ABB group is a leader in manufacturing of different types of electrical equipment. One of the groups is circuit breakers. The producer offers three main categories of them according to level of voltage: low-voltage (less than 1000 V), medium-voltage (up to 36000 V) and high voltage (more than 36 kV).
What about medium voltage circuit breakers ABB Company offers three of them.
Outdoor circuit breakers. The main achievements of this group are gas and vacuum circuit breakers.
Railway circuit breakers. There are models both for indoor and outside installation with single- or two-poles.
Indoor circuit breakers. The most widespread and numerous group. It includes 9 models, mostly vacuum circuit breakers, depends on voltage values. They have IEC or ANSI standards and aimed for generators and transformers, for switching of short-circuit currents, ripple control systems and capacitors, motors, overhead lines and cables (under load and no load). Characteristics of networks is up to 63kA, 3150 A and 40,5kV.
Besides vacuum indoor circuit breakers the ABB offers SF6 gas circuit breakers which do not generate operating overvoltages.
The ABB Company provides complete technical and engineering support and aim to satisfy all needs of its customers in reliable and safe equipment.
