The electrical circuit breaker (2) includes a circuit breaker block (4) including at least an electrical conductor (43, 49) equipped with a first fixed pastille (44). The circuit breaker block also includes a bridge (46) equipped with at least a second pastille (48), a unit (50) for controlling the mobile bridge and an actuator (52) of the control unit. This actuator is able to switch between an armed configuration in which it activates the control unit and a disarmed configuration in which it does not activate the control unit. The circuit breaker block also includes a first electrical coupling module (58). The electrical circuit breaker also includes a trip block (6) including an electronic trip circuit and a second module (64) for electrically coupling with the first coupling module of the circuit breaker block. This circuit breaker is provided with an actuator arming latch (68).
Description
technical field [0001] The invention relates to an electrical circuit breaker comprising a trip block. Background technique [0002] In the field of electrical circuit breakers, as known practice eg from EPA0843332, two or more independent blocks are provided in the circuit breaker. In this document, an electrical circuit breaker is equipped with a circuit breaker block comprising fixed and mobile lands and a unit for controlling the position of the mobile lands, and with a trip block. It is possible to use circuit breakers with different types of trip unit blocks, eg thermal, magnetic, differential or electronic trip unit blocks. The electronic trip block is able to perform the function of a thermal trip block as well as the function of a magnetic trip block by means of electronic processing of the measurements taken. Such electronic trip unit blocks have a shorter lifespan than circuit breaker blocks. Therefore, it is usually removable and only installed into the circui...
