It handles motor reversing and overload protection in a single panel footprint, saving the space and wiring of separate contactor/breaker assemblies. The coil pulls 24 VDC (24 V nominal, AC/DC type), so it drops into a standard 24 V control supply without a separate rectifier. Trip class is adjustable between CLASS 10 and CLASS 20, giving you the choice of faster trip for sensitive loads or a longer thermal budget for high-inertia starts. Main circuit connections use spring-loaded terminals accepting 2x (0.25 to 1.5 mm²) solid or stranded. That eliminates screw-torque checks on the power side — strip, insert, done. At 191 mm tall, 90 mm wide, and 165 mm deep, the 3RA6250-2EB32 fits a standard motor-starter slot in most industrial enclosures. Mount it vertically on a horizontal DIN rail as recommended for proper heat dissipation from the bimetal trip. Three integrated LEDs indicate the operating state — run, overload trip, and short-circuit trip — so a tech walking the line sees the fault condition without opening the panel door. Shock-rated to 6g (10 ms pulses) and vibration-tested to 5.8 Hz at 15 mm amplitude, then 20 m/s² up to 500 Hz, so it holds up on a machine frame or conveyor section. For a direct functional cross-reference within the SIRIUS family, the 3RA6250-2EB31 is the same reversing compact starter with a different coil voltage — check your control supply before substituting. No second-source outside the SIRIUS range carries the same 53 kA SCCR in a 90 mm reversing package.","metaTitle":"Siemens 3RA6250-2EB32 SIRIUS Reversing Compact Starter","metaDescription":"Siemens 3RA6250-2EB32 SIRIUS reversing compact starter rated 53 kA at 400 V, 24 VDC coil, adjustable trip class 10/20.
