Interruttore differenziale magnetotermico 3P+N
RCBOs 3P+N GO range provide a full protection to both the persons and the electrical appliances, as they are designed to automatically cutoff the power supply in case of overload, short-circuit and earth leakage.
Type AC RCBOs grant protection in presence of fault currents with sinusoidal alternate wave. They are therefore recommended as protection devices of three-phase circuits supplying thermic or electro-mechanical apparatus without or with electronic parts not involving significant wave shape changes.
RCBOs’ functioning is independent from line voltage and its mechanism is trip-free, that is the RCBOs can also trip when the lever is held in ON position.
All RCBOs are equipped with a visual indicator which discriminates residual current tripping (blue) from overload tripping (transparent).
All products can be power supplied from both the top and the bottom terminals. Furthermore “cage” type terminals facilitate connection both through conductors (up to 35mm² rigid and 25mm² flexible) and through busbars (both pin or fork types).
RCBOs 3P+N are in just four DIN modules, thus granting a significant space saving compared to the common solution MCBs + add-on-block.
In addition to B and C characteristic , RCBOs can also be supplied in D curve upon request.
