S00 direct starter for 60 mm busbar systems
The Siemens 3RA2110-1CH15-1AP0 is a SIRIUS direct online starter in the compact S00 frame size, designed to snap directly onto 60 mm busbar systems — no separate DIN-rail adapter needed for the power feed. It ships as a pre-assembled unit containing a 3RT2015-2AP01 contactor and a 3RA2911-2AA00 link module, saving panel build time on repetitive motor-start circuits.
Class 10 trip and power ratings across common voltages
Rated 750 kW at 400 V, with horsepower ratings spanning 0.1 hp at 110/120 V up to 2 hp at 575/600 V — covers most fractional-to-small integral-horsepower motors in North American and IEC voltage systems. Main circuit connections use spring-loaded terminals — no screw torque check needed, and the clamping force stays consistent across temperature cycles.
Mounting dimensions and clearance envelope
The unit measures 45 mm wide by 260 mm tall by 155 mm deep — the S00 width fits two starters per 100 mm of busbar length, leaving room for finger ducts between them. Clearance requirements: 50 mm above, 20 mm below, 20 mm to the side, and 20 mm forward — plan the enclosure depth and gland-plate layout accordingly.
