Abstract
A device and a system for preventing insertion of a fuse into a fuse holder, and methods for using the same. The device and the system comprise retaining elements that are adapted to engage with a fuse holder. When the device or system is engaged in a fuse holder, it is not possible to insert a fuse into the fuse holder. This allows for safe isolation of electric circuits.
Claims21
A fuse insertion prevention device for preventing insertion of a fuse into a fuse holder, the device comprising:
- a plurality of retaining elements configured to engage with a fuse holder, and
- a resilient member situated between the plurality retaining elements,
- wherein:
- the retaining elements are moveable relative to each other between an engaged and a released position, such that:
- in the engaged position the resilient member exerts pressure on the plurality of retaining elements thereby urging them apart, and
- in the released position the retaining elements are moved towards each other and the resilient member is compressed.
