protect / Residual current circuit-breakers (RCCBs)

Residual current circuit-breakers, two-pole, 125 A, 0.5 A, Type A, with remote-tripping function, N left or right

Mains voltage-independent residual current circuit-breaker (RCCB) for detecting AC residual currents and pulsating DC residual currents
with an additional signalling contact and terminals switched in parallel to the test key for activating the test device using external switching contacts
doubled wiring level above and below
switch position indicator and multifunction switch toggle with the functions "on", "off" and "tripped" (centre position)
