ABB DS201-DS202C New residual current circuit-breakers with overcurrent protection (RCBOs)

ABB DS201-DS202C New residual current circuit-breakers with overcurrent protection (RCBOs)

The ABB DS201 - DS202C series are new residual current operated circuit breakers (RCBOs) that combine overload protection with residual current protection to provide complete and reliable protection for circuits. Designed to meet the demanding needs of modern equipment and plants, they are an integral part of the ABB System pro M compact® system. Designed to comply with EN60715 standards, they can be easily mounted on 35mm DIN rails and play a key role in the safe operation of circuits in all types of electrical systems.

To meet the demand for devices capable of realising complete protection of circuits modern plants, ABB expands the offering of its System pro M compact® with new residual current circuit-breakers with overcurrent protection, both available in two modules DS201 (1 phase + neutral) and DS202C (2 phases).

The new residual current circuit-breakers with overcurrent protection are a technologically advanced and comprehensive range, as concerns size, tripping characteristics, breaking capacity and accessories. 

The new RCBOs are integrated in the System pro M compact® range, with the identical profile that lends a coordinated and streamlined look to the installation.

Intelligent innovation 

Safe and integrated technological products

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.

The DS202C series combines protection against earth-fault current and overcurrent in a single device, guaranteeing high breaking capacities (6 kA with DS202C and 10 kA with DS202C M), in compliance with the IEC/EN 61009 standard. 

With just two modules the DS202C range meets all protection needs, offering choice between 2 different characteristics (B and C) and, for each of these, among 7 rated currents (6, 10, 13, 16, 20, 25, and 32 A). B characteristic allows the protection of very long lines, such as those of the single phase terminal circuits.

All the DS202C devices are type A, for alternating current and/or pulsating current with DC components, suitable for installations with loads manufactured with electronic devices for rectifying current or choking of voltage and current (speed, time, light intensity, etc.). 

The DS202C offering also includes the APR version, with higher protection against 

unwanted trippings due to surge generated, for instance, by lightning, operations on the distribution networks, disturbances, etc

All the devices of the DS201 and DS202C series have been tested up to -25 °C, as indicated by the symbol marked on the front side. On the front of the device the marking also carries the 15-digit ABB code to identify the product after installation, in case of replacement and for any other needs. 

To ensure readability over time, the codes are laser-printed on the devices. 

This also makes them immediately recognizable after they have been removed from their packing.

Common profile for the whole range and easier installation

The new residual current circuit-breakers with overcurrent protection, due to their shape and dimensions, are perfectly integrated with the MCBs of the System pro M compact® family, which they share the wide range of accessories available and the terminal positions with, allowing considerable time savings in wiring operations.

Clear indications to identify and react to any event

The signalling of the internal contact position allows an exact information of the circuit-breaker status: “green”, open contacts; “red”, closed contacts, independently of the toggle position. 

Any earth fault can be immediately identified through the blue indicator, that signals the differential tripping and which cannot be activated in case of manual operation on the toggle. 

This prevents any misinterpretations of the device and system status.

Label carrier for clear and reliable identification Increasingly complex systems require easier identification of the sections corresponding to each single circuit-breaker installed in the switchboard. 

With the practical label carrier fitted in the new circuit breakers you can give maximum visibility to the information relating to the protected loads.

Standardized accessories for the whole range

The DS201 and DS202C series share the wide range of accessories available, such as signalling contacts, auxiliary contacts, shunt trips, undervoltage releases, plug-in base 

and motor device, with the whole range of System pro M compact®

Small size for great usability

The DS202C series (the letter C stands for “compact”) has two poles protected in only 2 modules and breaking capacity (Icn) up to 10 kA. The new range can meet every market requirements for this kind of devices, reducing the space needed in the switchboards
