Abstract

The cut-out switch includes a pair of phase limiters within a casing, occupying its full width. A cut-off is positioned in a space between a limiter of one phase circuit and a neutral. A differential part is positioned relative to the other of the circuits. One end of a primary reel is dependent upon a neutral limiter. The other end is linked to a conductor linked to the neutral circuit. Linkage from primary phase reels and neutral to circuits corresponding to one side of a cut-off part between conductors supplying mobile contacts and the corresponding limiters.
