All Your Questions
Here are some frequently asked questions about TOSUNlux Residual Current Operated Circuit Breaker：
An RCBO (Residual Current Operated Circuit Breaker) is a device that ensures electrical safety by monitoring current in a circuit. It consists of an RCD (Residual Current Device) that detects ground faults and a circuit breaker that protects against overcurrent situations. When an imbalance or fault is detected, the RCD trips, cutting off the electricity flow to prevent electric shocks and fire hazards. Additionally, the circuit breaker trips if the current exceeds a safe level. This combination of functions makes the RCBO an essential component in electrical systems, providing reliable protection against electrical faults and enhancing overall safety.
An RCD is a standalone device that is designed to protect against electrical shocks caused by ground faults. It continuously monitors the current flowing in a circuit and quickly detects any imbalance between the live and neutral wires. If a fault is detected, such as current leakage to the ground, the RCD trips and cuts off the electricity supply, preventing potential electric shocks.
On the other hand, an RCBO combines the functions of an RCD and a circuit breaker into a single device. In addition to providing protection against ground faults, an RCBO also safeguards against overcurrent situations. It can detect both leakage current and excessive current flow, offering a dual layer of protection. If a fault or overcurrent event occurs, the RCBO trips, disconnecting the circuit to ensure safety.
Ensure safety by turning off the power supply to the circuit.
Identify the line (hot/live) and neutral wires in the electrical panel.
Connect the line wire from the power source to the RCBO’s line terminal. Connect the neutral wire to the RCBO’s neutral terminal.
Identify the load wires going to the devices or circuits you want to protect.
Connect the load line wire to the RCBO’s load terminal. Connect the load neutral wire to the RCBO’s load neutral terminal.
Double-check all connections for accuracy and security. Avoid exposed or touching wires.
Restore the power supply and test the RCBO to ensure proper functioning.
Remember to consult a qualified electrician or follow the manufacturer’s instructions for the specific RCBO model. Electrical work should be performed by professionals or individuals with appropriate knowledge to ensure safety and compliance with regulations.

Application
The TSN1-40L Residual Current Operated Circuit Breaker is suitable for use in a variety of applications where residual current protection is required, such as in residential, commercial, and industrial settings. It can be used to protect electrical equipment and installations against earth leakage and can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of the trunk. The device can be combined with over-current protection (fuses or circuit breakers) to provide comprehensive protection against electrical hazards

In most cases, the MCB or RCBO you choose should be rated for the current they handle. You should also check their trip characteristics and look for extra features and safety approvals. Your electrical installation is unique, so the right MCB or RCBO is crucial. Consider these factors when selecting MCB or RCBO.
The overcurrent characteristics of Type B, C or D MCB or RCBO are determined by the trip times of the devices. In real-world situations, it is important to ensure that the breakers trip within a reasonable time. For example, an MCB can trip in forty seconds at two times its rated current. It will allow for this brief surge to occur and prevent damage to the device.
An RCBO is a resizable circuit breaker. It can be used to protect a lighting circuit and provides protection from electric shocks. Its main purpose is to interrupt the flow of power to a water heater. An MCB or RCBO is a device that monitors the flow of current in a line and interrupts the circuit during a short circuit, overload, or earth leakage. These devices are also used in distribution boards to protect from overcurrent.
An RCBO or MCB can protect against electric shock or fire by detecting overcurrent. MCBs are a safer alternative to RCCBs and can be used in homes. They provide circuit isolation but are less durable than RCBs. RCBOs are generally designed to interrupt power for a short period of time and are often safer to use.
A manual circuit breaker (MCB) is an electrical device that trips in an overload or short circuit situation. It causes an interruption of the load circuit when it trips. The operating knob moved to the off position when the MCB tripped. There are several types of MCBs, with short circuit breaking capacities. You need to consider the basic applications of Type B, C or D devices. Type B devices are well-suited for domestic use, providing reliable protection in residential settings. Type C devices, on the other hand, are ideal for commercial and industrial applications, delivering robust performance in demanding environments. Finally, Type D devices are specifically designed for industries with high inrush currents, ensuring effective protection in such scenarios. By considering these distinctions, you can make an informed decision and choose the appropriate device based on your specific application requirements.
Different MCBs and RCBOs offer various trip characteristics, such as B, C, or D curves. Consider the type of load and its starting current to select the appropriate trip curve for optimal protection and sensitivity. Tripping characteristics of MCBs are illustrated graphically in a trip curve chart. The thermal region represents the bi-metal tripping unit, and it gradually slopes downwards as a result of a gradual overload. The B-type MCB has a tripping range of 3 to 5 times the rated current. A D curve tripping characteristic is four seconds slower than a K curve. This gives the circuit more time to ride through high in-rush at start-up. The C-type tripping time is approximately 5 to 10 times. The D curve has a tripping range of 10 to 20 times the rated current.
The most important thing to know when selecting an MCB or RCBO is how to troubleshoot it. You can also check the safety rating of the device before you purchase it to avoid unwanted tripping.
Both types of MCBs and RCBOs can trip a circuit when an overcurrent occurs. However, an RCBO may not trip an overcurrent if it detects a low voltage or an overcurrent condition. An MCB that protects against both types of overloads and short circuits i
