Types of high voltage circuit breaker As we know about circuit breaker is to protect electrical equipment from abnormal condition such as over load current or short circuit.For Low voltage circuit breaker,i already explain on my last post.Please read my post about miniature circuit breaker (MCB),molded case circuit breaker (MCCB) and residual current circuit breaker [...]
As we know,Molded Case Circuit Breaker main function is protection device from overload current and short circuit.It also have a several attachment device for additional protection that we can combine with MCCB. Common accessories used for MCCB such as phase insulation barrier,Shunt trip,Under voltage trip device,rotary handle and change over system.It can provide more protection [...]
Before we make a decision to install Molded case circuit breaker for our application,firstly we need to know about types of MCCB.It important information that we must know to make sure our MCCB can functioning properly to protect our application from electrical failure. As we know the main function of MCCB are to protect our [...]
Circuit breaker is a one of important protection device when installing of electrical induction motor.This time i want shared some information about the major parameter that we need consider when applying Molded case circuit breaker(MCCB) for electric motor. If we not selected the right MCCB for our electric motor application,it will effected to the system [...]
What is Vacuum circuit breaker? As we know vacuum mean the the pressure is maintained below atmospheric pressure( unit : mmHg ).So the manufacture made a research and development to design the vacuum circuit breaker based on current cannot jump in vacuum condition. This breaker used the vacuum pressured to extinguish the current arc when [...]
Circuit breaker specification for MSB. For circuit breakers specification MUST suitable with installation condition and needed.Main switchboard is the main power supply distribution for factory or building.This unit is a key for entire electrical power supply distribution. It feed the high volume of voltage for all equipment and machine.It also have a high value of [...]
Low circuit breaker normally operating at 600 volt AC and below.The common used types of circuit breaker around the world such as molded case circuit breaker (MCCB) and Air circuit breaker ( ACB ). This low voltage circuit breaker usually used for power distribution and sub power distribution at factory and general industry.It a combination [...]
Routine maintenance tests Circuit breaker is the important protection device for our application and electrical power supply system.It can save our equipment or machinery from damage from over current or overload matter.It also can save personal life who involve directly or indirectly with electrical application from electric shock. How we can know the actual condition [...]
