FAQ
Q:What is difference between MCCB and MCB?
A:The MCB is mainly used for low circuit currents, while the MCCB is used for heavy current circuits. the MCB is used for low energy requirements (domestic), while the MCCB is used in areas with high energy requirements (large industrial).
Q:Do you test all your goods before delivery?
A:We would take strict test of quality and performance in specialized quality testing room before delivery.
