It integrates a motor starter protector (MSP) and contactor in one Fastbus-mount package, saving panel space and wiring time compared to separate components. The 0.18-0.25 A range means it's sized for small motor loads — think fractional-horsepower pumps, fans, or conveyors — where a single device handles short-circuit and overload protection plus switching. The 110 VDC control voltage is the coil rating — verify your control supply matches before wiring. The 0.18-0.25 A current range is the motor full-load current setting on the overload relay, not the contactor's thermal rating; set it to the nameplate FLA of the motor.","metaTitle":"Siemens 3RA1120-0CD23-0BB4 Combination Starter","metaDescription":"Siemens 3RA1120-0CD23-0BB4 nonreversing combination starter, SIRIUS S0, 0.18-0.25A, 110 VDC control, UL listed.
