These residual current circuit-breakers are AC-DC sensitive and provide VDE fire protection requirements for frequencies up to 20 kHz. Our HP RCCBs were specially developed for the protection of heat pumps. They meet all the requirements of leading heat pump manufacturers and provide perfectly tailored protection. Thanks to the HP-optimised short-time delay, system availability is significantly increased – ensuring especially efficient and safe operation of your heat pump. 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 variant HP are suitable for private, commercial and industrial installations with TN-S-, TT- and TN-C-S systems which use heat pumps.

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