The ZRMV is a solid-state high-voltage soft starter for squirrel-cage asynchronous and synchronous motors. Its 3kV, 6kV and 10kV model groups remain separate in the selection data so power, current and cabinet dimensions are not mixed across voltage grades.
Applications include pumps, fans, compressors, crushers, agitators and conveyors in power, building-material, chemical, metallurgical, steel and paper industries.
