Description

The reduced voltage starters (TX) are manufactured with the most advanced technology. They include a start/stop button station, an operation indicator, and a digital voltmeter that indicates the three line voltages with their historical maximum/minimum values, as well as the frequency.

The starter can also be ordered with a Manual-Off-Automatic selector for automatic operation.

When squirrel cage motors are started at full voltage, they generate currents of up to 600% of the rated current. These high current values can cause problems in the transformer, the power line, and even burn the motor. 

Reduced voltage autotransformer starters are designed to reduce the voltage to the motor during startup. Consequently, the current is reduced in proportion to the square of the voltage reduction, preventing the startup current from reaching high values that cause damage. This type of starter applies reduced voltage to the motor through an autotransformer with taps to allow motor starting at 50, 65, and 80% of the line voltage. 

The autotransformer is factory-set to 65% of the voltage.  

Optional Equipment

• Manual-Off-Automatic operation selector.
• Safety disconnect switch that cuts power when the cabinet is opened.
• Protection against low voltage, imbalance, and phase failure with Fasealert-3 model F3.
• Three-phase RMS digital ammeter with max current recording mounted on the cabinet door.
