ACA, starter ACA, starter magnetic ACA, contactor ACA

Starters series ACA are intended for use in fixed installations for remote start direct connection to the network, stopping, and reversing three-phase asynchronous motors with squirrel-cage rotor of an alternating voltage 660 V, frequency 50 and 60 Hz. When the presence of three-pole thermal overload relays series PTT and RTL starters exercise protection controllable motors from overload invalid duration and currents that occur at the precipice of one of the phases. Starters suitable for use in control systems using microprocessor technology in the bypass including the interference suppression coil device or when thyristor control. Designed for remote start direct network connection and disable three-phase asynchronous motors with squirrel-cage rotor. Additional features: the reversal, in the presence of thermal relays protect motors from overload invalid duration, including those arising on a roll of one of the phases, changing the circuits of the windings Y/A.
