Abstract: A multi-pole switch comprising a bottom portion (10) and a top portion (20) divided into a plurality of switch sections, i.e. one switch section per pole, whereby each switch section comprises a set of fixed and a set of movable contacts, and a section for mechanical actuation which causes a displacement of a bar member extending through all the sections and to which the movable contacts are secured. A tripping module (50) can be included in an opening (12) at the top of the section for mechanical actuation, said tripping module comprising a spring for storing of mechanical energy and means actuating an actuating means fixedly connected to the bar member. As a result, the energy stored in the spring can be substantially converted into a displacement of the bar member when the tripping module (50) is released by a signal from an excess current relay (60). The mechanical actuation is preferably included in a corresponding module (40) which is mounted in the switch through a corresponding opening (12) in the bottom of the section.
