A high-capacity miniature cartridge fuse is provided. A fuse includes a cylindrical housing, a fusible wire, and first and second deep-drawn ferrules fabricated from aluminum alloy. The aluminum is plated with nickel. The ferrule includes a side wall and an end wall. The side wall surrounds the first or second end of the housing, and has a thickness of approximately 0.50 mm or less. The end wall includes a boss extending toward an interior of the housing, and has a thickness greater than the thickness of the side wall.

The invention relates to a melting conductor (1) provided for use for a fuse (2), preferably for a miniature fuse, with an electrically conductive melting wire (3). According to the invention an electrically insulating and/or electrically non-conductive covering (5) surrounding the outer shell surface (4) of the melting wire (3) at least in certain areas, preferably completely, is provided.

Systems, methods, and apparatus to facilitate wireless device monitoring and control are provided. A first device controller may be adapted to be disposed within a power connector, in series with conductors of the power connector. The power connector may be adapted to provide power from a power source to a device. The first device controller may include two terminals to electrically couple the first device controller with the conductors of the power connector. The first device controller may further include a power component to power the first device controller. The first device controller may be configured to monitor one or more conditions of the device, control one or more functions of the device, and wirelessly communicate with a system controller that is remote from the power connector and the device. The power connector may correspond to a power plug and/or a terminal block.
