Circuit breakers are invaluable devices. They play a significant role in electrical distribution. They effectively protect circuits and equipment from various hazards. These primarily include short circuits, overloads, and ground faults. There are different types of circuit breakers designed for different purposes. This article provides a complete guide to the common types of circuit breakers.

Circuit Breakers: Overview of Different Types

Circuit breakers come in various designs to serve diverse needs. The various types of circuit breakers differ in features like rated voltage and current, tripping characteristics, usage scenarios, and more. Common types include:

1. MCB

Miniature Circuit Breakers are the most popular type. They are ideal for low-power branch circuits. They are suitable to be used in residential and small commercial settings. They have a rated current of 1-125A and are installed in distribution boards or panels. An MCB low voltage circuit breaker trips automatically during overloads or short circuits to isolate faulty circuits and protect wiring. MCBs are economical. They are also easily replaceable if faulty.

2. MCCB

Molded Case Circuit Breakers are robust. They are suitable for medium-voltage industrial circuits. They have higher current ratings of 16-1600A. These types of circuit breakers are commonly seen in large commercial buildings, factories, and infrastructure utilities.

3. RCCB

Residual Current Circuit Breakers detect leakages to the ground through an electrical imbalance. They quickly respond even to small faults and protect users against electric shocks. The current rating is typically 16-100A. RCCBs are ideal for socket circuits, fixed equipment, and wherever personnel safety is critical.

4. RCBO

Residual Current Operated Circuit Breakers combine MCB and RCCB in one device. They offer overload as well as residual current protection simultaneously. RCBOs find extensive application in general household wiring systems, small offices, and various industrial settings. These types of circuit breakers provide cost-effective dual protection.

5. ACB

Air Circuit Breakers use air to interrupt faults. They are suitable for main distribution boards with currents in the 200-7500A range. ACBs have compact designs optimized for switchgear rooms and substations where space is limited. They can isolate faults very quickly with high breaking capacities.

6. MPCB

Motor Protection Circuit Breakers boast high performance and reliability. They integrate the functions of overload relays and circuit breakers and offer protection against short circuits, overloads, and phase imbalances. This ensures motor reliability and safety.
