Acti9 C120H Miniature Circuit Breaker

Acti9 C120H miniature circuit breakers are modular protection devices designed for high-power load applications and low-voltage distribution systems. The products are mainly used for high-current load protection and control, overload protection, short-circuit protection, as well as manual switching and isolation operations. They can be combined with Vigi C120 residual current protection accessories to meet different protection requirements in low-voltage distribution systems. Acti9 C120H supports multiple pole configurations including 1P, 2P, 3P and 4P. The rated current range is 63A~125A. The maximum operating voltage reaches 440V AC, and the rated breaking capacity reaches 10000A, making it suitable for high-load low-voltage distribution applications. The product adopts DIN 35 mm standard rail mounting and supports flexible installation direction from 0° to 360°. The device provides IP20 protection degree, and can reach IP40 when installed in Pragma or Prisma distribution enclosures. Acti9 C120H complies with GB/T10963.1 and IEC/EN60898-1 standards, providing a reliable protection solution for commercial buildings, industrial distribution systems and high-load terminal circuits.
