KM2 MOULDED CASE CIRCUIT BREAKER(MCCB)

   KM2 series moulded case circuit breaker is one of the most advanced type breakers in the world,which adopt international advanced design and manufacture technology.They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz,rated current from 12.5A to 630A.Its rated insulation voltage is 690V.It can make and break non-frequently the circuit in the nomal conditions.it makes protective effect when mouse cage motors non frequent start,breaking off working and protecting overload,short circuit and lacking voltage.

FAQ

 

Q 1.How about your experience?

A.We have our own professional factory and R&D department & more than 15 years producing experience.

Q 2. What's your advandge ? 

A. We have mash melders,injection molding machines and punchers,with these,we can make by ourselves from the inside parts to outside.

It greatly increases the efficiency and saves the cost.

Q 3. How's the delivery time ? 

A. usually it will take about 15-30 days for production

Q 4. Tell me the standard of package? 

A. For inner box and master carton are made as per international standards,and we can make special design for you if need.

Also if necessary, will be packed in pallet to avoid any damage.

Q 5. What kind of material of circuit breaker? 

A. We have two types, one copper coil with silver point and the other is brass coil with copper 

point. It depends on your requirement. In fact, those two have no difference if normal work well. 

Only except the electrical life. Copper and silver is better and also higer price.

Q 6.Will be any wanrranty for your item ? 

A. We offer one year warranty for our products. Please feel assured.

Q 7 .Could you offer Form A or C/O ?

other office to apply for this certificate. 

Q 8.Would you accept to use our logo ? 

A.We offer OEM ODM customization services if quantity is suitable.

Q 9.We want to know month capacity.   

A. 1000pcs/month 

Q10 .Where is your market? 

A. Our produce and design are sold well in Southeast Asia , Middle East and European, also are trusted and praised deeply by domestic and foreign users.
