Qu'est-ce qu'un panneau de disjoncteurs ?
Le panneau de disjoncteurs is a metal box that houses the main circuit breaker and rows of branch circuit breakers inside. It is usually located on the wall of your home.
On the one hand, The KDM breaker panel can safely distribute the main electrical energy connected from the power grid to each independent circuit in your home, which provides power for appliances such as lights and sockets. On the other hand, as the core component of the entire circuit system, it monitors and protects each circuit in real time through internal circuit breakers to prevent electrical faults from causing danger.
- Working Principle: Each circuit breaker within the panel is connected to a specific circuit and is equipped with a precise sensing device inside. When an overload or short circuit occurs in this circuit, the induction device inside the circuit breaker will be triggered immediately, driving the switch to trip rapidly to automatically cut off the power supply of this circuit. After the fault is eliminated, you can manually close the switch to reset it and restore the power supply.
Components of the Breaker Panel
Main Circuit Breaker
The main circuit breaker is a large switch that controls the on-off of all power entering the distribution board. Its rated current determines your total power consumption capacity. In case of an emergency, you can safely cut off the power supply to all the circuits in the room at one time by pulling the main circuit breaker.
Disjoncteur
Branch circuit breakers are a row of small switches arranged in a distribution board, each responsible for controlling and protecting an independent circuit. It is equipped with a precise sensing device that can continuously monitor the circuit current. Once the circuit it is responsible for is overloaded or short-circuited, this circuit breaker will immediately trip automatically to cut off the power supply, thereby preventing the wires from overheating and causing a fire. After the fault is eliminated, you can manually reset it.
Tableau de distribution
The distribution panel usually refers to the internal installation frame and conductive skeleton of the entire circuit breaker panel. It consists of a sturdy insulating board and the busbars fixed on it. The power of the main circuit breaker is delivered to the access point of each branch circuit breaker through busbars, thus achieving safe power distribution.
Protective Cover
The protective cover is the outermost metal or plastic door cover of the circuit breaker panel. It tightly encloses all the live parts inside the distribution board, which prevents you from accidentally touching dangerous parts such as busbars and circuit breaker terminals, and avoiding electric shock. The cover is usually affixed with a circuit index label, indicating the purpose corresponding to each circuit breaker.
The Functions of the Breaker Panel
Distribution of Electricity
Our circuit breaker panel receives a single main power supply from the power grid and safely and orderly distributes it to multiple independent branch circuits. Each circuit is dedicated to a specific area or purpose, which achieves modular and refined management of power.
Overload and Short-Circuit Protection
Each circuit breaker in our panel is equipped with a real-time monitoring function. When a circuit is overloaded due to the connection of too many devices or a short circuit is caused by a line fault, the circuit breaker will trip automatically in an instant to cut off the power supply of that circuit. This can effectively prevent problems such as overheating of wires or melting of insulation layers, fundamentally avoiding the occurrence of fires.
Independent Circuit Control
Each circuit breaker independently controls a circuit. When a certain line needs maintenance or malfunctions, you can directly turn off the corresponding circuit breaker for operation without cutting off the main power supply. This greatly enhances the flexibility of your electricity usage and the safety of maintenance, while ensuring normal power supply to other areas.
Emergency Power Outage
The main circuit breaker on the panel can cut off the entire power supply with one click in case of an emergency. In addition, the inner side of the panel door is usually equipped with a circuit identification diagram clearly indicating the circuit corresponding to each circuit breaker, which is convenient for you to quickly identify and manage the power consumption system.
Grounding Safety Guarantee
Our circuit breaker panel is equipped with a dedicated grounding bar inside, which can gather the ground wires of all circuits and reliably connect them to the ground. When leakage or insulation faults occur, it can provide a low-impedance path for abnormal currents, which prompts the circuit breaker to trip quickly while protecting you from the risk of electric shock.
The Characteristics of KDM Breaker Panel
Modular Structure
The interior of our circuit breaker panel is composed of main circuit breakers, branch circuit breakers, grounding bars and other components. You can flexibly add or adjust the circuit according to your electricity demand, and ensure the reliable connection of each component through standardized interfaces, which is convenient for your daily installation and maintenance.
Sécurité
The metal protective housing of the circuit breaker panel can prevent you from accidentally touching the live parts. When a fault current occurs, the circuit breaker will automatically trip to quickly cut off the fault current, while the insulated busbar can avoid internal short circuits. In addition, some of the new panels are also equipped with leakage protection functions, further enhancing the safety guarantee for you.
Convenience
Each branch circuit breaker is equipped with a clear switch status indicator. You can observe the circuit’s on-off status without opening the panel, and you can manually reset the circuit breaker switch. The inner side of the panel door usually has a clear circuit identification diagram attached, which is convenient for your daily management and troubleshooting.
Strong Compatibility
The number of slots on our circuit breaker panels can be selected according to your power consumption scale and supports subsequent expansion. Its electrical specifications and mechanical interfaces all comply with industry standards, and it can be compatible with circuit breakers of different brands but with matching specifications, which provides you with flexible configuration options.
Strong Adaptability
The circuit breaker panel can be installed indoors or outdoors according to your usage scenario. The outdoor type usually has waterproof, dustproof and corrosion-resistant characteristics. The installation method, material and protection level of the panel can also be adapted to your specific environmental requirements to ensure its long-term stable operation.
Precautions for Using Breaker Panels
Operated by Professionals
Even if the main circuit breaker is turned off, some areas inside the panel remain electrified, posing a fatal risk of electric shock. Therefore, all internal wiring, replacement or addition of circuit breakers and other operations must be carried out by professionals. You are only allowed to operate external switches.
Identify Tripping Warnings
You should first turn off all the electrical appliances on this circuit, then fully push the circuit breaker to the OFF position, and finally reset it to ON. If the circuit breaker trips again after resetting, it indicates that there is an overload, short circuit or equipment failure in the circuit. Professional inspection must be carried out and the circuit breaker should not be forcibly kept closed.
Keep the Panel Markings Clear and the Channels Unobstructed
You must ensure that the circuit index labels on the inner side of the panel door are accurate and clear, indicating the purpose corresponding to each circuit breaker. There must be unobstructed space near the panel so that you can approach and operate safely and quickly in an emergency.
Prohibited from Improper Use
It is strictly prohibited to clamp a circuit breaker with metal objects or non-standard components to make it undergo strong conduction. In addition, unless explicitly supported by the panel, you must not use two circuit breakers to share one standard slot for temporarily adding circuits. This will completely undermine the protective function of the panel and is highly likely to cause an electrical fire.
Regular Inspection
You need to regularly observe the condition of the circuit breaker panel. If you find that the circuit breaker or the connection points of the wires are overheating, making abnormal noises, having a burnt smell, or the circuit breaker switch is loose, you should immediately stop using it and contact professionals for inspection and repair.
