DESCRIPTION DU PRODUIT
SCHNEIDER ELECTRIC A9F18125 - Miniature Circuit Breaker
The SCHNEIDER ELECTRIC A9F18125 is a 1-pole miniature circuit breaker from the Acti9 iC60N series, engineered for reliable overcurrent and short-circuit protection in low-voltage electrical distribution systems. It integrates a thermal-magnetic tripping mechanism to safeguard circuits against sustained overloads and instantaneous short-circuit events. This device is suitable for deployment in commercial, industrial, and infrastructure applications requiring robust circuit protection.
