Residual current protection for the energy transition - Photovoltaics

The new DFS 4 PV was specially developed for use in photovoltaic systems and
offers the highest possible protection level. With a PV-optimised short-time delay, the all-current sensitive residual current circuit-breaker is resistant to surge
currents. It thus provides higher system availability due to fewer false trippings.

• meets the normative requirements for fire-hazardous premises
• PV-optimised short-time delay
• also available as FI / LS-combination
• energy-efficient due to low power loss
