21). When the circuit (31) is heated by current-conduction, a fusible path (33) of the circuit (31) spanned in air across the window (21) melts at a predetermined current level, since heat generated in the fusible path (31) is not absorbed in the insulation plate (20). It is possible to transform the plate fuse depending on the conditions of use, and its configuration is substantially flexible.
