CCM1 Plastic Case Circuit Breaker

We are delighted to announce the latest expansion of our power distribution portfolio with the introduction of the CCM1-225 Moulded Case Circuit Breaker (MCCB). This new addition is engineered to meet the growing market demand for highly reliable, robust, and precision-engineered circuit protection, making it an indispensable component for modern industrial, commercial, and utility-scale electrical infrastructure. The CCM1-225 is more than just a switch; it is a critical safeguard designed to ensure the stability, safety, and longevity of your entire electrical system.

The defining characteristics of the CCM1-225 lie in its superior technical specifications. Operating at a Rated Current ($I_n$) of 225 A and a Rated Operational Voltage ($U_e$) of AC 400V, this MCCB is perfectly suited for main circuit protection, distribution feeders, and large-scale equipment circuits. What truly sets this device apart is its exceptional short-circuit capability. It boasts a formidable Rated Ultimate Short-Circuit Breaking Capacity ($I_{cu}$) of 50 kA and a Rated Service Short-Circuit Breaking Capacity ($I_{cs}$) of 35 kA at AC 400V. These high ratings ensure that the circuit breaker can safely interrupt extremely large fault currents—a critical necessity in high-power distribution boards—without compromising its structural integrity or the safety of the surrounding equipment. The high $I_{cs}$ value signifies that the breaker can repeatedly perform this interruption without requiring immediate replacement, thereby drastically improving the service continuity and operational uptime.

Designed in accordance with rigorous international standards, including IEC 60947-2 and GB14048.2, the CCM1-225 adheres to the most demanding global safety and performance benchmarks. Its robust moulded case provides superior insulation and mechanical strength, with a high Rated Insulation Voltage ($U_i$) of 800V and a Rated Impulse Withstand Voltage ($U_{imp}$) of 8 kV. This high-level insulation ensures enhanced safety for operators and greater durability against electrical surges and transients prevalent in complex networks. Furthermore, the breaker features a Category A utilization, confirming its suitability for general distribution and protection applications.

The operational mechanism of the CCM1-225 ensures maximum protection against both overload and short-circuit faults. Overload protection is typically provided by a thermal-magnetic trip unit, which acts on the principle of thermal expansion for sustained overcurrents and electromagnetic force for instantaneous short circuits. The presence of a clear ON/OFF/Tripped indicator simplifies fault diagnosis and operational status monitoring, facilitating quick and secure isolation during maintenance or after a fault event. Its compact yet heavy-duty design allows for efficient integration into various switchboards and control cabinets, maximizing panel space utilization without sacrificing performance.

Investing in the CCM1-225 is an investment in unparalleled reliability and safety. Its integration into a system significantly minimizes the risks of fire, equipment damage, and prolonged power outages caused by electrical faults. It serves as a reliable anchor in any high-demand distribution system, guaranteeing dependable performance under the most challenging conditions. We are confident that the CCM1-225 MCCB will become the preferred choice for engineers and panel builders seeking a proven, high-performance solution that adheres to the pinnacle of electrical safety standards. We encourage our partners to explore the detailed specifications and integration possibilities of this powerful new product.
