DFS PV – Residual current protection for photovoltaic systems

The new DFS PV has been specially developed for use in photovoltaic systems and offers the highest possible protection level. With a PV-optimised short-time delay, the AC/DC sensitive residual current circuit-breaker is resistant to surge currents. It therefore offers higher system availability due to fewer false tripping events.

·         fulfils the normative requirements for premises at risk of fire

·         PV-optimised short-time delay

·         also available as residual current operated circuit-breaker with integral overcurrent protection (RCBO)

·         energy-efficient due to low power loss
