Product Overview
The Photovoltaic Firefighter Safety Switch is designed to meet the fire safety requirements of photovoltaic (PV) systems. In emergency situations, it quickly isolates and disconnects the photovoltaic DC power supply, thereby ensuring the safety of the photovoltaic power generation system. It is suitable for both residential and commercial and industrial photovoltaic power generation systems, with a circuit voltage as high as 1500V, meeting the requirements of high-power photovoltaic power generation systems.
Over-Temperature Protection: The switch automatically disconnects when the internal temperature exceeds 85°C.
Maximum Circuit Voltage: DC 1500V
Maximum Circuit Current: 40A
Protection Rating: IP65
Material: Flame-retardant V-0 / UV-resistant material
Emergency Shutdown: Pressing the emergency switch during an emergency safely isolates and disconnects the photovoltaic DC power supply. The product is plug-and-play, making installation convenient.
Durability: The product is designed to withstand high temperatures, corrosion, and impacts, ensuring safety and reliability.
Applications: Suitable for residential, commercial, and industrial photovoltaic power generation systems.
