Panel fit and mounting — size S00 on 60 mm busbars
The 3RA2110-0BD15-1AK6: This is the SIRIUS 3RA2 non-fused load feeder in size S00, a direct starter that integrates the contactor, overload relay, and short-circuit protection into a single 45 mm wide package. It snaps onto 60 mm busbar systems, so the panel layout starts with the busbar pitch — not a DIN rail — and the 45 mm width per feeder sets the horizontal fill factor. The mounting position is vertical only, with 20 mm clearance upwards and 10 mm downwards for ventilation and wiring access. Depth is 155.1 mm, height 200 mm — the depth is the dimension that governs enclosure depth when the feeder is mounted on a busbar system at the back of the panel.
Motor protection — CLASS 10 trip and AC-3 switching ceiling
This is the standard for general-purpose motor starting where the acceleration time is under 10 seconds; a longer CLASS 20 or CLASS 30 would be needed for high-inertia loads like fans or centrifuges. The short-circuit trip is magnetic, and the supplied circuit-breaker is the 3RV2011-0BA10. Operating frequency is 50/60 Hz, and the control supply voltage is 110 V at 50 Hz or 120 V at 60 Hz. The power dissipation at the coil is 60 W at 400 V and 690 V, which matters for the thermal budget inside a sealed enclosure.
Supplied subcomponents — what arrives in the package
This order code ships as a pre-assembled unit containing the 3RT2015-1AK61 contactor, the 3RA1921-1DA00 link module, the 3RV2011-0BA10 circuit-breaker, and the 8US1251-5DS10 busbar adapter. The degree of pollution is 3, meaning the unit is rated for conductive pollution environments typical of industrial control panels where occasional condensation occurs. The operating temperature range is -20 to +60 °C, with storage and transport limits of -50 to +80 °C.
The RoHS / REACH substance compliance date is 10/01/2009, indicating the design meets the EU directive requirements for the materials used.
