A medium voltage controller for electrical equipment, such as motors, transformers, reactors, and capacitors, having a load discharge device. The load discharge device is compact and provides fast earthing of the load-side cables. The device has a scissors-type linkage and is charged by compressing at least one spring. The scissors-linkage, when in an almost-straight-line alignment, holds the compressed springs. An actuator moves one member of the scissors-linkage, thereby removing the holding alignment of the scissors-linkage. The springs move an earthing bar at high acceleration to ground the line-side cables.
