Key features

Separates breaker, busbar, cable and instrument compartments with metal plates, containing faults within single room to prevent cascading accidents and protect maintenance personnel.

Circuit breaker is installed on a removable truck, realizing clear visible isolation gap; faulty breaker can be replaced in 10 minutes without powering off the whole busbar.

Built-in mechanical + electrical dual interlock system, absolutely preventing wrong closing/opening, live cable connection, ground closing with power on and other fatal misoperations.

Top and rear dedicated pressure relief channels automatically open within 15ms during arc fault, directing hot gas upwards to avoid cabinet explosion and personal injury.

Patented spring energy storage structure reduces handcart operating force by 65%, enabling one-handed operation of 1250A-3150A breakers.

Aviation-grade plug-and-play secondary terminal eliminates screw wiring; handcart replacement time is shortened from 30 minutes to 3 minutes.

Built-in fiber optic temperature sensors on all busbar connections, continuously monitoring temperature rise and sending early alarms before overheating occurs, eliminating hidden fire hazards.

All components can be maintained from the front, no need to leave rear operation space; cabinet depth is reduced by 20%, saving valuable power room space.

Reinforced frame and tinned copper busbar can withstand 31.5kA peak short-circuit current for 4 seconds without deformation, 30% higher than industry average.

The handcart operating mechanism has passed 10,000 times life test without failure, 2 times the national standard requirement, ensuring long-term reliable operation.
