What this reversing starter carries and where it fits
The 3RA2210-1ED15-2BB4 is a SIRIUS reversing starter, size S00, built around the 3RT2015-1BB42 contactor and the 3RA1921-1DA00 link module. It's a factory-assembled pair that handles forward-reverse motor control in one footprint — no separate interlock wiring between two contactors. That 4 A figure at 400 V is the motor-switching current you size against — it governs the largest standard three-phase motor this starter can reverse under load.
Mounting and termination — busbar snap-on, screw terminals
Snaps directly onto 60 mm busbar systems — no DIN rail adapter needed. The mounting position is vertical, with 50 mm clearance upward, 32 mm forward, 10 mm to the side and downward, and zero clearance required at the back. That 90 mm width and 155 mm depth mean it fits a standard 600 mm deep enclosure with room for the outgoing cables. Main circuit connections are screw-type terminals — expect to torque ring or fork lugs per the terminal marking. The supplied link module handles the mechanical and electrical interlock between the forward and reverse contactors, so the only field wiring is the incoming power, motor leads, and the control voltage.
