What fits this S00 busbar footprint
The 3RA2115-0CH15-1FB4 is a SIRIUS direct online starter in the S00 frame, designed to snap onto 60 mm busbar systems — no DIN rail adapter needed. It ships as a pre-assembled unit: the 3RT2015-2FB41 contactor, a 3RV2011-0CA25 circuit breaker with magnetic short-circuit trip, and a thermal bimetallic overload relay set to CLASS 10 trip curve.
Clearance and mounting — no surprises
Dimensions are 155 mm deep, 45 mm wide, 260 mm tall. Mounting is vertical only. Minimum clearances: 50 mm above, 20 mm below, 20 mm at the sides, 20 mm forward, 0 mm backward — the back can sit flush against the panel. Operating temperature range is -20 to +60 °C with 10–95 % relative humidity; storage and transport tolerate -50 to +80 °C.
Termination and expansion
Both the main current circuit and the auxiliary/control circuit use spring-loaded terminals — no screwdriver torque check needed, just push in the stripped wire. The starter supports an auxiliary switch extension (product extension auxiliary switch: Yes), so you can add feedback contacts without a separate enclosure. The supplied busbar adapter (8US1251-5DT11) and link module (3RA2911-2AA00) are included — the starter is ready to clip onto the 60 mm system out of the box.
Lifecycle and sourcing
No direct second-source cross-reference is listed; the 6ES7517-3FP00-0AB0 is a Siemens PLC CPU, not a motor starter, and does not share the S00 busbar footprint or function.
