S00 direct starter with CLASS 10 trip curve
The Siemens 3RA2110-1ED15-1AP6 is a non-fused motor starter from the SIRIUS family, size S00, configured as a direct starter. It ships as a pre-assembled unit: the contactor (3RT2015-1AP61), thermal overload relay, link module (3RA1921-1DA00), and busbar adapter (8US1251-5DS10) are all included — no separate ordering of subcomponents needed. The overload release is thermal bimetallic, so ambient temperature compensation is built in, but the unit should still be mounted vertical per the spec to avoid nuisance trips.
Rated motor power across common line voltages
At 400 V AC-3, the starter is rated for 1.5 kW motor output; at 480 V it draws 3.95 A, and at 600 V the current rating is 4 A. Horsepower ratings span from 0.13 hp at 110/120 V up to 3 hp at 575/600 V — covers most small three-phase motors in North American and European panels. Coil voltage is 187–242 V at 50 Hz and 192–264 V at 60 Hz, so it works on 208–240 V control circuits.
Snap-on busbar mounting and panel clearance
Mounting method is snap-on onto 60 mm busbar systems — no DIN rail required, which saves panel depth. The overall dimensions are 45 mm wide, 200 mm high, and 155.1 mm deep. Clearance requirements: 20 mm upward, 10 mm downward, 9 mm at the side, and zero forward/backward — tight stacking is possible.
