Holds in at 0.7 of rated voltage.
At 45 mm wide and 116 mm tall, it fits a standard panel layout. Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, up to 2x 4 mm² max. Auxiliary terminals handle 2x (1 to 2.5 mm²) solid or 2x (2.5 to 6 mm²) stranded, max 2x 10 mm². That covers most panel wiring without needing ferrules.
RoHS compliance date is 01.05.2012.
RoHS compliance is confirmed with a date of 01.05.2012. Standard Siemens declarations for CE, UL, and CSA are typical for the SIRIUS series, though not explicitly listed here.
