ABB System proM RCBO DS201 L

Like all electromechanical residual current devices, these new products ensure protection against earth fault currents, both when the power supply of the neutral wire is accidentally interrupted and when, in the 2 phase version, only one phase is present. To make wiring operations easier, the bidirectional cylinder-lift terminals based on innovative technology provide connection, through cables (25 mm2 flexible) or busbars. The DS201 and DS202C series are designed to be easily installed on a 35 mm symmetrical DIN rail, in compliance with the EN 60715 standard.

The DS201 series replaces the actual range of 1P+N RCBOs and combines protection against overcurrent and earth fault current in a single device. The range is available in three versions: DS201 L (with 4,5 kA breaking capacity), DS201 (with 6 kA breaking capacity) and DS201 M (with 10 kA breaking capacity), in compliance with the IEC/EN 61009 standard.

The new range in two modules has 2 different characteristics (B and C), with rated current up to 40 A and meets all the protection requirements of single-phase circuits. K characteristic is also available in the DS201 version (6 kA). The rated sensitivity vary according to version: 10, 30, 100, 300, and 1000 mA. In DS201 and DS201 M the breaking capacity of the protected pole is 6 kA, allowing it to be used in installations where, in case of earth fault, the fault current might reach this value (e.g. in TN network system).

The DS201 offering also includes the APR version, with higher protection against unwanted tripping due to surge generated,
for instance, by lightning, operations on the distribution networks, disturbances, etc.
