Abstract

The earth leakage current protection switch Ä10Ü has a base Ä11Ü that clips onto a rail Ä16Ü mounted onto a power busbar Ä17Ü. The unit has a total current converter Ä18Ü that connects with the primary winding Ä19Ü and has a pair of plug contacts Ä25Ü that engages the fixed contacts Ä20Ü that are set into a slot Ä27Ü in the base. The contacts extend into connector pins Ä26Ü in the bus bar.
