TECHNICAL DESCRIPTION: Circuit-breakers A3725, VA3725B, VA3725BHL3, A3725, A3725BR, A3725BUZ, A3725BT3, A3725F are designed for conducting current in normal mode and protection during overloads of unacceptable duration, short circuits and unacceptable voltage drops, and also infrequent (up to 30 times per day) of operational outages of electrical circuits with a rated voltage of up to 660 VAC at 50 and 60 Hz and up to 440 VDC.

Alternating current circuit-breakers can also be used for protection and infrequent direct starting of induction motors in the category of AC-3 applications.

Switches are manufactured with thermal and electromagnetic maximum current releases, only with electromagnetic maximum current releases and without maximum current releases.

Switches can be equipped with an independent release, a zero-voltage release, free contacts and an electromagnetic drive.

Switches are manufactured in stationary and in retractable designs.

Technical characteristics of the switches:

1. Rated current, A 250.

2. Number of poles 2.

3. Rated currents of thermal releases, A 160; 200; 250.

4. Setting for the initial pick-up current in the zone of the overload currents, a multiple of the rated current of the thermal release 1.15.

5. Settings for the current tripping of electromagnetic maximum current releases, A 2500.

6. Rated operating short-circuit breaking capacity, kA:

- at a rated voltage of 380 V AC 35.

- at a nominal voltage of 660 VAC 19.

- at a nominal voltage of 440 VDC 100.

7. Wear resistance of switches:

- total number of cycles is 16,000.

- the number of cycles of VO under a load of 10000.

8. Overall dimensions (width x height x depth), mm 150 x 320 x 157.

9. Weight (stationary version) 7.5 kg. With electromagnetic drive - 11.6 kg.
