Ndle2 (NFIN) Residual Current Operated Circuit-Breakers (RCCBS)

Model NO.: NDLE2(NFIN) Operation: Electric Type Arc-extinguishing Medium: Oil-immersed Type Structure: ELCB Type: Circuit Breaker Certification: ISO9001-2000, CE Origin: Wenzhou, Zhejiang Breaking Capacity: Low Voltage Circuit Breakers Speed: Normal Type Circuit Breaker Installation: Fixed Poles Number: 4 Function: Overcurrent Protection Trademark: onandoff or oem HS Code: 8536200000 NDLE2(NFIN)Residual Current operated Circuit-Breakers (RCCBS) Application
The Residual Current operated Circuit-Breakers (RCCBs) 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.
