Abstract

2.1 Fault-current protection switches for different rated currents have been in use for a long time in different designs with considerably different dimensions. Because of a requirement for a switching performance of 10 kA with a back-up fuse of 100 A, it is unavoidable to search in new ways for fault-current protection switches which cover a range of rated currents from 16 to 125 A. 2.2 The invention exhibits a fault-current protection switch which, based on a four-way basic switch for 63 A (module width 4M), covers the complete protection range from a two-way design for 40 A (module width 2M) up to the four-way design for 125 A (module width 5M). An extinguishing device (9), a contact set (10) and a drum controller (11) for each switch pole are inserted, corresponding to the width of a module (1M), in all switches in a lower part (1) of the housing, and a switch locking mechanism (12), including a trip device (14) having a module width (1M), a summing current transformer (13), a test device (15) and a contact position indicating device (16) are arranged in the upper part (3) of the housing. The high content of common components and the assembly sequence which is always the same, that is to say the virtually identical internal construction of the switches for different rated current intensities, leads to a switch family which extends from two-way fault-current protection switches which are 2 modules wide up to four-way fault-current protection switches which are 5 modules wide. 2.3 Such fault-current protection switches are provided for high powers in low-voltage networks. <IMAGE>
