MCBs - iniature Circuit Breakers 3P+N B curve 4,5kA
MCBs GO range are designed to protect installations from overload and short-circuits. They are equipped with two overcurrent releases which feature two tripping sensitivities: one to thermic factors, for protection from low value fault currents and current overloads; the other to electro-magnetic factors, for protection from high value overcurrents (short circuits) . MCBs B curve are generally used when protecting resistive circuits (loads) and electric apparatus with limited starting currents values. MCBs’ mechanism is trip-free, that is the MCBs can also trip when the lever is held on close position. All products can be power supplied from both the top and the bottom terminals. Furthermore “cage” type terminals facilitate connection both through conductors (up to 35mm² rigid and 25mm² flexible) and through busbars (both pin or fork types).
