Circuit breaker A3777P

Automatic switches А3777П 160A are used in ground mobile installations for carrying out of a current in a normal mode, for infrequent (up to 30 times a day) operational inclusions and switching-off of electric circuits by a voltage of 380V or 660V AC of frequency 50 and 400Hz. A3777P - not automatic switches (switches) in fact. There are no thermal and electromagnetic releases in them!

Circuit breaker A3777P are produced in a stationary version, two pole.

Switches can be equipped with an independent release, free contacts, electromagnetic drive, manual remote drive.

The main technical characteristics of the switches:

1. Rated current, A 160.

2. Application category V.

3. Rated currents of thermal releases (RT), A: -.

4. Adjustable rated operating currents IR, A: -

5. Initial operating current in the zone of the overload currents, multiples of the rated operational current of the RP.

6. Setpoint according to the response time in the zone of overcurrent currents -

7. Settings for the response time in the zone of short-circuit currents-

8. Settings for the pickup current in the zone of short-circuit currents A: -.

9. Rated short-time withstand current, kA 5.

10. Rated operating short-circuit breaking capacity, kA 7.5.

11. Wear resistance of switches:

a) the total number of cycles is 16,000.

b) number of cycles of VO under load:

     - switches for rated current 80 A 10000.

     - switches for rated current 160 A 8000.

12. Overall dimensions (width x height x depth), mm 112x260x157.

13. Weight (stationary version), not more, 4.7 kg. With an electromagnetic drive - 6,7 kg.
