Product Description 
The Sun Provides Energy, Slocable Provides Safety
In most photovoltaic systems, theDC isolator is integrated into the DC/AC power inverter. After switching off the DC isolator, the ables between the solar modules and the inverter running through the building are still subject to up to 1000V DC.
In the event of a fire, firefighters are exposed to a very serious source of potential danger.The Slocable Rapid Shutdown Firefighter Safety Switch provides the solution.Rapid Shutdown Device directly disconnects the DC current in close proximity to the solar modules and creates a safer situation for firefighters.
Advantages of Rapid Shutdown Firefighter Safety Switch:
- 1~10 strings available
- Up to 40A
- Up to 1500V DC
- CE certification
- APP remote control
- Motor driven switch disconnection
- High grade PC, IP65 protection &unti UV
- Knock outs丨Cable glands丨MC4 connectors
- Built-in DC isolator with CE,1P65
- Shut down automatically exceeding 80°C
- Rapid Shutdown is equipped with breathing valve to avoid conden-sation inside the enclosure.
- Rapid Shutdown is designed for residential solar installations.
1. AC Power manually shut down
Any firefighter in fighting a fire is to shut down the main AC power circuit at first.This makes it possible to start extinguishing the actual fire without the risk of electrocution. Slocable developed the Rapid Shutdown Devices according to this standard international safety routine. Rapid Shutdown Device prevents firefighters from having to take any extra action in case of a fire, maximizing the safety in the event of a fire.
2. Automatic DC Power Shut Down
As soon as a firefighter shuts down the main AC circuit, the SRS will detect this. If this power down situation lasts, it will automatically switch to the OFF position in 5 seconds. Since the SRS is located close to the PV modules, the high voltage DC current from the PV modules will be completely isolated, which leaves a safe situation for the firefighters by Rapid Shutdown.
