Abstract
A modular electrical switch device including: a cut-off unit including unitary cut-off units; an actuating unit of the unitary cut-off units including an electromagnetic actuator including a fixed cylinder head and a movable reinforcement; a mechanism allowing the actuating unit to be fixed to the cut-off unit; a quick attachment mechanism allowing removable fixing of the actuating unit on the cut-off unit, and including at least one coupling hook configured to fix and hold the cut-off unit to the actuating unit, and to engage with an actuating device of the unitary cut-off unit to transmit movement of the actuator.
Claims15
A modular electrical switching device comprising:
- a switching block comprising unitary switching blocks respectively comprising at least one fixed contact that can collaborate with a mobile contact;
- an actuation block of the unitary switching blocks comprising an electromagnetic actuator comprising a fixed yoke and a mobile keeper configured to be displaced with respect to the fixed yoke between an open position and a closed position of the electrical contacts;
- means allowing the actuation block to be fixed onto the switching block;
- rapid fixing means allowing a removable fixing of the actuation block onto the switching block, the rapid fixing means comprising at least one coupling hook configured:
- to fix and secure the switching block to the actuation block, and
- to collaborate with an actuation device of the mobile contact of a unitary switching block to transmit movement of the electromagnetic actuator to the mobile contact,
- the coupling hook being secured to the mobile keeper of the electromagnetic actuator.
