3.2 A at 400 V AC-3 — S00 frame direct-on-line starter
The 3RA2110-1DD15-1BB4: The control coil is 24 V DC, so it pulls in clean on a 24 VDC control bus without an AC hum or dropout from a sagging rectified supply.
Busbar snap-on — 45 mm wide, wires up clean
This starter is designed for snapping onto 60 mm busbar systems — it clips directly onto the busbar without a separate DIN-rail adapter, saving a module of width in a high-density panel. The envelope is 45 mm wide, 155 mm deep, 203 mm tall — that 45 mm width is the same as a standard S00 contactor, so it rows neatly on the busbar with adjacent feeders. Main circuit connections use screw-type terminals — torque them to the value on the contactor nameplate; the supplied link module 3RA1921-1DA00 bridges the contactor output to the overload block internally.
The starter ships as a pre-assembled unit: the 3RT2015-1BB41 contactor and the overload relay are linked and tested from the factory, so it lands on your bench ready to wire into the motor circuit.
