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, short-circuit and earth leakage protection, 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.

Key Installation & Operating Instructions

1. Montado em trilho DIN padrão de 35mm
2. Operating temperature range: -25°C a +40°C
3. Grau de poluição: 3
4. Rated impulse withstand voltage (Um): 6kV
5. Wiring capacity: máx.. 25mm² cable

A9F18216 is a commonly used 2P 16A Type C MCB from Schneider’s Acti9 series, offering reliable overload and short-circuit protection. If earth leakage protection is required, a corresponding residual current module must be added, or an RCBO from the iC65N Vigi+ series (por exemplo, A9D11216) can be selected directly.
