CNC | MCCB-Molded Case Circuit Breaker YCM8 Series


CNC Electric has developed a range of molded case circuit breakers that cater to different current ratings and application requirements as the YCM8 Series which features as:

1. Wide Current Range: The new MCCB series is designed to cover a wide range of current ratings, starting from lower values (e.g., a few amps) to higher values (e.g., several thousand amps). This allows the series to meet diverse application demands, from residential and commercial to industrial settings.

2. Various Frame Sizes: MCCBs are available in different frame sizes to accommodate different current ratings and breaking capacities. The frame size determines the physical dimensions and the maximum current-carrying capacity of the circuit breaker.

3. Adjustable Trip Settings: The new series may offer adjustable trip settings, allowing users to customize the trip levels based on their specific requirements. These settings can include both instantaneous and long-time delay trip levels to provide flexibility in protecting different types of electrical systems.

4. High Breaking Capacity: MCCBs in the new series are designed with a high breaking capacity to effectively interrupt fault currents. The breaking capacity should match or exceed the potential fault current in the electrical system to ensure proper protection.

5. Selectivity and Coordination: The new MCCB series may provide selectivity and coordination features that enable cascading tripping, ensuring that only the circuit breaker closest to the fault trips while the others further upstream remain unaffected. This allows for better fault localization and minimizes downtime.

6. Enhanced Safety Features: The MCCBs in the new series may incorporate enhanced safety features, such as arc flash detection and prevention mechanisms, ground fault protection, and improved insulation capabilities. These features help mitigate risks associated with electrical faults and ensure the safety of personnel and equipment.

MCCBs are essential components in electrical distribution systems as they help prevent electrical overloads and short circuits that can lead to equipment damage, electrical fires, or electrical hazards. They provide a reliable and convenient means of disconnecting power when needed and are widely used in various industries to ensure electrical safety and system reliability
