Designed for solar rooftop fire protection, the BFS-S Series fire safety switch offers a string-level load break disconnect solution.
The BFS-S Series FireFighter Safety Switch is a DC disconnect solution for solar rooftop fire protection.
Provide DC power mechanical and complete isolation in the event of a fault. Make a safe area and operating space to protect the firefighter from DC electric shock.
BFS-S offers a variety of disconnect methods. Remove the high DC voltage in PV strings and avoid the risk of electrocution.
