Kit completeness — what ships in the carton
The 3RA2115-0HA15-1BB4: This is a factory-assembled non-fused motor starter (product designation: non-fused motor starter 3RA2) that ships as a complete kit: a 3RT2015-1BB41 contactor, a 3RA1921-1DA00 link module, and a 3RV2011-0HA15 circuit breaker, all pre-mounted and wired on a common base. No holes in the box — the auxiliary switch is already fitted (product extension auxiliary switch: Yes), and the 1 NC auxiliary contact is wired in. The kit includes the thermal bimetallic overload relay and the magnetic short-circuit trip, so the motor branch is fully protected out of the carton.
Trip Class 10 — what it means for motor protection
The thermal bimetallic design tracks the motor's I²t heating curve, so it protects against sustained overloads without nuisance tripping on normal start-up inrush.
Panel fit and mounting clearances
Snap-mounted to 35 mm DIN rail or screw-mounted with the additional push-in lug — the size S00 footprint (45 mm wide × 167.2 mm high × 97.1 mm deep) fits standard distribution boards and motor control centres. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side, 0 mm forwards and backwards — tight enough for dense panel layouts. Mounting position is vertical only; the operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C.
Power ratings and voltage coverage
Rated motor power at 400 V is 180 W, at 500 V is 250 W, and at 690 V is 370 W — the maximum AC-3 voltage is 690 V, so this starter covers 400 V and 690 V industrial networks without derating the switching capacity. Operating frequency is 50 to 60 Hz; the control coil is 24 VDC with a holding power of 4 W. Surge voltage resistance is 6 kV, and the degree of pollution is 3 (conductive pollution typical in industrial enclosures).
