The 3P 400A-630A MCCB (Molded Case Circuit Breaker) is designed for reliable power distribution protection and motor protection applications. This high-performance circuit breaker features complete protection functions to improve power supply reliability and prevent unnecessary outages.
Key features include compact size, high breaking capacity (25KA), short arcing time, and excellent anti-vibration performance. The breaker can be installed in either vertical or horizontal orientation and includes isolation functionality. Note that wiring must follow specific connection requirements (power line to 1/3/5 terminals, load line to 2/4/6 terminals).
The MCCB utilizes high-quality DMC insulating materials and precision metal components made from high-standard steel, brass, and copper. Available in multiple color options including white, bright grey, dark grey, and black, with flame retardant or non-flame retardant versions.
With an electrical life of 1500 operations and mechanical life of 8500 operations, this durable circuit breaker is ideal for industrial applications in petroleum, chemical, power, building, machinery and metallurgical industries.
Customization options include structural components (static contact, movable contact-piece, clip, holder, operational mechanism) and appearance design (frame color combinations, company branding, certification marks).
