Specifications and Parameters

 Rated Current: 63A, indicating that the maximum current that this MCB can safely carry is 63 amps.

 Rated Voltage: The rated voltage of the MCB may vary depending on the application and requirements, but it is usually suitable for circuits with AC 50/60Hz and rated voltage of 230/400V.

 Number of Poles: The number of poles of MCBs may vary from model to model, and the common ones are single-pole (1P), double-pole (2P), three-pole (3P) and four-pole (4P). Among them, 4P indicates that this MCB is used for three-phase + N-wire circuits.

Applications

 Household Circuit: It is suitable for the circuit protection of household electrical equipment, such as lighting, sockets and so on.

 Commercial buildings: In commercial buildings such as shopping malls and office buildings, 63A MCB can be used to protect electrical equipment with larger loads.

 Industrial: In industrial automation and

 production lines, 63A MCB can be used to protect critical equipment and production line circuits.
