65 A AC-3 direct starter, S2 size — what the ratings mean
The 3RA2130-4JA37-0NB3: The unit ships with a 3RT2037-1NB30 contactor and a 3RA2931-1AA00 link module pre-assembled, so it's a coordinated starter package, not a build-up from loose parts.
Mounting and panel fit
Mounts via screw fixing or snap-on to two parallel 35 mm DIN rails, in vertical or horizontal orientation. The dimensions — 274 mm height, 55 mm width, 150 mm depth — put it in the S2 footprint, which is the standard size for this current class in the SIRIUS family. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the sides, and 0 mm backwards (the back sits flush against the mounting surface).
Environmental and compliance
Operating temperature range is -20 to +60 °C, with storage and transport limits of -50 to +80 °C. The substance prohibitance date of 03/01/2017 indicates RoHS compliance per the EU directive — the starter meets the restricted-substance requirements for equipment placed on the market after that date.
