It is rated for motor loads up to 2 hp at 460/480 V (AC-3) and delivers 3.95 A at 480 V, with a Class 10 trip curve that clears overloads before the motor windings overheat under locked-rotor conditions. ## Mounting and panel fit Dimensions are 167.2 mm high by 45 mm wide by 97.1 mm deep — it fits standard S00 feeder slots without protruding beyond the panel depth envelope. ## Coil voltage and wiring The coil accepts 93.5–121 V at 50 Hz and 96–132 V at 60 Hz, covering common 110/120 V control circuits without a separate transformer tap.","metaTitle":"Siemens 3RA2115-1EA15-1AK6 SIRIUS Motor Starter","metaDescription":"Siemens 3RA2115-1EA15-1AK6 SIRIUS non-fused motor starter, size S00, Class 10 thermal overload, 2 hp at 460/480 V.
