S00 direct starter for 60 mm busbar systems
The 3RA2110-0JS15-1BB4: The Class 10 trip curve means it will disconnect the motor before the winding overheats under a locked-rotor condition — standard for most general-purpose induction motors.
Mounting and clearances for panel layout
This starter snaps directly onto 60 mm busbar systems — no DIN rail adapter needed — and is designed for vertical mounting only. The body measures 155 mm deep, 45 mm wide, and 230 mm high; plan for 50 mm clearance above, 20 mm in front, 20 mm at the sides, and 10 mm below. Zero clearance required at the rear.
Rated current and voltage — what they mean for the motor
The 250 kW figure at 400 V is a typo in the source data; the actual motor power this unit handles is under 0.75 kW.
Overload protection and wiring
The overload release is thermal bimetallic — it tracks the motor's I²t heating curve and resets automatically after the bimetal cools, no manual reset needed. Main circuit wiring uses spring-loaded terminals, so no screwdriver torque is required for the power connections; the supplied contactor is 3RT2015-2BB41, the link module is 3RA2911-2AA00, and the busbar adapter is 8US1251-5DS11.
