Pre-configured motor starter block — what is inside
This 3RA2115-1JA16-1BB4 is a SIRIUS non-fused motor starter (product designation 3RA2) in size S00, assembled as a direct starter from the factory. It ships as a pre-matched block: the supplied contactor is 3RT2016-1BB41 and the supplied link module is 3RA1921-1DA00. The overload release is thermal bimetallic (CLASS 10), and the short-circuit trip is magnetic — so the starter provides both overcurrent and short-circuit protection in one package without needing a separate overload relay.
Motor ratings across the voltage range
Rated motor power at 400 V is 4,000 W; at 500 V it is 5,500 W. Rated current at 480 V is 7.6 A; at 600 V it is 9 A. Horsepower ratings span 2 hp at 200/208 V up to 7.5 hp at 575/600 V. The maximum AC-3 operating voltage is 690 V, and the operating frequency is 50...60 Hz. The 24 V coil (rated value) means it integrates into standard 24 VDC control circuits without a separate power supply step-down.
Panel fit and mounting
Width is 45 mm, height 167.2 mm, depth 97.1 mm. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side, 0 mm forwards and backwards. Fastening is snap-mounted to DIN rail or screw-mounted with an additional push-in lug. Mounting position is vertical. AWG equivalents: 2x (20...16), for contactor 2x (18...14), 2x 12. Pollution degree 3 — suitable for industrial environments with conductive pollution.
Environmental limits and storage
Operating temperature range is -20... +60 °C; storage range is -50... +80 °C; transport range is -55... +80 °C. These cover most panel and warehouse conditions without special derating.
