FE-125 125 A AC MCB 415V 3P Electrical Circuit Breakers
FE-125 high breaking capacity circuit breaker is used for AC 50/60HZ, single-pole 230V or two, three, four-pole 415V
circuit for protecting the circuit that overload and short circuit may take place. It can be used in lighting and electric motor
distribution system. Mean while it is applicable to an unfrequented switch over the electric apparatus and lighting circuit
under normal condition. Breaking capacity is up to standard of IEC60947-7 10KA.
