By installing an TOSUNlux RCCB, you can ensure that your home or workplace is protected from electrical hazards and that you and your loved ones are safe from harm

TOSUNlux Residual Current Circuit Breaker

An RCCB is a leakage current sensing device that automatically measures and detects earth leakage in a circuit, providing protection against electric shocks, electrocution, and fires by disconnecting the circuit when the rated sensitivity is exceeded.

TSL3-63 RCCBs incorporate the same housing and installation features as the MCBs. With a range that includes pulse current sensitive and super immune devices, there’s a unit for every application. It complies with IEC61008-1 standard and is certified by INTERTEK. It can be used in circuits with AC 50-60Hz, rated voltage up to 415V, and rated current up to 63A.

The TSL3-63B is an updated version of the RCCB that provides complete residual current detection and can protect both AC and DC circuits.

Here are some frequently asked questions about Residual Current Circuit Breaker:

RCCB works on the principle of Kirchhoff’s law, which states that the incoming current must be equal to the outgoing current in a circuit. RCCB compares the difference in current values between live and neutral wires. Ideally, the current flowing to the circuit from the live wire should be the same as that flowing through the neutral wire. In case of a fault, the current from the neutral wire is reduced, and the differential between the two is known as Residual Current. When there is an imbalance between the phase and neutral, the RCCB trips to protect against electrical hazards.
The working of RCCB electrical devices is based on the principle of Kirchhoff’s current law, which means that the sum of currents entering a node must equal the sum of currents leaving the node. The RCCB is connected between the live wire and the load, and it continuously senses and compares any differences in the current between the neutral and live wires. If the current flowing through the live wire is not equal to the current flowing through the neutral wire, the RCCB trips and disconnects the circuit in a fraction of a second.

There are two main types of RCCBs (Residual Current Circuit Breakers) based on their operating characteristics:

AC RCCB (Type AC RCCB): AC RCCBs are designed to protect against residual current with an alternating current (AC) waveform. They are suitable for most residential and general-purpose applications where the electrical load consists primarily of AC-powered devices. AC RCCBs can effectively detect and trip in the presence of sinusoidal AC leakage currents.

A (or A-Type) RCCB (Type A RCCB): A-Type RCCBs are more versatile and can provide protection against a wider range of residual currents, including both AC and pulsating DC (direct current) leakage currents. These RCCBs are suitable for installations where electronic equipment with rectifiers or electronic switches is used. Type A RCCBs are more sensitive to various types of leakage currents and are designed to offer enhanced safety in modern electrical systems.

Here are some general guidelines for selecting the recommended level of an RCCB:

  1. Residential Applications:

    • 30 mA RCCB: In residential settings, especially in areas where people are more likely to come into contact with electrical equipment and appliances, a 30 mA RCCB is commonly recommended. This level of sensitivity provides better protection against electric shock and is suitable for most residential circuits.
  2. Commercial and Industrial Applications:

    • 100 mA RCCB: In some commercial and industrial settings where there may be equipment with higher leakage currents, a 100 mA RCCB might be used. These installations typically have more specialized requirements, and the choice of sensitivity should align with the specific needs and risks associated with the equipment and processes.
  3. Specialized Applications:

    • For certain specialized applications, such as medical facilities or industrial environments with specific safety requirements, even lower sensitivity RCCBs may be used, such as 10 mA or 6 mA RCCBs. These provide a higher level of protection but can also be more sensitive to minor leakage currents, which may lead to nuisance tripping.

A TSL1-63 Residual Current Circuit Breaker is a specific type of electrical protection device used in electrical circuits to protect against electric shock and fire hazards caused by ground faults or leakage currents. These circuit breakers are designed to interrupt the circuit when they detect a residual current that exceeds a predetermined threshold.

It is usually installed in circuits connected to outlets, lighting, and other electrical loads to protect individuals and property from electrical failures.

It is usually installed in switchboards and subpanels to protect people and equipment and ground faults

It can be used in outdoor electrical installations, such as in garden lighting, swimming pool circuits, or outdoor power outlets. They help prevent electric shock hazards in wet or damp environments.

these circuit breakers may be used in boats, RVs, and other recreational vehicles to protect against electric shocks and fire hazards in marine or mobile environments.

The Complete Guide to residual current circuit breaker (RCCB or RCD)

Definition: A Residual Current Circuit Breaker (RCCB) is an electrical device that is designed to detect and trip against electrical leakage currents, providing protection against electric shock. RCCBs are also known as residual current devices (RCDs) or earth leakage circuit breakers (ELCBs).

Functions: RCCBs are designed to perform the function of protection against electrical leakage currents, which can cause electric shock. They detect the difference between the current flowing in the live and neutral wires and trip the circuit if the difference exceeds a certain threshold.

Types: There are different types of RCCBs, including Type AC RCCB, which is designed to detect and trip against alternating current (AC) leakage currents, and Type A RCCB, which is designed to detect and trip against both AC and pulsating direct current (DC) leakage currents.

Choosing the right RCCB: When choosing the right RCCB, it is important to consider the type of circuit, the load, and the environment. It is recommended to consult with a qualified electrician to ensure that the RCCB is installed correctly and meets the necessary safety standards.

Installation: RCCBs can be installed in a variety of locations, including distribution boards, consumer units, and plug sockets. They can be installed as a single unit or as a unit that is assembled from a residual current unit and a circuit breaker before it is installed in a low-voltage switchgear.
