What is a CB (Circuit Breaker), and Why is it Important in an Electrical System?
.jpg)
A CB (circuit breaker) is a critical safety device in an electrical system. Its main functions include:
- Interrupting electrical flow in case of faults like short circuits, overloads, or leakage, protecting people and equipment.
- Ensuring system safety by isolating problematic areas.
Using high-quality CB (circuit breaker) increases system lifespan and minimizes risks such as fire or equipment damage.
What Types of CB (Circuit Breaker) are Available in the Market?
CB (Circuit breaker) are classified into various types based on the following criteria:
1. By Functionality:
- Miniature Circuit Breaker (MCB): Used in household or office systems to protect against overloads and short circuits.
- Residual Current Circuit Breaker (RCCB/RCBO): Detects electrical leakage to prevent electric shocks.
- Molded Case Circuit Breaker (MCCB): Designed for industrial electrical systems, capable of handling higher currents than MCBs.
2. By Phase Type:
- Single-phase Breaker: Suitable for home electrical systems.
- Three-phase Breaker: Used in industrial applications.
