Product Q&A

Q:What is the main application of this starter?

It is applicable to mines with explosive gas and coal dust, suitable for centralized monitoring of mining, transportation, and working faces with concentrated power loads.

Q:How many motors can this starter control?

It can control and protect the starting and stopping of 6 or less three-phase squirrel cage asynchronous motors at the same time.

Q:What protection functions are included?

It features overload, short circuit, leakage blocking, undervoltage, overvoltage, three-phase imbalance, phase failure, power metering, and communication networking.

Q:What is the voltage operating range?

The switch can work reliably within 75%-110% of the rated control power supply voltage and release when the voltage is 20%-60% of the rated value.

Q:What is the short-circuit protection response time?

The action time for short-circuit protection is 0.2-0.4 seconds when the main circuit current reaches the set short-circuit multiple.
