VA52-41K Series Automatic Circuit Breakers for Overcurrent Protection and Control

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: <ul> <li>- warranty period of 5 years;</li> <li>service life of 15 years;</li> <li>wear resistance: cycles of HE</li> </ul> mechanical 10000, electrical 2000; <ul> <li>- 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.</li> </ul>
