Siemens RCCB Series: Various Models

Different series of Siemens RCCB (Residual Current Circuit Breaker) play a crucial role in protecting equipment, individuals, and industrial processes, serving as one of the strengths and most important electrical components in the industry. With technological advancements and increasing industrial needs, RCCBs are produced with more features and capabilities to meet the expanding and complex requirements of various industries.

In the following, we will examine and introduce various series of Siemens RCCBs, discussing their features, applications, and their significance in protecting electrical equipment and different industrial processes. Additionally, an effort has been made to familiarize the reader with the theoretical foundations and key concepts of these devices.

Siemens RCCB Series 5SV1 Compact RCBOs

The Siemens RCCB Series 5SV1 Compact (RCBOs) is a combination of RCCB and MCB in a compact design for protection against electric shock, fire, and line protection. To safeguard individuals and protect against fire, the residual current type AC section acts in the presence of sinusoidal AC residual currents, and type A also operates in the presence of pulsed DC residual currents. RCCBs with a nominal residual current of up to 30 milliamps are used for protecting individuals, materials, and fire protection, as well as additional protection against direct contact. The MCB section of the RCCB protects lines against overloads and short circuits and is available in B and C characteristics. Allocating to each branch circuit prevents unwanted tripping of unaffected circuits created by the accumulation of leakage currents associated with the performance or by transient current pulses during switching operations. RCCBs include a section for identifying fault currents and an additional identification section. They are equipped with a bi-metallic thermal release/time-delay and a time-dependent (thermal non-metallic) for additional low-current protection and with an electromagnetic instantaneous release for overloads and short-term faults. The special contact materials used ensure long service life and provide a high level of protection against welding contacts.

Siemens Electromechanical RCBO – The World’s Most Compact 1 Megawatt RCBO:

• With a slim design width of only 18 millimeters, the Siemens Electromechanical RCBO is ideally suited for new constructions and the refurbishment market, such as in old buildings.
• In new constructions, implementing low-volume distribution panels can save 50% of space compared to the 2 Megawatt version, often making them more cost-effective.
• Especially in projects requiring individual residual current protection, smaller distribution panels can be installed, resulting in significant cost savings.
• In old buildings, replacing existing 1-pole MCBs with a 5SV1 RCBO (without the need for additional space in the distribution panel) is straightforward.
• This replacement increases the level of protection in electrified circuits and enhances personal safety.
• With the formation of 5ST low-profile busbars, devices can easily be installed and connected even in narrow distribution panels.
• The new compact 5SV1 RCBOs come with an extensive range of accessories, such as auxiliary switches, fault signal indicators, and arc fault detection devices.
• Connecting the RCBO with a 5SM6 arc fault detection unit results in a combination that provides maximum protection against residual currents, overloads/short circuits, and arc faults in a 2 Megawatt configuration. This combination offers the highest level of protection for individuals and assets.
