Description:
F7-1 series residual current circuit breaker (rccb,elcb,circuit breaker,breaker) adapted to domestic ,public, and industry field are used in the distribution systems TT, TN, and IT, in accordance with the rules and regulations in force. The Residual Current Circuit Breaker RCCB together with the earthing system are therefore used to protect people in case of indirect contacts. These device characterized by a rated residual differential current of 30mA also assure an additional protection in case of direct contacts ,In case of direct contacts ,In addition to the function of protection against direct or indirect contacts ,the residual current circuit breaker(RCCB) incorporate a protective function against the danger of fire in the event of insulation breakdown .comply with standards of IEC 1008:1990,BS 4293.
Applications:
1) F7-1 series residual current circuit breaker is applying to the circuit of AC 50/60 Hz,230V single phase,400V three phases or below it for industrial and mining enterprise , trade building ,commerce and family.
2) F7-1 series residual current circuit breaker is mainly used for preventing electric fire and personal casual accident caused by personal electric shock or leakage of electrified wire net, this is a current operated, fast leakage protector of pure electromagnetic type, which can break off fault circuit rapidly in order to avoid occurrence of accident.
