FAQs

 

What is the function of the NQ1 Star-Delta Starter?

It automatically switches motor windings from star to delta after startup to reduce inrush current and mechanical stress during motor starting.

 

What types of motors can it control?

The NQ1 is suitable for three-phase AC squirrel cage induction motors up to 55 kW at 380 V AC.

 

How does it protect the motor?

It integrates overload, phase loss, under-voltage, and short-circuit protection through built-in relays and control circuitry.

 

Is the NQ1 easy to install and maintain?

Yes — the pre-wired, integrated design simplifies installation and reduces wiring errors, making it suitable for compact control panels.

 

What are typical applications?

The NQ1 is used in pumps, compressors, fans, conveyors, and machine tools, where soft, reliable starting and protection are critical.
