Abstract
This device consists of a housing (1) made of electrically insulating material, in which a fuse (6) is provided with at least one main fuse wire (7) located in its cavity. The main fuse wire (7) is electrically conductively connected at one end to at least one connecting pin (2) which is led out of the housing (1) and at the other end it is electrically conductively connected to at least one terminal (3) located in at least one cavity (4) formed in the housing (1). The shape of the connecting pin (2) is adapted for connection to the protected device.
Claims9
An overcurrent protection device, comprising:
- a housing made of electrically insulating material;
- a fuse provided within the housing, the fuse having at least one main fuse wire located in a cavity of the fuse;
- at least one signal fuse wire connected in parallel to the main fuse wire, wherein
- a first end of the main fuse wire is electrically conductively connected to at least one connecting pin, the connecting pin being led out of the housing and shaped for connection to a protected device;
- and
- a second end of the main fuse wire is electrically conductively connected to at least one terminal located in at least a second cavity formed in the housing;
- an inspection opening provided on the housing;
- a slider disposed under the opening, the slider having a marked display area and being slidably arranged along an inner surface of the housing;
- and
- a lever made of electrically conductive material placed in the housing wherein
- a first end of the lever is electrically conductively anchored to a lead of the terminal, rotatably in a direction perpendicular to the longitudinal axis of the fuse and simultaneously electrically conductively connected to the signal fuse wire;
- and
- a second end of the lever forms a stop for the slider.
