Type 2D-AS ROTOVERTER® Rotary Phase Converters With automatic motor starter

cUL - U.S. Listed

ROTOVERTER

Automatic start units are supplied with a contactor and associated controls to integrate with equipment that may cycle automatically from control circuitry containing timers, level or pressure sensors, etc., to bring the rotary transformer to speed before the load is energized, as required by NEC Article 455-21.

Description

Patented ROTOVERTER tap adjustments give you control over all three phases for balancing currents. Type D ROTOVERTER models are recommended for applications where a single load (of either single or multiple motors up to 42 HP) is operated and for non-motor load applications.

These models are sized to the largest three-phase motor based on full-load amp (FLA) rating or total motor horsepower to be operated at one time.
