protect / Residual current circuit-breakers (RCCBs)

Residual current circuit-breakers, four-pole, 40 A, 0.3 A, for heat pumps, N right

is particularly suited for protecting heat pumps and has an HP-optimised slow-blow:

AC/DC sensitive residual current circuit-breakers (RCCBs) for detecting AC residual currents and pulsating and smooth DC residual currents
sensitive to residual currents and mixed frequencies from 0 Hz bis 20 kHz
doubled wiring level above and below
switch position indicator and multifunction switch toggle with the functions "on", "off" and "tripped" (centre position)
viewing window for labels
