Abstract: The present invention relates to an adapter device for connection of a low voltage switching device to a distribution bus bar system. The adapter device comprises a body provided with a front wall, which can be connected to the switching device, and a back wall, opposite the front wall. The device comprises first electrical terminals susceptible to electrically contact one of the distribution bus bars and second electrical terminals. The device also comprises first electrical connections electrically connected to first electrical terminals and which can be coupled with corresponding third electrical connections of the switching device. The adapter device is also provided with second electrical connection means connected to corresponding second electrical terminals and which can be coupled with corresponding fourth electrical connections of the switching device.

Abstract: The present invention relates to a magnetic protection device, in particular for an automatic circuit breaker or a disconnecting switch, preferably for use in low voltage systems. The invention also relates to an automatic circuit breaker comprising this device. The protection device (1) according to the invention comprises a low voltage circuit breaker comprising an air gap magnetic circuit (T), provided with a first portion (10) forming a first surface (11) of said air gap (T) and a second portion (20) forming a second surface (21) of the air gap (T). The first portion (10) constitutes a fixed section of the magnetic circuit, while the second portion (20) constitutes a moving section of the magnetic circuit. The magnetic circuit also comprises a flexible portion (30) that connects the first portion (10) to the second portion (20) with continuity, forming an intermediate section of magnetic circuit interposed between the fixed section and the moving section.
