Product details

It measures 45 mm wide by 73 mm deep, fitting standard panel layouts without special adapter plates. Rated for 10 A at both 24 V and 230 V, it handles typical control-circuit loads — pilot lights, relays, PLC inputs — across common voltage levels. The contact block carries 3 instantaneous contacts (NO/NC configuration not specified in this data).

Terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². Strip length and ferrule sizing follow standard Siemens practice for the S00 frame.
