Technical description: A3140 circuit-breakers for rated current up to 800 A by with electromagnetic releases and electromag-thermal releases. Circuit-breakers A3144 3-pole, are made on an alternating current.
A3144 circuit breakers are designed to conduct current in normal mode and protect against overloads of unacceptable duration, short circuits and unacceptable voltage drops, as well as for infrequent, up to 20 times a day, operational trips of electrical circuits with a rated voltage of up to 660 V AC frequency 50 and 60 Hz and up to 440 VDC. AC automatic circuit breakers can also be used for protection and infrequent direct starts of asynchronous motors in the application category of AC-3. Circuit-breakers are produced by thermal and electromagnetic maximum releases, only with electromagnetic maximum current releases and without maximum current releases. The circuit breakers can be equipped with an independent release, free contacts and an electromagnetic drive. Automatic are produced in stationary version - with front, rear and combined connection.
Technical characteristics of the switches:
1. Rated current up to 800A.
2. Number of poles 3.
3. Rated currents of thermal releases 250-600A.
4. Setting for the initial pick-up current in the zone of the overload currents, multiples of the rated current of the thermal trip unit 1.3.
5. Settings for the current tripping of electromagnetic maximum current releases up to 4200A.
6. Rated operating short-circuit breaking capacity, kA: at a rated voltage of 380 V AC 25, at a nominal voltage of 660 V AC 19, at a nominal voltage of 440 VDC 50.
7. Wear resistance of circuit breakers - total number of cycles of VO 3000, number of VO cycles under load 1500.
8. Weight (stationary version) - 20.0
