125A Molded Case Circuit Breaker Breaks Through Strongly
Ultimate Short-Circuit Breaking Capacity ICUup to 65kA: In the event of a short-circuit fault, it safely interrupts fault currents as high as 65kA. This effectively protects downstream equipment, prevents accident escalation, and provides a top-tier safety barrier for the entire distribution system.
Service Short-Circuit Breaking Capacity ICS up to 50kA: After interrupting a major short-circuit current, the breaker can continue to operate reliably without the need for replacement or maintenance. This ensures power supply continuity and system stability, significantly reducing downtime losses.
TÜV Certification – Internationally Recognized Authority: The CSDM7-125 MCCB has obtained TÜV certification, complying with rigorous international safety standards. This not only guarantees product quality but also signifies that its safety performance is endorsed by a globally authoritative institution, providing strong support for clients’ export projects and global applications.
Fully Automated Production Line for Reliable Performance and Long Service Life: W9 Group’s factory utilizes advanced intelligent production lines to ensure high consistency, precision, and efficiency throughout the manufacturing process, eliminating human operational errors at the source. With 100% automated testing using specialized equipment, every breaker leaving the factory is guaranteed to meet all requirements for electrical performance, mechanical characteristics, and safety parameters.
Leveraging its high breaking capacity and exceptional reliability, the CSDM7-125 125A Circuit Breaker is widely used in scenarios demanding high levels of power safety and continuity:
Industrial Sector: Serves as the main power protection and isolation switch for motors, fans, pumps, and production lines within main and sub-distribution boards in factories and workshops.
Building Sector: Installed in floor-level and main distribution boards of commercial complexes, hospitals, data centers, schools, and hotels, providing protection for lighting, HVAC systems, sockets, and other critical loads.
Commercial & Civil Construction: Acts as the main incoming switch or critical branch switch in distribution boards for high-rise buildings, large shopping malls, hospitals, and schools, ensuring stable power supply to fire protection systems and essential loads.
Commercial Complexes & Data Centers: Delivers reliable overload and short-circuit protection at main or sub-distribution levels in malls, office buildings, and data centers, guaranteeing uninterrupted critical operations.
Infrastructure: Applied in distribution systems for photovoltaic power stations, charging stations, communication base stations, and water treatment facilities.
Upstream Protection: Functions as upstream protection for downstream Miniature Circuit Breakers (MCBs) or low-current MCCBs within a distribution system, enabling selective coordination and enhancing overall power supply reliability.
