BA57-35M is a series of circuit breakers for currents from 16 to 250 A, with rated voltage up to 690 V AC and 440 V DC, with ultimate breaking capacity up to 42 kA (at 400 V). It has versions with thermal and/or electromagnetic release adjustment, without thermal release.
They are used in industry and at facilities with the requirement of reliable operation in emergency modes and ensuring the safety of operating personnel and protected equipment - due to high characteristics Icu up to 42 kA, operating breaking capacity Ics=100%Icu and increased electrical insulation properties Ui 800 V and Uimp 8 kV.
VA57-35M series circuit breakers:
- 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 (10000 mechanical cycles, 2600 electrical cycles);
- reliability is assessed by the probability of failure-free operation during switching operations.
