SAFETY SWITCHES
THE SHUTDOWN DEVICE OFFERS AN ESSENTIAL LAYER OF PROTECTION BY ALLOWING EMERGENCY RESPONDERS TO REMOTELY AND SAFELY DISCONNECT THE DC CURRENT IN PV INSTALLATIONS… Switchtec offers Telergon’s Firefighter Safety Switch
The Telergon CRS Firefighter Safety Switch, a rapid shutdown device designed to enhance safety in rooftop photovoltaic (PV) installations in the event of a fire or emergency, is now available from Switchtec Ltd. As solar panel installations continue to grow, so does the need for reliable and effective safety solutions. The CRS Firefighter Safety Switch offers an essential layer of protection by allowing emergency responders to remotely and safely disconnect the DC current generated by rooftop solar panels. In the event of a fire, it is critical to isolate PV modules from the rest of the electrical network to prevent electric
shock and ensure safe access for firefighters. The Telergon CRS Safety Switch achieves this by automatically interrupting the DC
hazards and protecting both people and property. Strategically installed close to the solar modules, the Firefighter Safety Switch reduces the risk and maximises protection. Its compact size and ease of installation make it an ideal choice for new installations and retrofit projects alike. www.switchtec.com
circuit when the AC grid connection is lost, typically when the fire service disables the AC power supply to the building. Once the electrical hazard is resolved, the system automatically reconnects to resume normal operation. This smart safety switch combines robust electronics to monitor AC current and perform quick shutdown of the DC circuits, minimising the risk of electrical
