ABB DS203NC Residual Current Circuit Breaker
The complete evolution
DS203NC and ABB modular range: absolute integration
ABB is present on the market of electric installations with a range of the most complete and integrated modular DIN rail components. Circuit breakers, control and measurement solutions, devices for energy saving and many more are realized in compliance with the standards to anticipate the application needs of the customers, and are developed and constantly improved to ensure cutting-edge performance. A real “team”, in which it is also involved the family of DS203NC residual current circuit breakers with overcurrent protection. Designed to respect the concept of compatibility that permeates the entire portfolio of ABB modular products, also this line takes account of the growing plant-related constraints and demanding requirements of protection imposed worldwide by new generation installations.
In any application where the dimensions represent a potential barrier, the products of the family of DS203NC residual current circuit breakers with overcurrent protection from ABB guarantee a reliable and complete protection againstovercurrent and earth fault currents.
Characterised by a compact size, equal to a normal 4-pole MCB, the 3P+N RCBO of the line DS203NC are suitable to three-phase circuits installed in environments where space is a precious resource, such as zones for marinas and camping, switchboards for temporary environments such as yards orexhibitions, industrial sockets and power generators. The line focuses on the efficiency of installation, sharing all the functional and mounting characteristics that distinguish the modular devices of the System pro M compact® family. Thanks to this legacy, the DS203NC RCBOs offer a solution of international standing, with a wide set of certifications and the level of quality that only a global and recognized manufacturer as ABB can ensure.
The essential protection
New solutions and retrofit: the importance of versatility
In all electrical installations it is crucial to ensure, at any time and under any condition, the safety of people, facilities and related equipment. Even in applications where space is a limited resource, the quality of protection must be given and guaranteed through features effective and respectful of the standards, without penalizing aspects such as size, ease of installation and flexibility of use.
The DS203NC family of 3P+N residual current circuit breakers with overcurrent protection by ABB has been developed with the aim of meeting requirements such as the protection and safety of people, equipment or facilities, offering a compact solution in 4 modules that is at the top of its category from every point of view. Ideal for the protection of three-phase distribution circuits in commercial facilities, but also of equipment and industrial sockets, the products of the RCBO 3P+N DS203NC family of ABB have all the necessary specifications to ensure reliable and durable performance, offering space savings of 30% comparedto a standard configuration. DS203NC RCBOs are the ideal solution for new installations,ensuring space saving in switchboards, as well as in retrofitting of existing plants, by adding earth fault current protection in installations where it wasn’t foreseen, without any impact on the overall dimensions of the system and on the placing of the existing devices
The compact reliability
DS203NC: increase safety, reduce space
Totally integrated into the modular range System pro M compact®, the DS203NC residual current circuit breakers with overcurrent protection respond to the request for protective equipment that meet the different types of circuits of the modern three phases systems, increasingly compact and sensitive. Thanks to the many types and to a width of 4 modules only, the series DS203NC (“C” stands for “Compact”) allows to reduce the used space to a third compared to a traditional 3P+N solution.
DS203NC range combines in a single device of only four modules width the protection against overcurrents (overload and short circuit) and earth fault currents. The range, developed in accordance to product standards IEC/EN 61009-1 and IEC/EN 61009-2-1, is available in two rated breaking capacities: DS203NC L (4500 A) and DS203NC (6000 A). The extreme breaking capacity Icu according to IEC/EN 60947- 2 is 6 kA for DS203NC L and10 kA for DS203NC, making these devices performing and suitable especially in industrial applications. The range includes AC, A, APR or S versions, with sensitivity levels of 30, 100 or 300 mA and intervention curves B, C or K. The APR versions ensure high immunity to unwanted trippingsdue to transient overvoltage generated, or by capacitive filters of electronic devices like computers, printers, faxes etc.
For these versions, the surge current withstand rises to 3000 A (8/20 wave), compared to 250 A of the standard models. The compatibility with ABB CMS (Circuit Monitoring Systems) enables a consistent management of the network and a permanent monitoring of the circuit, anticipating the occurrence of faults. DS203NC has been tested in accordance to IEC 61373 standard “Railway applications – Rolling stock equipment – Shock and vibration tests” meeting the requirement of Category 1-Class B thus making DS230NC suitable for all the installations subjected to high shocks and vibrations
In addition to its compact size, further elements that distinguish the products of the range of DS203NC residual current circuit breakers with overcurrent protection are the ease of use and management. These features, combined with the quality parameters typical of the ABB brand, make these solutions ideal for applications of international scope, where they can rely on the numerous certificates of conformity issued by leading worldwide regulatory bodies.
The RCBO DS203NC can be used in three phase systems with or without neutral, with no need to add any external resistance: this gives the opportunity to enjoy a unique product code to cover different applications, simplifying logistics and management of parts in stock.
The logistical aspect is further optimized thanks to the radio frequency identification (RFid) tag that equips each unit and allows ABB both to trace the product information, as to track and verify the authenticity of the individual devices through the unique code assigned by ABB in accordance with the standards ISO/ IEC FCD 15693-3. In terms of simplification, these products also consider the needs of the installer.
The devices use the same profile as the family System pro M compact®, with which they can share the accessories via the interface module. Suitable for mounting on DIN rail thanks to the simple fixing device, the RCBOs DS203NC have terminals with two slots that allow to use different types of conductors: one housing is designed for cables up to 25 mm2, the other for busbars or cables up to 10 mm2. The devices can be supplied both from bottom and top terminals. In addition to ensuring maximum flexibility, this set of features allows to meet the different installation habits in different countries. This is further supported by the reliability and warranty of the ABB brand and a quality and compliance to standards that are tested and approved by many global bodies, including IMQ, VDE and KEMA. The framework of the features is complemented by numerous measures designed to optimize the operation, to facilitate troubleshooting and to reduce inefficiencies and downtime. Notable among them are the tripping indicator, the contact position indicator to ease the identification of causes of fault.
