The 3RA2110-1FD15-1BB4 is a Siemens SIRIUS direct-on-line (DOL) starter, size S00, combining a contactor and overload relay in one package for snapping onto 60 mm busbar systems. The 24 V DC coil (24... 24 V rated value) keeps control voltage low for PLC-driven cabinets; the screw-type main terminals accept standard power wiring without special tools.
Mounting and panel fit — busbar snap-on, vertical only
Designed for 60 mm busbar systems — snaps directly onto the busbar without a separate DIN rail adapter, saving one mounting step and keeping the panel depth tighter. Mounting position is vertical only, and the clearance requirements are: 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side, 0 mm backwards — plan the gland plate and wireway accordingly. Dimensions are 155 mm deep, 45 mm wide, 203 mm high — the 45 mm width fits a standard 45 mm module slot on the busbar, leaving room for adjacent feeders in a multi-motor group.
Duty ratings and trip coordination
Operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C — the starter can sit in an unheated warehouse and still start reliably when the panel warms up.
What ships in the box — supplied components
The starter ships with a 3RT2015-1BB41 contactor and a 3RA1921-1DA00 link module — these are the matched pair for the S00 frame, so you don't need to order the contactor and overload separately. The supplied contactor is the same 3RT2 series used across the SIRIUS line, meaning spare contactor blocks and coil replacements are common across multiple S00 starters in the same panel.
No minimum order threshold for standard quantities.
