Face to nearest conductive surface Mounting Rail 2 in. 11 kg A single pole single. Arc chute design.
Arc Chute Design, Insulated fin arc chutes use non conductive plates that are used to stretch the path the arc takes to make it longer and therefore making cooling and dissipation of the arc easier. Each breaker compartment is vented to allow ionized. Use for shock absurd in MCB. Metal plates are generally made of steel because of their ferromagnetic property that helps to attract the arc and keep it inside the stack.
