Detailed Product Description
Application
JY7L Residual Current operated Circuit-Breakers ( RCCB) of the AC type adapted to domestic, public, and industrial fields are used in the distribution systems TT, TN, and IT, in accordance with the rules and regulations in force. The RCCBs together with the earthing system are therefore used to protect people in case of indirect contacts. These devices characterized by a rated residual differential current of 30mA also assure an additional protection in case of direct contacts. In addition to the function of protection against direct or indirect contacts, the residual current operated circuit breakers ( RCCBs ) incorporate a protective function against the danger of fire in the event of insulation breakdown.
Compliance with standards of IEC 1008:1990; BS4293
