Siemens SMFFF1 Toggle Operator Manual Starter

Siemens SMFFF1 Toggle Operator Manual Starter is a Class SMF, 1-pole flush-mount open motor starter designed for 277V control. This unit mounts behind a flush plate (no enclosure provided) and uses a manual toggle operator to energize and de-energize a single‑phase circuit. As part of the Siemens SMF family, SMFFF1 is intended for general‑purpose motor control in open installations where a compact, flush‑mounted starter is required, making it suitable for light industrial and commercial equipment such as fans, pumps, and conveyors where space is at a premium. Variants exist with pilot lights, for example SMFFF1P features a red pilot light.
