Automatic switch A

Automatic switch A, A 160, 200, 250A. Phone Kharkov: +38-067-997-27-74
Technical description: circuit breakers A rated current up to 250 a with a semiconductor, thermal and electromagnetic trips. Circuit breakers A, A, A, A - 2 pole made on the DC and AC (50 Hz, 400) currents. Circuit breakers A, A, A, A - 3 pole, made in alternating current (50 Hz, 400).
Circuit breakers are designed to conduct current in normal mode and at overloads of inadmissible duration, short-circuit and inadmissible voltage reductions, and also for infrequent, up to 30 times a day, operational outages of electric circuits with rated voltage up to 660 V AC frequency 50 and 60 Hz and up to 440 VDC. Circuit breakers AC can also be used to protect and infrequent direct launches asynchronous motors in the category of use AC-3. Circuit breakers are manufactured with semiconductor devices, semiconductor and electromagnetic maximum breakers with thermal and electromagnetic maximum tripping current, only with solenoid maximum tripping current and without maximum tripping current. Circuit breakers can be equipped with breakers zero voltage, independent release, free contacts and an electromagnetic drive. Circuit breakers are available in a fixed version - front, rear and combined attach and pull-out performance.
