Sobre uma das faces laterais estreitas da caixa 10, existe um par de terminais 16, 18 de alimentação do aparelho alojado na caixa 10, tendo a face oposta de saída um par de terminais 20, 22. Os terminais opostos 16, 20 pertencem a um circuito de fase instalado no interior da caixa 10, ao passo que os terminais 18, 22 pertencem a um circuito de neutro justaposto ao circuito de fase. Uma divisória intermédia isolante 24 é intercalada entre as duas conchas 12, 14, estendendo-se paralelamente as duas faces laterais grandes da caixa 10.In the Figures, a molded box 10 in a general parallelepiped form corresponding to the modular system commercially called MULTI 9, consists of the assembly of two half shells 12, 14. On one of the narrow side faces of box 10, there is a pair of terminals 16, 18 power supply of the device housed in box 10, with the opposite outlet face a pair of terminals 20, 22. Opposite terminals 16, 20 belong to a phase circuit installed inside box 10, while terminals 18, 22 belong to a neutral circuit juxtaposed to the phase circuit. An insulating intermediate partition 24 is inserted between the two shells 12, 14, extending in parallel the two large side faces of the box 10.

The fixed contact 26 is extended by an arc part32 which extends into the interior of an arc extinction chamber in front of an arc part 34 placed at the rear of the movable contact 28. The arc part 34 is connected by a braid 36 to the movable contact 28 and extends through a connecting conductor 38, which passes transversely from the housing to an adjacent part containing the differential part of the circuit breaker described below. A second connecting conductor 40, parallel to conductor 38, extends to output terminal 22. The phase circuit, analogous to said neutral circuit, contains an input terminal 16 with a fixed contact 42 which cooperates with a moving contact 44 of the contact insulating arm 30. The fixed contact 42 extends through an arc piece 46, arranged in front of the arc piece 48 connected to the output terminal 20.

Only the phase circuit contains triggers. The differential part 64 of the box 10, adjacent to the neutral circuit, contains the elements that ensure the differential protection, in the event of the triggering of the mechanism 60 when there is a ground fault.

A parte diferencial 64 contém um transformador diferencial com núcleo toroidal 66 com os enrolamentos primários de neutro 68 e de fase 70 ligados respectivamente aos condutores de ligação 38, 40 e 54, 56. 0 transformador diferencial 66 tem um enrolamento secundário 72 que alimenta um relé polarizado 74. 0 relé polarizado 74 está ligado por meio de ligações mecanicas 76 ao mecanismo 60 para transmitir, por um lado, a esse mecanismo uma ordem de disparo e, por outro lado uma acção de rearmamento do relé 74 depois de uma manobra de disparo. Tais blocos diferenciais são bem conhecidos pelos especialistas e são, por exemplo, descritos na patente francesa citada anteriormente. Um defeito de terra traduz-se por um desiquilibrio entre as correntes que percorrem os enrolamentos primários 68, 70 que induzem uma corrente secundaria no enrolamen-The differential part 64 contains a differential transformer with toroidal core 66 with the primary windings of neutral 68 and phase 70 connected respectively to the connecting conductors 38, 40 and 54, 56. The differential transformer 66 has a secondary winding 72 that supplies a relay polarized 74. The polarized relay 74 is connected by mechanical connections 76 to the mechanism 60 to transmit, on the one hand, a firing order to that mechanism and, on the other hand, a relay 74 resetting action after a firing maneuver. . Such differential blocks are well known to those skilled in the art and are, for example, described in the French patent cited above. A defect in the earth results in an imbalance between the currents that run through the primary windings 68, 70 that induce a secondary current in the winding.
