Allen-Bradley SMC-3 Series Technical Notes

The Allen-Bradley SMC-3 (Bulletin 150) is a solid-state, reduced-voltage smart motor controller designed for three-phase AC induction motors. Deployed across global heavy industry — including petrochemical refineries, nuclear auxiliary systems, offshore platforms, and continuous-process chemical plants — the SMC-3 series occupies a critical position in motor protection and soft-start infrastructure. Its integrated current-limiting soft-start, soft-stop, and pump control functions make it a standard specification item in IEC and NEMA motor control centers (MCCs) worldwide. The series covers a current range from 3A to 1250A, accommodating motor loads from fractional horsepower to several hundred kilowatts.
