This eRB6/M device is an electronic residual current protection unit with integrated overload protection (RCBO), which functions are depending on the mains voltage. These electronic combined RCD/MCB circuit-breakers - which are especially designed for applications in British Standard distribution systems - are available with rated currents from 6 to 45 A and in tripping characteristic B or C. The switching capacity is 6 kA (eRB6) or 10 kA (eRBM).
The eRB6 RCD/MCB combination switch is available as a type AC surge current proof up to 250 A and has a permanently connected neutral conductor (l = 600 or 300 mm).
The eRBM RCD/MCB combination switch is available as an AC and pulse current-sensitive "standard type" A. The RCBO is available with two characteristics: B and C. It is impulse current resistant up to 250 A.
