SIRIUS contactors with a width of 45 mm (size S00/S0) come with a uniform, versatile range
of auxiliary switches and accessories, which are quick to retrofit and replace. The
accessories for contactor relays and power contactors are identical in design. The
accessories can be attached on the front or the sides of devices.
The 3RH2 contactor relays can be expanded to give versions with a maximum of 8 poles by
attaching 2-pole or 4-pole auxiliary switch blocks.
