Product Description

 

Product Description

 

Product description:

MTW1 series universal low-voltage circuit breaker is suitable for distribution networks with AC 50Hz, rated voltage up to 660V (690V) and rated current below 400A~6300A.

It is used to distribute electrical energy and protect lines and power equipment from overload, undervoltage, short circuit, single-phase grounding and other faults.

It has intelligent protection function, precise selective protection, can improve power supply reliability, and avoid unnecessary power outages.

The circuit breaker complies with standards such as GB14048.2 and IEC947-2
 

Working principle:

The air circuit breaker monitors the current in the circuit in real-time through a current transformer. And transmit the current signal to the intelligent controller.

After the intelligent controller detects the abnormal current, it will disconnect the contacts inside the circuit breaker and cut off the circuit
