Abstract (en)
[origin: EP0611224A1] Differential protection unit which can be associated with a multi-pole circuit breaker in order together to constitute a differential circuit breaker. This unit comprising: a housing consisting of a lower half-housing (14A) and an upper half-housing (14B) capable together of enclosing various active elements of the differential protection unit, these various active elements constituting at least: a set of connections (22); a torus with a coil; and a circuit-breaking control mechanism (34). According to the invention, a chassis is provided on which the said active elements (22, 34) are fixed, together forming a rigid functional subassembly (16); it results therefrom that the said functional subassembly (16) can be connected to the differential circuit breaker so as to be able to carry out a functional test of the functional subassembly (16) while being able to have access to at least some of the said active elements (22, 34). <IMAGE>
