What this starter is and what it carries
The Siemens 3RA2130-4VA36-0NB3 is a SIRIUS direct-on-line starter in Size S2, supplied as a factory-assembled unit with a 3RT2036-1NB30 contactor and a 3RA2931-1AA00 link module.
Mounting and panel fit
Fastens by screw or snap-on to two 35 mm DIN rails, acceptable in vertical or horizontal orientation. The enclosure footprint is 55 mm wide, 274 mm tall, and 150 mm deep — a compact S2 form that leaves room for adjacent feeders in a crowded panel.
Environmental limits and compliance
Operates from -20 °C to +60 °C with temperature compensation built in. Storage and transport range is -50 °C to +80 °C. The substance prohibitance date of 03/01/2017 aligns with RoHS/REACH compliance milestones. Clearance distances: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, and 0 mm backwards — useful when laying out gland plates and busbars.
The 3RA2931-1AA00 link module and 3RT2036-1NB30 contactor are standard SIRIUS components, so spares are straightforward.
