3P+N Type B 30mA

RCBOs type B grant protection to persons and machineries in presence of DC current and high frequency AC fault current. Among the several types of RCBOs, type B provide the upmost level of protection.
Some applications’ examples are: electrical installations protecting elevators, escalators, welding machines, electro-medicals’ instrumentation, ventilation systems, PV systems, e-mobility charging stations.

Technical Information

RCBOs’ 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) and with a green led signaling that the voltage is sufficient for product’s functioning as type B.
All products must be power supplied from the power side. Furthermore “cage” type terminals facilitate connection both through conductors (up to 35 mm² rigid and 25mm² flexible) and through busbars (both pin or fork types).

The new CLEM range of RCBOs 3P+N type B is in just four and a half DIN modules, thus granting the maximum protection level in the most compact space.
