SIRIUS S0 overload relay — panel fit and terminal capacity
The Siemens 3RU6926-3AA01 is a SIRIUS-brand overload relay in size S0, designed for individual (stand-alone) mounting. It fastens via screw and snap-on onto a 35 mm DIN rail, so it integrates into standard control-panel layouts without extra brackets. Main-circuit terminals are screw-type, accepting solid or stranded copper from 1 to 10 mm² (AWG 16 to 8) per conductor, and finely stranded with core-end processing from 1 to 6 mm². That covers the common motor-circuit wire sizes for a size S0 relay.
Environmental limits and compliance
RoHS compliance date is 03/01/2017 — the relay meets the EU substance prohibitions effective from that date.
