Problems solved by technology

[0005] However, these techniques for positioning the auxiliary modules in the housing are sub-optimal as they would leave too much dimensional dispersion between the different parts of the device

Embodiment Construction

[0031] The electrical switching apparatus 10 comprises a housing 15, a first switch member 20A, a second switch member 20B, a third switch member 20C, a control mechanism 25 for each switch member 20A, 20B, 20C, a mechanical reference member 30 and at least one Auxiliary module 35.

[0032] The switching device 10 is adapted to receive a first current via an input electrical conductor and deliver the first current to an output electrical conductor, and vice versa.

[0033] Preferably, the switching device 10 is adapted to receive a plurality of first currents through several input conductors, and to deliver each first current to a respective output conductor. exist figure 1 In , the switchgear 10 is a three-phase circuit breaker.

[0034] For the switchgear 10 there is a defined vertical direction Z, transverse direction Y and longitudinal direction X. Each of the vertical direction Z, the lateral direction Y, and the longitudinal direction X is at right angles to the other...

Abstract

This electrical switching apparatus includes a protection casing, at least one switching member suitable for switching between a first position permitting the passage of a current and a second position preventing the passage of the current, a mechanism for control of the or of each switching member, and at least one auxiliary module disposed in the casing, the auxiliary module being removable with respect to the casing and configured to implement a function associated with the control mechanism. The electrical switching apparatus includes a mechanical referencing member common to the control mechanism and to each auxiliary module, for the positioning of the control mechanism and of each auxiliary module in the casing.

Description

technical field [0001] The invention relates to an electrical switching device comprising a protective housing, at least one switching member, a control mechanism for the switching member and at least one auxiliary module. Background technique [0002] Switching devices, such as circuit breakers, often comprise one or several switching members configured to transmit current between two connecting lugs and, if necessary, interrupt the current, thereby isolating the two lugs from each other. When such switchgear is used in a multi-phase power distribution network, the switchgear usually comprises switching means for each phase. In such configurations, the switch member is typically controlled by a common control mechanism, separate from the switch member. Furthermore, this configuration makes it possible to ensure that the current flow of different phases is indeed interrupted when a fault on any phase is detected. [0003] From document EP0591074A1 is known a circuit breake...
