The 24 V DC coil keeps control power consistent across PLC-driven panels without an intermediate relay. ## Trip class and protection design The magnetic short-circuit trip handles fault clearing independently of the bimetallic thermal element, so a phase-to-phase fault is interrupted before the overload heater sees the full let-through energy. Vertical mounting position is specified; clearance requirements are 20 mm upward, 10 mm downward, and 9 mm at the side — tight enough for dense panel layouts but non-negotiable for thermal derating.","metaTitle":"Siemens 3RA2115-1EA15-1BB4 SIRIUS Motor Starter, 24 V","metaDescription":"Siemens 3RA2115-1EA15-1BB4 SIRIUS non-fused motor starter, 24 VDC coil, Size S00, Class 10, 2 hp at 460/480 V.
