Abstract

Electrical switchgear for simultaneous protection against excess currents, short-circuit currents and fault currents in individual circuits require the simultaneous use of a line circuit breaker and of a fault current circuit breaker. Such known switchgears, termed line and fault current circuit breakers, occupy a comparatively large amount of space in the distribution units because of the large space requirement of the fault current circuit breaker. The object of the invention is thus to develop switchgear which requires less space. To achieve this object it is proposed that the fault current protection pole of the single-pole switchgear also be arranged in a housing of modular construction, an auxiliary switch mechanism being connected between the fault current trip device (60) and the main switch mechanism, to compensate for the reduced tripping force of the fault current trip device (60), whose dimensions are limited, which auxiliary switch mechanism amplifies the trip pulse transmitted by a trip cam (61) of the fault current trip device (60) and thus leads to unlatching of the main switch mechanism. The principle of the construction of the auxiliary switch mechanism (44) is shown in a schematic representation, the sequence of the switch action being explained by instantaneous recordings of intermediate positions. <IMAGE>
