Circuit breakers of VA50-43 series for rated current of 2000 A, for rated voltage up to 660 V of alternating current frequency

Automatic circuit breakers series VA50-43 are designed to carry current in normal mode and disconnect current at short circuits, overloads, as well as for infrequent operational switching on and off of electrical circuits. The series is designed for rated currents of 2000 A, 1600 A. Depending on the type of current and voltage, it has switching capacity up to 135kA.
Circuit breakers series VA50-43:
- warranty period of 5 years;
- service life 15 years due to increased wear resistance (6300 mechanical cycles, 1250 electrical cycles);
- reliability is assessed by the probability of failure-free operation when performing switching operations at load currents and without load currents, as well as when performing protective functions;
- environmental friendliness of the products is confirmed by the absence of hazardous substances for human health and environment. All products have a declaration of TR TS 037/2016.
