Busbar-mount form factor and panel fit
The 3RA2110-1EH15-1AP0: This direct online starter snaps onto 60 mm busbar systems — no DIN rail required, which saves a mounting step and keeps the assembly height consistent across the feeder row. The enclosure measures 260 mm high, 45 mm wide, and 155 mm deep, so it fits in a standard 200 mm deep enclosure with clearance for the busbar stabs. Mounting position is vertical only; the clearance zones are 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side, and 0 mm backwards — the back face sits flush against the busbar. Plan the gland plate and cable entry accordingly.
Motor protection and trip coordination
The supplied contactor is a 3RT2015-2AP01, and the link module is 3RA2911-2AA00 — the starter ships as a pre-assembled unit, not loose components. Main circuit wiring uses spring-loaded terminals, so no screw torque verification is needed during commissioning.
Thermal environment and storage limits
The temperature compensation range matches the operating range, so the overload curve stays accurate across the full ambient span without manual adjustment.
