Remotely operated circuit breakers А series
TУ 16-522.153-81
Remotely operated circuit breakers are intended:
- for protection of equipment during overload in DC path;
- for switching of electrical circuits: DC and AC (frequency from 400 to 1000 Hz) - А-0,5P, А-0,5М, А-1P, А-1М, А-2P, А-2М, А-14P, А-14М, А-25P, А-25М, А-35PА, А-35МА, А-50PА, А-50МА; DC - А-5P, А-5М, А-5VP, А-5VМ, А-7,5P, А-7,5М, А-7,5VP, А-7,5VМ, А-10P, А-10М, А-10VP, А-10VМ, А-35P, А-35М, А-35VP, А-35VМ, А-50P, А-50М, А-50VP, А-50VМ;
- for automatic disconnection of equipment if operating voltage is simultaneously present on the windings closing and opening coils.
