It is for this reason that electrical safety has for the most part become a primary rider in the ever-evolving world of technology. Electrical circuits can be very useful for various purposes in society but then again they come with various dangers that may be realized if they are not well dealt with. This is the role that is played by the Residual Current Devices (RCDs) and Residual Current Circuit Breakers (RCCBs). These are intended to protect individuals and assets from electrical risks by cutting off the circuit rapidly when an unfavorable portion or leakage current is present. One example of such a device is the JCR2-125 RCD, which has been purposely designed and developed to minimize the likelihood of receiving a fatal electric shock and minimize the risks associated with electrical fires.
Understanding the JCR2-125 RCD
The JCR2-125 RCD is an electrical device that is highly technical since its main function is to monitor leakage currents to protect the users. If there is a leakage current it means that some portion of the test current is causing current through a non-expected path such as through the body or insulation breakdown. The JCR2-125 is specifically developed to trip off the circuit in such incidences as a way of safeguarding from adverse injuries or losses.
The main features of the new JCR2-125 RCD circuit breaker are described as follows:
The JCR2-125 RCD comes with several critical features that make it highly effective and reliable in ensuring electrical safety: The JCR2-125 RCD comes with several critical features that make it highly effective and reliable in ensuring electrical safety:
Electromagnetic Type: It also ensures that there is a quick and proper breaking off of the circuit once leakage currents are detected.
Earth Leakage Protection: Reduces risk from electrical faults which can cause electric shocks or fires.
High Breaking Capacity: It has a breaking capacity of up to 6kA, which makes it capable of interrupting not only through a normal current but also a large fault current at the same time without getting damaged.

In this research, there are different RCDs, and below are the types of RCDs and their applications.
The different types of residual current are used to classify RCDs depending on their sensitivity. The JCR2-125 offers both Type AC and Type A RCDs, each suited for specific applications: The JCR2-125 offers both Type AC and Type A RCDs, each suited for specific applications:
Type AC RCDs
Finally, let the type AC RCDs detect the sinusoidal residual alternating current. These are commonly found in home use to guard equipment that is resistive, capacitive, or inductive without using any electronics. They guard against over-swing as well as offer immediate counter-steer as soon as an imbalance is observed.
Type A RCDs
Whereas Type A RCDs can recognize sinusoidal residual current as well as residual pulsating direct current as small as 6mA of current at AC frequency. This makes them appropriate for use where electrical appliances are involved especially in complicated electrical circuitry since they offer better protection in such systems as compared to other types of resistors.
Importance of Tripping Sensitivity
RCD tripping sensitivity refers to the ability of the RCD to respond to the fault that triggered the initiation process, within a certain time. The JCR2-125 offers three levels of sensitivity: The JCR2-125 offers three levels of sensitivity:
30mA: Admits further measures of safeguard against direct touch with live parts, which again makes the equipment good for individual safety.
100mA: Harmonized with the earth system to avoid the threats of indirect touching system and decreased the hazard related to electric fires.
300mA: Provides shielding against second touch and is most advantageous in protection against fires caused by electrical issues.
