With Eaton's Moeller series™ fireman's switches, the sun’s energy can be safely and efficiently harnessed. In the event of a fire, DC voltages of up to 1,000 V often continue to be present on the modules and the cables, even after the inverter has been enabled, making it almost impossible for firefighters to do their job. Fireman’s switches ensure the safety of firefighters by making it possible to disconnect the cables leading from the solar modules to the inverter at the touch of a button, either on site or via the local power utility.
