The CNC YCM7-125 100A MCCB is a robust molded case circuit breaker engineered for efficient protection of three-phase electrical systems. Designed for AC distribution networks, this breaker ensures safe and stable operation by protecting circuits against overloads, short circuits, and electrical faults.
With a rated current of 100A and support for up to 400V AC systems, it is suitable for industrial panels, commercial buildings, and large residential installations. Its 4-pole configuration provides complete protection across all phases and neutral, ensuring enhanced system safety and reliability.
The breaker features a high short-circuit breaking capacity (around 15kA), allowing it to quickly interrupt fault currents and minimize damage to connected equipment. Its thermal-magnetic trip mechanism ensures accurate and fast response during abnormal conditions.
Built according to IEC 60947-2 standards, the CNC YCM7-125 offers consistent performance and durability in demanding environments. Its compact design supports flexible installation (vertical or horizontal), making it ideal for modern distribution panels.
Whether used in factories, solar distribution systems, or commercial setups, this MCCB provides dependable protection and long-term operational efficiency.
