Screw-type terminals on the main current circuit — no spring-cage option on this variant, so factor in a torque screwdriver for the power connections and allow tool access above the terminals (50 mm upward clearance is the minimum for screwdriver swing). The supplied link module (3RA2931-1AA00) bridges the contactor and overload — it's pre-assembled, so the only field wiring is the incoming line, motor leads, and the 20-33 V control coil circuit. ## Lifecycle and sourcing posture The 20-33 V coil range covers 24 VDC nominal supplies with margin for brownout — common in control panels with a 24 VDC bus, provided the supply holds above 20 V under load.","metaTitle":"Siemens 3RA2130-4EA35-0NB3 SIRIUS Direct Starter, Size S2","metaDescription":"Siemens 3RA2130-4EA35-0NB3 SIRIUS direct-on-line starter, Size S2, 32 A at 480/600 V, Trip Class 10, 20-33 V coil.
