The DS201 series RCBO is a 1P+N in two-modules device for the protection of end user single-phase circuits against overload and short-circuit currents, provides an optimal trade-off between safety and continuity of service, thanks to the resistance to unwanted trippings, protection against indirect contacts and additional protection against direct contacts (with sensitivity = 30 mA), protection and isolation of resistive and inductive loads. This product is suitable for installations where neutral on the left is needed.
