Automatic protection and control circuit breaker AZU-400A is designed to protect and control a DC generator and is used for:
- automatic switching on of the generator to the network when the generator voltage exceeds the voltage of the on-board network by 0.2 ... .1 V;
- automatic disconnection of the generator from the mains at a “reverse current” of 15..35 A, as well as in the event of a short circuit in the generator or at its feeder;
- preventing the generator from turning on with wrong polarity;
-alarm about turning on and off the generator;
- issuing a signal to turn on the relay of labeled receivers of electricity.

1. Voltage of the switched circuit and control circuit – 24, .. 29.4V;

2. Rated value of the switched current (current in the contactor contact circuit) – 400A;

3. Overvoltage at which the generator is connected -0.2 … 1V;

4. Trip current (reverse), – 15, .. 35;

5. Voltage of release of contacts of the contactor -9 ± 1V;

6. Consumption current – no more than 0.8A;

7. Operating mode – long-term.
