VA51-39 Automatic Circuit Breakers for Reliable Power Protection

Automatic circuit breakers series VA51-39 are designed to carry current in normal mode and current disconnection at short circuits, overloads and inadmissible voltage drops, as well as for infrequent (up to 6 times a day) 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 and 60 Hz and up to 440 V DC. Circuit breakers series VA51-39 have:
- warranty period of 5 years due to the reliability of the design and 100% output control;
- service life of 15 years due to increased wear resistance (16000 mechanical cycles, 2000 electrical cycles);
- reduced power consumption of the circuit breaker to the guaranteed 150 W/h, which saves up to 6500 kW over 15 years of operation;
- environmental friendliness of the products is confirmed by the absence of the use of substances hazardous to human health and the environment.
