1000V Firefighter Safety Switch

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 1000V, meeting the requirements of high-power photovoltaic power generation systems.

Product Features

Over-Temperature Protection: The 1000V Firefighter Safety Switch automatically disconnects when the internal temperature exceeds 85°C.

Maximum Circuit Voltage: DC 1000V  

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.

Technical Specifications

Application scenarios

1. 1000V Firefighter Safety Switches are deployed on low-rise commercial rooftops where the NEC 690.12 fire-code mandate must be met without adding module-level power electronics.  

2. In agricultural greenhouses rated 20-30 kW, the devices let first responders isolate every string from a single 24 V DC controller mounted at ground level, eliminating DC arc risk while crops remain undisturbed.  

3. Ground-mounted car-port strings feeding a 1000 V central inverter use the RSD to provide rapid-shutdown initiation over the existing DC homerun, saving the cost of additional communication wiring.  

4. Retrofit projects that upgrade older 600 V systems to 1000 V benefit from the same footprint: installers replace only the manual switch with the string-level RSD and reuse the original DC cables and inverter.  

5. Industrial warehouse roofs with long east-west split arrays rely on 1-to-2 string controllers (SYFS-PMSC-80K) to drive up to 100 RSD units, ensuring full-array shutdown within 30 s when the emergency button is pressed at the main service entrance.
