VA52-41K series circuit breakers for rated currents up to 1000 A with rated voltage from 690 V to 1140 V AC

Automatic circuit breakers series VA52-41K are designed to carry current in normal mode and disconnect current in short circuits, as well as for infrequent operational switching on and off of electrical circuits. This is a series of circuit breakers for currents of 1000 A, with rated voltage up to 1140 V AC, with ultimate breaking capacity up to 15 kA.
According to the method of installation the circuit breakers are of stationary design.
Circuit breakers have:
- warranty period of 5 years;
- service life of 15 years;
- wear resistance: cycles of HE
mechanical 10000, electrical 2000;
- 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.
