Product details

Sirius Soft Starter 37kW 72Amp 400VAC/230VAC

SIRIUS soft starters are the best solution when direct-on-line or star/delta starting are not suitable for three-phase motors, because mechanical impacts in the machine or voltage dips in the power supply system can often cause problems. A full and comprehensive range of soft starters with intelligent functions offers a softer alternative for almost every application.
