Product Description

MCB (Miniature Circuit Breaker) three pole is an electrical device used for protecting electrical circuits from overloads and short circuits. It is designed to handle three-phase electrical systems commonly found in industrial, commercial, and residential applications. The MCB three pole provides individual circuit protection for each of the three phases.

Frequently Asked Questions (FAQ) :

Q: What is an MCB three pole used for?

A: An MCB three pole is used to protect electrical circuits in three-phase systems. It serves as a safety device that automatically shuts off the power supply when an overload or short circuit occurs, preventing damage to the circuit and electrical equipment.

Q: How does an MCB three pole work?

A: The MCB three pole monitors the electrical current flowing through each of the three phases. If the current exceeds the rated capacity of the MCB or if a short circuit occurs, the internal mechanism of the MCB detects the fault and quickly trips, cutting off the electrical supply to the circuit.

Q: What are the advantages of using an MCB three pole?

A: Using an MCB three pole offers several advantages. It provides individual protection for each of the three phases, ensuring that a fault in one phase does not affect the other phases. MCBs are also quick to respond to faults, providing rapid circuit disconnection to prevent damage. They are compact, easy to install, and can be reset manually after a fault is resolved.

Q: Can an MCB three pole be used in residential applications?

A: Yes, an MCB three pole can be used in residential applications, particularly in three-phase electrical systems. It is commonly used in houses or buildings that require three-phase power supply, such as those with heavy electrical loads or multiple appliances and equipment.
