Residual current breakers with overcurrent protection (RCBOs)

Magnetothermic residual current devices with overcurrent protection

RCBOs combine in a single device the residual current function and the overcurrent protection function typical of MCBs.

RCBOs are tripped by both current leakage to earth and overloads and short-circuits and they are self-protecting up to a maximum short-circuit current value indicated on the label.


RCBOs in the System pro M compact and System pro M ranges:
▪ 1P+N breakers in one module: DS 941

4.5 kA, AC type, C characteristic

▪ Compact 1P+N breakers in two modules: DS201 L, DS201 and DS201 M

4,5 6 and 10 kA, AC and A types, B, C and K characteristics

▪ Compact 2P breakers in two modules: DS202C L, DS202C e DS202C M

4,5 6 and 10 kA, AC and A types, B,and C characteristics

▪ 2P, 3P and 4P breakers: DS200 and DS200 M

6 and 10 kA, AC and A types, B, C and K characteristics

▪ 1P+N electronic breakers in one module: DS 271

10 kA, AC and A types, B,and C characteristics


All breaking capacities comply with Standard IEC/EN 61009.
