VCB stands for Vacuum Circuit Breaker, which is a type of circuit breaker that uses vacuum as the arc quenching medium.

• VCB is used to interrupt the current flow in a circuit by creating a gap between contacts where the arc is extinguished in a vacuum.

• It is commonly used in medium voltage power systems for its high reliability and low maintenance requirements.

• VCBs are preferred over other types of circuit breakers in ap...read more

Ohm is the unit of electrical resistance in the International System of Units (SI).

• Ohm is represented by the symbol Ω.

• It is named after German physicist Georg Simon Ohm.

• One ohm is equal to the resistance of a conductor in which a current of one ampere is produced by a potential difference of one volt.

MCB working principle is to automatically switch off the electrical circuit during abnormal conditions like overload or short circuit.

• MCB detects abnormal conditions like overload or short circuit

• When abnormal condition is detected, MCB trips and disconnects the circuit

• MCB can be manually reset after tripping

• MCB provides protection to electrical circuits and appliances

MCCB stands for Molded Case Circuit Breaker.

• MCCB is a type of circuit breaker that is enclosed in a molded case.

• It is designed to protect electrical circuits from overloads and short circuits.

• MCCBs are commonly used in industrial and commercial applications.

• Examples of MCCB brands include Siemens, Schneider Electric, and ABB.

A motor is a device that converts electrical energy into mechanical energy to produce motion.

• Motors are commonly used in various applications such as industrial machinery, household appliances, and vehicles.

• There are different types of motors including AC motors, DC motors, and servo motors.

• Motors consist of a rotor, stator, and various components such as coils, magnets, and brushes.
