Schneider A9F18216

: iC65N 2P C16A Schneider A9F18216 Miniature Circuit Breaker

Primeiro, it should be clarified that A9F18216 is a disjuntor miniatura (MCB) of the iC65N series, not an RCBO (Residual Current Circuit Breaker with Overcurrent protection). An RCBO is an integrated device with overload, proteção contra curto-circuito e fuga à terra, while A9F18216 only provides overload and short-circuit protection. For earth leakage protection, it must be used with an additional Vigi iC60 or QuickVigi iC60 residual current module.
