Direct-on-line starter for 60 mm busbar panels
The Siemens 3RA2110-1KH17-1BB4 is a SIRIUS direct-on-line starter, size S00, designed to snap directly onto 60 mm busbar systems — no separate DIN rail adapter needed for the main power feed. It ships as a pre-assembled unit: a 3RT2017-2BB41 contactor, a 3RA2911-2AA00 link module, and an 8US1251-5DT11 busbar adapter, all wired and tested together. The main circuit terminates through spring-loaded terminals, so you land the wires without a screwdriver.
Motor ratings and trip class that govern the load
The coil is rated 24 V DC, and the operating frequency is 50/60 Hz. The unit is designed for vertical mounting only, with minimum clearances of 50 mm upward, 20 mm forward, and 10 mm downward to maintain the thermal trip calibration.
