Busbar-mount direct starter for 60 mm systems
The Siemens 3RA2110-1CS15-1BB4 is a SIRIUS direct-on-line starter in size S00, designed to snap onto 60 mm busbar systems — no DIN rail adapter needed in busbar-fed panels. The Class 10 trip characteristic means it will disconnect before the motor windings overheat under locked-rotor conditions — standard for most general-purpose motor protection.
Panel fit and clearance envelope
Envelope dimensions are 155 mm deep × 45 mm wide × 230 mm tall. Mounting is vertical only. Clearance requirements: 50 mm above, 20 mm forward, 20 mm at the sides, 10 mm below — zero clearance needed behind the unit since it clips directly onto the busbar. Operating temperature range is -20 to +60 °C, with storage and transport limits from -50 to +80 °C. The 24 V control voltage is fixed — no dual-voltage coil option on this variant.
Sourcing — active production, quoted per BOM
For volume purchases or project builds, the spread is in the gap between list and negotiated pricing — confirmed at RFQ with lead time tied to the order quantity.
