ERS-2/4Series PV Array Level 4 Pole 2 String Firefighter Safety Switch for Solar

The ERS Series Rapid Shutdown Switch (RS Switch) is designed to enhance safety in photovoltaic systems. In the event of a fire, firefighters can remotely disconnect the AC power before proceeding with extinguishing, while the built-in DC isolation switch automatically disengages upon detecting a grid signal. This ensures fast and reliable system shutdown.
