China Circuit Breaker Manufacturer, Supplier, Factory

1.RCBO is mainly used in AC 50Hz(60Hz), rated voltage 230/400V, rated current 6A to 63A low voltage terminal distribution system. RCBO is equal with MCB+RCD function; It is used for electric shock protection and human indirect contact protection, electric equipment protection when human body touching electricity or electric network leak current exceeds stipulated value,and over load and short circuit protection ; It can also be a non-frequency operator in the circuit, wildly used in the residential and commercial district. It complies with standard of IEC61009-1. 2.MCB is used in AC50/60Hz, rated voltage of 230V3, 4 poles 400V, rated current to 63A for overload and short-circuit protection as well as for unfrequented switching under normal case.It is used extensively for industry, commercial and household.This product conform to IEC60898 standard. 3.RCCB is in conformity with the standards of IEC61008.It can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunkline.Thus it is suitable to avoid the shock hazard and fire caused by earth leakage.It can be used in circuits up to single phase 240V,three phase 415V,50 or 60Hz.

SONTUOEC is one of the Chinese suppliers/manufacturers specializing in the production of various small electrical appliances Electric Moulded Case Circuit Breaker is a kind of electrical equipment with protection functions such as overload, short circuit and under voltage. Its working principle is that under normal operating conditions, the circuit breaker is in a closed state, when the circuit overload, short circuit or under voltage and other faults, the circuit breaker will automatically disconnect the circuit, so as to protect the circuit and the safety of the equipment.

 SONTUOEC is one of the Chinese suppliers/manufacturers specializing in the production of various small electrical appliances STM10-63 Series high breaking miniature circuit breaker has the features of structure advanced, performance reliable, breaking capacity high, appearance elegant and its shell and parts are made of material with impact resistance, strong flame-retardant feature.
