The manufacturer lists the lifecycle stage as current, but the description explicitly marks it as a phased-out product with a preferred successor: the SIRIUS 3RU2 series, specifically order code 3RU2936-3AA01. For new designs or BOM replacements, that successor is the direct drop-in path. The relay accepts solid conductors 1x (1... 50 mm²) and stranded conductors 1x (1... 50 mm²). Finely stranded wire with core-end processing (ferrules) is rated 1x (1... 35 mm²). AWG equivalents for main contacts are 1x (18... 1). These terminal capacities cover motor-circuit wiring up to 50 mm², typical for Size S2 overload relay applications. Dimensions are 111 mm depth, 55 mm width, 105 mm height. The 55 mm width matches the standard S2 contactor footprint, so it side-mounts directly to a SIRIUS 3RT2 contactor without extra panel space. The substance prohibitance date of 07/01/2006 indicates RoHS compliance per the EU directive.","metaTitle":"Siemens 3RU1936-3AA01 SIRIUS Overload Relay, Size S2, 111 mm","metaDescription":"Siemens 3RU1936-3AA01 SIRIUS Size S2 overload relay, screw terminals, 111 mm depth.
