It mounts via screw and snap-on to two 35 mm DIN rails, so plan for a twin-rail section in the panel layout. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side. Backwards clearance is zero — the unit sits flush against the backplane. Vertical or horizontal mounting position is acceptable. ## Rated current and trip coordination — AC-3 and Class 10 That means it handles standard and IE3/IE4 motor starting currents without derating. At 480 V the rating drops to 65 A; at 600 V it's 62 A. The overload is thermal, not electronic, so no auxiliary power is needed for the protection function. Rated insulation voltage is 690 V, and the operating frequency is 50/60 Hz. The control circuit voltage is 230 V at 50 Hz. ## What's in the box — supplied contactor and link module This is a fully assembled direct online starter — it ships with the contactor (3RT2038-1AP00) and the link module (3RA2931-1AA00) already integrated. The main circuit uses screw-type terminals, so no special crimp tooling is needed for installation. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. The substance prohibition date of 03/01/2017 indicates RoHS compliance per Siemens' declaration.","metaTitle":"Siemens 3RA2130-4KA38-0AP0 SIRIUS Motor Starter, 73 A AC-3","metaDescription":"Siemens 3RA2130-4KA38-0AP0 SIRIUS direct online motor starter, 73 A at 400 V AC-3, Class 10 trip, S2 size.
