Description
Fox Fire Safety DC Isolator for PV - S-Box, 4 strings
Fire safety DC isolator for photovoltaic PV systems for 4MPPT 1500V DC MC4 IP66 Fox-S-Box-4 FoxESS
The FOX-S-BOX FOXESS isolator is a specially designed device intended to ensure safety in photovoltaic installations in the event of failure or fire. It is a DC isolator designed for PV photovoltaic systems with four MPPT at 1500V DC, MC4 and motor-driven connector, with IP66 protection rating.
The main purpose of this isolator is to rapidly disconnect the power supply in hazardous situations, which protects emergency personnel and minimises potential damage. In the event of a fire, there is a risk of dangerous situations related to current flow in the photovoltaic installation, even after the DC current between the inverter and panels has been switched off.
This isolator can be installed on four strings, which further increases its functionality and ability to adapt to specific installation requirements. In a situation where firefighters disconnect the alternating current (AC) before undertaking firefighting operations, the S-box series safety isolator automatically detects the grid failure and switches off the isolation switch, providing an additional layer of safety.
A key feature of this isolator is its location close to the photovoltaic panel, which minimises the risk of serious hazards to firefighting crews and ensures the safety of the photovoltaic system. Thanks to this solution, rapid and effective response in emergency situations is possible, which translates into the protection of people and property.
