1250A 3P MCCB with Electric Operator

An intelligent protection and control unit designed for modern power management

At present, in the main power distribution systems of modern large industrial plants, data centers, commercial complexes and new energy power stations, the requirements for core circuit breakers are getting higher and higher. The 1250A 3P MCCB with Electric Operator is precisely a product designed to meet this demand.

Core advantage

1. Ultra-high breaking capacity: It features an extremely high ultimate breaking capacity (such as 65kA and above), capable of handling potential short-circuit current impacts in large-scale power distribution systems with ease, providing a solid safety barrier for the entire downstream network.
2. Selective protection: Equipped with adjustable electronic trip units or high-performance thermal magnetic trip units, it can achieve precise overload long-delay, short-circuit short-delay and instantaneous protection, ensuring selective tripping in case of faults and minimizing the power outage range to the greatest extent.
3. Support for automatic switching logic: It can be easily connected to dual power conversion (ATS) systems, backup generator set self-switching systems or energy management systems, and automatically switch power sources according to preset logic to ensure power supply continuity.

FAQ

Q:What's the difference between "electric operation" and "external electric operation"? Why choose the built-in type?

A:The built-in electric operating mechanism is designed in an integrated manner with the circuit breaker body and tested simultaneously. It has a more compact structure, and its action coordination and reliability are far superior to those of the later externally attached separated electric mechanism. It responds faster and maintains a unified interface, making it the top choice for high-end and reliability requirements scenarios.
