VA04-36 Automatic Circuit Breakers for Reliable Protection in Electrical Circuits

The switches are designed to carry current in normal mode and disconnect current in short circuits, overloads, as well as for infrequent operational switching on and off of electrical circuits and are designed for operation in electrical installations with rated voltage up to 660 V AC 50, 60 Hz and up to 220 V DC.
- warranty period 5 years;
- service life 15 years;
- 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;
- have, depending on the type of current and voltage, switching capacity up to 40 kA;
- up to 6 000 cycles resource of switching on and off under load depending on the value of nominal current;
- maintain operability in the temperature range from -50 to +55 °? and air humidity up to 98 %.
