RCCB/ELCB 2P 40A 300mA AC

A miniature circuit breaker (MCB) is an electromechanical device that can protect electrical circuits from excessive current by automatically stopping the current when it exceeds a certain limit. The Miniature Circuit Breaker (MCB) functions as a circuit breaker, short circuit or short circuit protection, main switch, and safety for excessive loads. The Electric Miniature Circuit Breaker (MCB) works automatically to cut off the electric current when the current passing through it exceeds the nominal current on the Schneider Miniature Circuit Breaker (MCB).

Function of the Miniature Circuit Breaker (MCB):

• Secures cables against overloads and short-circuit currents
• Conducts current without overheating
• Opening and closing a circuit below rated current
• Protection against damage to insulators

Selection of Miniature Circuit Breaker (MCB) Power Breakers

The choice of power termination is determined by several things:

• Standard
• Termination Capacity
• Rated Current
• Voltage
• Number of poles
• Travel Curve Shapes
• Frequency system, and
• Load application
