Technical description: Automatic circuit breakers АВМ20Н are manufactured by electromagnetic releases and releases for tripping from overload. Automatic switches AVM20N 2 poles are made on a direct current. Automatic switches АВМ20Н 3х polar, are made on an alternating current. АВМ20Н - circuit breakers (with a delay of operation on time)

AVM20N automatic circuit breakers are designed to conduct current in normal mode and to protect against overloads of unacceptable duration, short circuits and unacceptable voltage drops, as well as for infrequent, up to 20 times a day, operational tripping 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 a minimum voltage release, an independent release, free contacts and an electromagnetic drive. Automatic are produced in a stationary version - front, rear and combined connection and in retractable design.

Technical characteristics of AVM20NV circuit breakers:

1. Rated current 2000A.

2. Number of poles 2; 3.

3. Rated current of the releases from overload - up to 2000A.

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 of operation of electromagnetic maximum current releases up to 12500A.

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 - up to 161 kg.
