Abstract

The invention relates to a low voltage switchgear with a bimetallic actuator, especially to a motor safety switch. The aim of the invention is to improve such a low voltage switchgear so that the fabrication and assembly tolerances are widely compensated for. To this end, the two-part (21, 22) housing (2) of the switchgear (1) is provided with an opening (23), that is closed with a protective cover (24). By way of said opening (23), the bimetallic component (51) and the jack system are accessible for the purpose of measurement and a bridge system (52) of the bimetallic actuator (5) that is calibrated on the basis of the measured values can be mounted therethrough.
