ABB circuit breaker series include: Emax 2, Formula, Tmax T, Tmax XT, which can be applied in industrial and offshore applications, traditional and renewable energy power generation systems, as well as buildings, data centers and shopping centers.
ABB vacuum circuit breaker VD4 adopts integral pouring pole, which makes the structure more solid and eliminates the influence of dust and moisture on the external insulation ability of arc extinguishing chamber. At the same time, it adopts EL type operating mechanism, that means modular mechanical operating mechanism with spring energy storage and free tripping. The features together make the circuit breaker simple and convenient to use.
ABB DC circuit breaker uses a magnet to attract the arc, pulling it from the air gap, and extinguishes it. Three types of DC circuit breakers are available: ABB solid state circuit breaker, mechanical DC circuit breaker, hybrid DC circuit breaker combining mechanical switch with solid state switch.
ABB earth leakage circuit breaker assures protection to people and installations against fault current to earth. A large offer for standard instantaneous AC and A types is particularly suitable for installation in domestic applications.
ABB Tmax MCCB circuit breaker series includes Tmax T1, T2, Ts3 and T3. All three sizes are fitted with standard adjustment of the thermal threshold and have new three-pole and four-poles designed and constructed to optimize space in the switchboard and simplify coupling with the circuit breaker.
