Fire Safety Switch for Photovoltaic Installation FOX S-BOX Plus. This innovative product from FoxESS perfectly complies with unified firefighting procedures used worldwide. Its main task is the automatic disconnection of the DC circuit in the event of fire or power grid failure, preventing voltage from remaining in the solar cables running through the building. Thanks to its AC power supply, the S-BOX Plus enables effortless voltage shutdown at the building’s main distribution board, which results in the automatic disconnection of direct current from the inverter. This mechanism ensures that in the event of any anomaly, the solar cables are not live, which increases safety levels.
The FOX S-BOX Plus fire safety switch is a reliable solution that allows quick response in emergency situations. Additionally, after AC power is restored, the DC circuit is automatically reconnected, making the S-BOX Plus easy to operate and extremely functional.
