Abstract

A magnetothermal circuit breaker comprising a casing (103) which contains an electrical protection device (110) associated with a magnetic trip-off kinematic system (114), a kinematic system for actuating the moving contact (111), an arc chute (112), a thermal trip-off kinematic system (113), a connection means (115) for the external electrical connections; the thermal trip-off kinematic system includes a bimetallic member which is operatively associated with a linkage whose initial position with respect to the bimetallic member can be adjusted mechanically.
