Abstract
A resistor apparatus for containing broken pieces of an overheated resistor body is provided. The resistor apparatus includes a resistor body and a first and second lead wire electrically connected to opposite sides of the core. A gas permeable containment casing substantially encloses the resistor body and is fixed to the lead wires by fasteners, therefore maintaining the containment casing in a position substantially enclosing the resistor body. In the event that the resistor overheats and the resistor body breaks, the containment casing is maintained in a position to contain any pieces of the overheated resistor that break away, while allowing any gasses to escape, therefore preventing explosion of the containment casing and damage to surrounding apparatuses.
