Acti9 C120L-S miniature circuit breakers are designed for high-power load applications, providing high-current load protection and control, overload and short-circuit protection for distribution circuits, as well as manual switching and isolation functions. They can be used with Vigi C120 residual current protection accessories.
Acti9 C120L-S miniature circuit breakers are modular low-voltage protection devices designed for high-power load applications.
The products provide high-current load protection and control, distribution circuit overload protection, short-circuit protection, as well as manual switching and isolation functions. They can be used together with Vigi C120 residual current protection accessories to provide enhanced protection capabilities for low-voltage distribution systems.
Acti9 C120L-S supports C curve and D curve tripping characteristics, with a rated current range of 63A~125A. The rated operating voltage reaches up to 400V AC, and the rated breaking capacity reaches 15000A, making it suitable for commercial buildings, industrial distribution systems and high-load terminal circuits.
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 C120L-S complies with GB10963.1 and IEC60898-1 standards, providing a reliable protection solution for high-load low-voltage distribution systems.
