Miniature Circuit Breakers
What is a Miniature Circuit Breakers?
A Miniature Circuit Breaker (MCB) is a small, resettable switch that automatically cuts off electrical current during overloads or short circuits to protect wiring and devices.
It replaces fuses, offers faster response, easier reset, and precise ratings for residential and light commercial use.
What is MVCB in Electrical？
In electrical systems, an MCB, or Miniature Circuit Breaker, is a crucial safety device that protects circuits from overcurrent and short circuits. It automatically trips and interrupts the flow of electricity when it detects an abnormal current condition, preventing damage to the circuit and connected devices.
MCB vs MCCB
MCB (Miniature Circuit Breaker) and MCCB (Molded Case Circuit Breaker) are both types of circuit breakers used to protect electrical circuits from overcurrents.
MCBs are typically used for lower current ratings (generally below 100A), while MCCBs are designed for higher current applications (100A and above). MCBs have fixed trip curves, while MCCBs often offer adjustable trip settings for more flexibility.
