What this SIRIUS direct starter includes
The 3RA2115-0HE15-1FB4 is a factory-assembled SIRIUS direct (on-line) starter combining a contactor, overload relay, and circuit breaker in one size S00 package. It ships with a 3RT2015-2FB41 contactor, a 3RA2911-2AA00 link module, and a 3RV2011-0HA25 circuit breaker — all pre-wired and tested as a single unit. Rated for AC-3 motor switching up to 690 V and 50/60 Hz, it delivers 180 W at 400 V. The thermal bimetallic overload release is set to Class 10 trip, meaning it protects standard motors against prolonged overload without nuisance tripping on normal starting current.
Mounting and wiring constraints
Mounts vertically on a 35 mm DIN rail via screw and snap-on fastening, or directly with screws. The S00 footprint is 45 mm wide, 97 mm deep, and 198 mm tall — clearances of 50 mm upward, 20 mm forward, 20 mm to the side, and 10 mm downward are required for airflow and cable entry. Both main and auxiliary/control circuits use spring-loaded terminals — no screw torque to verify, but the stripped length and ferrule size must match the terminal spec. The unit includes an auxiliary switch (product extension auxiliary switch = Yes) for status feedback to the PLC.
Environmental and compliance notes
Storage and transport range is -50 to +80 °C. The NEMA degree of protection is listed as 'other' — for IP-rated enclosures, confirm the panel seal separately.
