ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC A9N18374 - Miniature Circuit Breaker
The SCHNEIDER ELECTRIC A9N18374 is a single-pole Miniature Circuit Breaker (MCB) from the Acti 9 iC60N series, engineered for overcurrent and short-circuit protection in industrial and commercial electrical distribution systems. This device integrates thermal-magnetic trip technology to safeguard circuits against overload conditions and instantaneous short-circuit faults, ensuring operational continuity and equipment integrity in low-voltage installations. It is designed for modular integration within control panels and distribution boards.
