The circuit breaker is suitable for 12 kV power distribution systems and is widely used in power distribution fields such as power plants, power grids, metallurgy, petrochemicals, and urban infrastructure construction.
Core features
Rated currents up to 5000 A, short-term withstand currents up to 50 kA / 1 s, mechanical service life up to 30,000 cycles;
Eaton's original transmission module is used for reliable closing, low impact force, convenient maintenance and long mechanical service life.
It adopts ultra-low resistance vacuum interrupter and solid sealing pole design, and the insulation performance is reliable;
The conductive elements of the main circuit are silver-plated, with lower contact resistance and better conductivity;
The use of convection flow flow technology, combined with low-resistance arc extinguisher, greatly reduces power loss;
It adopts a new type of oil-free self-lubricating bearing design, which is maintenance-free;
Advanced surface treatment and lubrication technology are used to improve the anti-rust ability, and it is fully applicable to hot and humid areas;
The design of oil buffer and cam curve is adopted to effectively improve the technical performance and prolong the service life.
