SIRIUS direct online starter — size S00, 0.8 A, 180 kW
The 3RA2110-0HH15-1BB4: It ships as a pre-assembled unit including the 3RT2015-2BB41 contactor, the 3RA2911-2AA00 link module, and the 8US1251-5DT11 busbar adapter — everything needed to snap onto a 60 mm busbar system and wire the main circuit via spring-loaded terminals. The vertical mounting position and the clearance requirements (50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side) should be checked against the enclosure layout before installation.
What the 0.8 A AC-3 rating means for motor control
The AC-3e rating at 400 V is also 0.8 A, confirming the same capability under the enhanced IEC/EN 60947-4-1 test cycle. The maximum AC-3 voltage is 690 V, giving headroom for 480 V or 600 V line supplies. The operating temperature range of -20 to +60 °C covers most industrial environments, and the storage/transport range of -50 to +80 °C means it can sit in a warehouse or truck without issue.
Current production — sourcing and compliance
For BOM planning, the dimensions are 155 mm depth, 45 mm width, and 260 mm height — the 45 mm width is a single S00 module slot on a 60 mm busbar system. The spring-loaded terminals accept solid or stranded copper wire without needing ferrules for the main circuit, which speeds up panel wiring.
