BBCB Series Intelligent MCCB’s - Moulded Case Circuit Breaker’s

Moulded Case Circuit Breaker (MCCB)is new circuit breakers which combined the international advanced design, manufacturing technology and develop . According to its rated limit short circuit sectional capacity (ICU), is divided into L-type (standard type), M-type (high break type), H-type (higher break type).It has the characteristics of small size, high breaking, short flying arc and anti-vibration, and is an ideal product for land and ship use. Its rated insulation voltage 800V (BBCB-63 is 500V), suitable for AC 50HZ, 690V and the following circuit for continuous frequent conversion and motor infrequent start-up. Circuit Breaker has overload, short circuit and under-voltage protection device, which can protect the line and power equipment from being damaged. Vertical installation and horizontal installation Meet the standards: IEC60947-2、GB14048.2
