The Bulletin 1109 open-type starter is designed for use up to 1500V. Vacuum starters are particularly well-suited in mining, pumping, and other harsh environments where voltages above 600V are used.
The Bulletin 1109 line uses vacuum bottles to enclose the power‑switching contacts within the starter. The use of vacuum technology results in particularly effective arc extinguishing above 600V and results in a very compact, long-lasting starter.
