Hybrid motor starter
Woehner USA’s hybrid motor starter, Motus ContactronControl, offers system designers unique advantages in space and labor savings, while delivering versatile, reliable and long-lasting motor control.
Targeted at industries using motor controlled motion, Motus is used in place of traditional motor starting components. It is perfectly suited for system or machine designs that require motor loads of up to 5 hp.
Motus is also the first hybrid motor starter that not only incorporates three mounting options – 60mm System Classic, 60mm System Compact and DIN-rail mounting, but also incorporates short-circuit protection into the housing of the device, eliminating the need to mount circuit protection elsewhere in the panel design.
Motus is a hybrid device because it uses a solid-state semiconductor switch to start and stop motor loads at up to 5 hp, at 480 volts ac. The advantage of using a hybrid motor starter lies in the non-mechanical nature of the semiconductor switch. Hybrid motor starters can achieve up to 10 times as many switching operations as a mechanical contactor. Once the motor load is brought up to speed, the current is shunted through a traditional set of contacts to insure cool operating temperatures.
