Manual Motor Starters and Motor Starter Combinations
Electric motors and the applications they provide
are valuable assets in modern industrial facilities.
They are exposed to strong load variations
depending on the way they are incorporated into
the production process.
Manual motor starters from ABB switch motors
on and off properly and protect them in case of
overload and short circuit.
The ABB manual motor starter know-how
increases the reliability and availability of the
plant thanks to the extremely quick short circuit
cut-off in cases that could cause motor damage.
Therefore, ABB motor starter combinations
provide for reliable, cost-efficient solutions for
all your motor protection needs.
