Conexiune automata de rezerva cu si fara comanda

Conexiune automata de rezerva cu si fara comanda de la distanta - Technical characteristics:

- Rated operating voltage: 690V; 50/60Hz
- Rated current: 100-630А
- IP code: IP21
- Surge voltage wear resistance: ≥6 000V

Mounting: vertically on a flat surface using bolts

Advantages:
- Selection between device with integrated and separated controller
- Option for setting the change-over time between the two sources - min 3s
- Option for automatic switch-over to the main power supply source after restoring its parameters
- High reliability, safety and long life

Functions:
- Provide continuous power supply and two electrical sources automatic switch in case of failure or deviation from the set parameters
- Control the status of the circuit parameters:
presence of the three phases
limits of the phase voltage
overload
short circuit at the output
- Switching to dual power change-over at power supply phase lack
- Breaking of electrical circuits and control of powerful consumers
- Main breaker in housing or industrial distributing installations supplied with a generator or with a second power supply source

Applications:
- Administrative and public buildings-hospitals, military sites, control rooms
- Industry-productions requiring continuity of the process
- Generators
