MCB 32A 10kA 4 Pole Type B

Miniature circuit breakers (MCB's) trip if there is an electrical fault caused by either overload or short circuit. B curve breakers trip between 3-5 times rated current in a short circuit situation. B curve MCBs should be applied where loads are resistive and do not have in-rush current. The ideal application is lighting or electronic circuits. Fault tripping indication in the Visi-trip window is given by a red mechanical indicator on the front face. Important to note: MCBs do not protect against electrical shock caused by earth leakage.
