It is essential lifesaving equipment used to protect the human body from electrical and is mandatory in many states for domestic installation. These are an extremely effective form of shock protection&widely used for protection from a leakage current of 30,100 & 300mA. Both phase and neutral wires are connected through a RCCB device.
#MCCB CIRCUIT BREAKER SERIES#
RCCB is generally used in series with an MCB which protects them from over current and short circuit current. It is the safest device to detect and trip against electrical leakage currents, thus ensure protection against electric shock caused by direct contacts. This residual current device is basically an electrical wiring device that disconnects the circuit whenever there is leakage of current flow through the Human body or the current is not balanced between the phaseconductor. RCCB stands for Residual Current Circuit Breaker. Its trip current may be fixed as well as adjustable for overload and magnetic setting. Its trip characteristics are normally not adjustable since they basically cater to low circuits. MCCB is mainly used for both low and high Breaking capacity requirements mainly industrial. Judging from their power capacities, MCB is mainly used for low Breaking capacity requirement mainly domestic. Their interrupting current ranges from around 10KA -85KA Its interrupting current rating is under 10KA It stands for Molded Case Circuit Breaker. It offers adequate protection whenever an application requires discrimination, adjustable overload setting or earth fault protection.
#MCCB CIRCUIT BREAKER GENERATOR#
MCCB can be used for protection of capacitor bank, generator protection and main electric feeder distribution. The wide current ratings and high breaking capacity in MCCB find their use in industrial applications. It can be used for higher current rating and fault level even in domestic applications. The MCCB provides protection against overload, short circuit faults and is also used for switching the circuits. It is another type of electrical protection device which is used when load current exceeds the limit of a miniature circuit breaker.
MCCB stands for Molded Case Circuit Breaker. MCB works on bi-metal respective principle which provides protection against overload current&solenoidshort circuit current. MCB can be reset very fast & don’t have any maintenance cost. Handling MCB is quite safer and it quickly restores the supply.When it comes to house applications, MCB is the most preferred choice for overload and short circuit protection. The MCB is an electromechanical device which guards the electric wires &electrical load from overcurrent so as to avoid any kind of fire or electrical hazards. However, fuse may sense these conditions but it has to be replaced though MCB can be reset. It automatically switches OFF electrical circuit during any abnormal condition in the electrical network such as overload & short circuitconditions. MCB stands for Miniature Circuit Breaker.
Before knowing about the difference among all, let’s get to know about them a little bit. MCB, MCCB, RCCB, and ELCB are circuit breakers but all of them are designed for serving a specific purpose.
