Projoy Firefighter Safety Switch 10 Pole 5 Strings

The Projoy Firefighter Safety Switch (10 Pole / 5 String) is a smart DC disconnection device designed to instantly isolate the DC power from solar panels in the event of fire, maintenance, or emergency situations. It provides rapid shutdown protection for installers, emergency responders, and property owners — ensuring compliance with fire safety standards and reducing electrical hazards on rooftops.

This advanced isolator automatically disconnects all PV strings when AC power is lost or when triggered by the building’s emergency system. Each unit controls up to five PV strings (10 poles total), making it ideal for commercial and industrial solar PV installations.

Built with high-quality arc-suppression components, flame-retardant housing, and an IP66-rated weatherproof enclosure, the Projoy Firefighter Switch ensures maximum safety, reliability, and long service life.
