JCRB2-100 Type B RCDs

The JCRB2-100 Type B RCD is designed to provide comprehensive protection against residual fault current and ground leakage for a variety of AC power applications with specific waveform characteristics. These RCDs are particularly suitable for use in environments where smooth and/or pulsating DC residual currents may be present, non-sinusoidal waveforms are expected, or frequencies in excess of 50Hz are expected. Examples of applications that would benefit from the use of Type B RCDs include electric vehicle charging stations, certain single-phase equipment, micro-generation or SSEG (small-scale generators) such as solar panels and wind turbines. The versatility and effectiveness of Type B RCDs make them an essential component in ensuring the electrical safety and reliability of modern power systems.

    Introduction

    Type B RCDs (Residual Current Devices) play a vital role in ensuring electrical safety in a variety of applications. Its unique design enables it to protect against both AC and DC faults, making it particularly suitable for environments with DC-sensitive loads such as electric vehicles, renewable energy systems and industrial machinery. As the demand for these technologies continues to grow, the importance of Type B RCDs in modern electrical installations cannot be overstated.
    Type B RCDs are able to detect AC and DC residual currents, thus providing a higher level of safety compared to conventional RCDs. While Type A RCDs are designed to trip in the event of an AC fault, Type B RCDs are also capable of detecting DC residual current, making them critical for meeting the changing electrical safety needs of today's applications. This is particularly important as the adoption of renewable energy systems and electric vehicles poses new challenges and requirements for electrical protection.
    The ability of Type B RCDs to provide protection in the presence of DC sensitive loads is a significant advantage. For example, electric vehicles rely on direct current to drive, and appropriate protection measures need to be implemented to ensure the safety of the vehicle and its charging infrastructure. Likewise, renewable energy systems such as solar panels operate on DC power, making Type B RCDs an indispensable component in these installations.  The versatility and advanced safety features of Type B RCDs make them an essential element in protecting modern electrical systems and equipment.

    The most important features

    The DIN rail mounted 2-pole/single-phase Type B RCD provides the necessary protection for electrical systems. This RCD has a trip sensitivity of 30mA, a current rating of 63A and a voltage rating of 230V AC and is designed to protect against residual fault currents and leakage in a variety of applications. Its short-circuit current capacity of 10kA ensures reliable performance even in the event of a fault.
    It's worth noting that the RCD's IP20 rating means it requires an enclosure suitable for outdoor use to ensure it's fully protected from environmental factors. In addition, it complies with standards such as IEC/EN 62423 and IEC/EN 61008-1, emphasizing its reliability and compliance with industry regulations, giving users and installers peace of mind.

    What is a Type B RCD?
    Type B RCD is not the same as Type B MCB or RCBO, although the terminology is similar and may cause confusion. It is worth noting that the Type B designation refers to the thermal properties in MCB/RCBO and the magnetic properties in RCCB/RCD. This distinction is crucial to avoid misunderstandings, especially when encountering products such as RCBOs with dual characteristics, comparing the magnetic element of the RCBO to the thermal element (which may be an AC or A type magnetic element and a B or C type Thermal RCBO) combined.

    How do Type B RCDs work?
    Type B RCDs usually contain two residual current detection systems to ensure comprehensive protection. The first system used “fluxgate” technology to enable the RCD to detect smooth DC current. The second system uses technology similar to Type AC and Type A RCDs to provide voltage-independent detection. This dual approach enables Type B RCDs to effectively identify and respond to a wide range of fault currents, both AC and DC, making them suitable for a variety of applications where such currents may be present.
