Tips: How to choose an MCB breaker?

When selecting an MCB (Miniature Circuit Breaker), consider the following factors:

Current Rating: Choose an MCB with a current rating that matches the expected load of the circuit. For example, for a 2 amp load, select a 16A MCB.
Voltage Rating: Ensure the mini circuit breaker is rated for the voltage of your system, typically 230V for residential or 400V for industrial applications.
Breaking Capacity: The micro circuit breaker should have a breaking capacity (the maximum fault current it can safely interrupt) that exceeds the potential short-circuit current in your system.
Trip Curve: MCBs have different trip curves (B, C, D). Curve B is suitable for residential circuits with resistive loads, while C is ideal for circuits with moderate inrush currents like motors.
Number of Poles: Select the number of poles based on your circuit type—single pole for single-phase or multi pole for three-phase systems.
