Circuit breakers series VA50-41 for rated currents from 250 A to 1000 A with rated voltage up to 660V AC

Automatic circuit breakers series VA50-41 for rated currents from 250 A to 1000 A at rated voltage up to 660 V AC 50 and 60 Hz and DC up to 440 V, current-limiting (category of application A), selective (category of application B) with electromagnetic and electronic release, without maximum current release. Switches are designed for operation in electrical installations with voltage up to 660 V AC of 50 and 60 Hz frequency and up to 440 V DC for infrequent (up to 6 times a day) operational switching on and switching off of electrical circuits, as well as for protection of electrical equipment from overloads and short circuits.
- warranty period 5 years;
- service life 15 years;
- reliability is assessed by probability of failure-free operation when performing switching operations at load currents and without load currents, as well as when performing protective functions.
