Abstract

The cover is formed with two cap sections Ä3Ü separated by a gap and produced in an insulating material. The caps are formed on a base plate and have access slots Ä5aÜ at the top. These are sized to provide access for the contact pins of a fuse element with engage the power contacts enclosed by the cover . A centre section has a flap Ä11Ü that provides an access point.
