A molded case circuit breaker, abbreviated MCCB, is a type of electrical protection device that can be used for a wide range of voltages, and frequencies of both 50 Hz and 60 Hz. The main distinctions between molded-case and miniature circuit breaker are that the MCCB can have current ratings of up

Most people do know what miniature circuit breaker is, but they may not know how miniature circuit breaker works, and how they protects from short circuit and overload, as they don’t know miniature circuit breaker construction, which is exactly the basic for knowing more about miniature circuit br

Each phase of conductor at the Residual Current Circuit Breaker passes through the zero-sequence current transformer, and the secondary side of coil connects with the electromagnetic tripper. Under normal condition, the vector sum of each phase of current passing through zero-sequence current transf

With the circuit breaker is becoming increasingly popular, many industries can use the family can also be used. But the moulded case circuit breakers relates to personal safety, can’t casually buy. If the quality of circuit breaker does not pass, will have very serious consequences. What MCCB You sh

Circuit breaker is circuit breaker. Leakage protector is leakage protector. These are two different products which the role and the application are also different.Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automa

KNB1-63 series Miniature Circuit BreakerInstalled with standard din rail it is convenient and easy in usage. It is mainly used in the line of AC 50/60Hz rated working voltage to 240V/415V, and rated current to 63Aas protection against overload and short-circuit.

Moulded Case Circuit Breaker MCCB 3p (KNM3 SeriesMODIFIED TYPE) with Ce CB160A/250AThe rated insulation voltage of this circuit breaker is 750V which is applicable for the electricity distribution network of AC50Hz, rated working voltage 690V and below, rated working current from 6A to 1600A. It is

KNLE1-63 series leakage breaker is suitable for the leakage protection of the line of AC 50)60Hz rated voltage single-phase 240V, rate document up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power
