These residual current circuit-breakers are AC-DC sensitive and provide VDE fire protection requirements for frequencies up to 20 kHz. Our PV RCCBs were specifically developed for use in photovoltaic systems and offer the highest level of protection. Thanks to a PV-optimised short-time delay, the RCCBs are particularly resistant to surge currents. This reduces nuisance tripping and increases your system’s availability. Standard RCCBs are designed for circuits with 230/400 V at 50 Hz. The HD design makes our RCCBs particularly resistant to harmful environmental influences and therefore suitable for harsh environments.

AC/DC sensitive for residual currents with frequencies and mixed frequencies from 0 Hz to 20 kHz, fire protection according to VDE 0100-420, complete functionality with mains voltages from at least 50 V AC on any two active conductors, high short-circuit resistance, ouble-sided double-decker terminals for large conductor cross-section and busbar connection, switching position indicator, multifunction control toggle with three positions: "on", "off", "triggered", any neutral conductor position

quick fastening to mounting rail, any installation position, supply preferably from above

RCCBs of the PV series are suitable for private, commercial and industrial installations with TN-S, TT and TN-C-S systems in which photovoltaic systems are installed.

suitable for use in 50 Hz AC networks, not intended for use on the output side of controlled electrical equipment such as frequency converters
