Each pole has its own enclosure to increase availability and safety.

MCB (Miniature Circuit Breaker) - Electrical Technology

What is Miniature Circuit Breaker (MCB)? An MCB or miniature circuit breaker is an electromagnetic device that eodies complete enclosure in a molded insulating material. The main function of an MCB is to switch the circuit, i.e., to open the circuit (which has been connected to it) automatically when the current passing through it (MCB) exceeds the value for which it is set.
