FuseBox RTB06B40BD 40A Type B Bidirectional RCBO
40A 2 Pole Type B RCBO with 30mA Protection
The FuseBox RTB06B40BD 40A Type B Bidirectional RCBO is a 40A two-pole protective device from FuseBox’s Type B bidirectional RCBO range. It provides 30mA earth-leakage protection alongside overcurrent and short-circuit protection, with a 6kA prospective fault current rating.
Modern electronic loads can produce residual currents that conventional device types are not intended to detect. This Type B unit is designed to detect AC, pulsed DC and smooth DC residual fault currents. The bidirectional design is particularly relevant where current flow may occur in either direction, such as selected solar, EV charging and other power-electronic applications.

Type B Protection for Modern Electrical Loads
The FuseBox RTB06B40BD 40A Type B Bidirectional RCBO is intended for circuits where the installation design calls for Type B residual-current detection. Because the device detects smooth DC residual currents as well as pulsed DC and AC, it addresses a wider fault-current spectrum than Type A or Type AC devices. The final RCBO type and rating must always be selected to suit the connected equipment and installation design.

Bidirectional 2 Pole Circuit Protection
With its 40A rating, 30mA residual-current sensitivity and 6kA PFC, the FuseBox RTB06B40BD 40A Type B Bidirectional RCBO gives installers a dedicated Type B option within the FuseBox circuit-protection range. Its bidirectional operation supports applications where power flow is not limited to a single direction.
