2. Anti-shock device, RBCO circuit breaker
RCBO (Residual Current Breaker with Overcurrent Protection) is a device that combines an circuit breaker and a residual current sensor. It is used to protect people and equipment from the risk of electric shock and short circuit. When there is leakage current or overload, RCBO will automatically cut off the power supply.
2.1. Structure and operating principles of RBCO
Structure:
Aptomat (MCB): Is a type of circuit that protects against overload and short circuit.
Residual current sensor (RCD): Used to detect leakage current in the circuit.
Combination: RCBO combines both of the above functions into a single device.
Operating principles
When there is leakage current (due to contact with people or damage), the RCD sensor will detect and activate the circuit breaker to cut off the power supply.
If there is an overload, the circuit breaker will also cut off the power to protect the circuit.
DeploymentRCBO Chint is a leakage current circuit breaker with built-in short circuit and overload protection. Here are some applications of RCBO Chint:
In industrial electricity: RCBO Chint is used in industrial electrical systems, factories, and automation lines.
Residential and small businesses: RCBO is suitable for residential power networks, offices, workplaces, and small businesses.
Safety protection: RCBO helps protect the safety of electrical circuits, property and people. It automatically disconnects the circuit when there are problems such as current leakage, overload voltage, and electrical short circuit.
Short circuit protection: RCBO is effective in preventing short circuit when current is overvoltage
3. Contactor NXC-22 220V 50/60Hz Chint | 3 Phase 22A 1NO+1NC
The NXC-22 contactor is an electrical device used to control large or small capacity motors or generators. It works based on the principle of an integrated spring. The NXC-22 contactor has contacts built into it, and they are used to switch on and off the current that activates the controlled devices. Used in factories, plants and industrial-scale production facilities in general.
3.1. Structure and operating principles
Structure:
Electromagnet: Includes the following details:
The coil creates magnetic attraction.
Iron core
The spring acts to push the lid back to its original position.
Arc extinguishing system: Ensures contacts do not burn out and gradually wear out when switching.
Contact system:
Main contact: Allows large current to pass through. When power is applied to the contactor's magnetic circuit, the main contact closes.
Auxiliary contact: For current less than 5A. There are two states: normally closed and normally open. Auxiliary contacts are often installed in the contactor's control circuit system.
Operating principles
When power is applied to the coil, the magnetic force attracts the movable magnetic core and forms a closed magnetic circuit (this time the magnetic force is greater than the reaction force of the spring).
The interlock between the movable magnetic core and the contact system causes the main contact to close and the auxiliary contact to change state.
When the power supply stops, the contactor returns to sleep state.
3.2. Contacter deploy
Contactor Chint NXC-22 has many applications in electrical control systems.
Here are some examples:
Motor control: Contactor NXC-22 is often used to control AC motors in manufacturing plants, factories, and industrial facilities.
Lighting system: Contactor can be applied to turn on/off lights in buildings, factories, and public areas.
Water and pump systems: Contactor NXC-22 helps control water pumps, pumps, and water treatment systems.
Applications in automation: Contactors are used in industrial automation systems to control various devices.

III. The operating principles of JF-302R mutiple sensor and controlling curcuit
1. Sensor indicator JF-302T
A type of sensor used to measure liquid levels in tanks, silos, and water pumping systems. Below is the operating principle of the automatic water pump control circuit using a liquid sensor float:
2. The operating principles of sensor buoy
The plastic float in the sensor is a limit switch. When the water is full, the plastic float floats and activates the limit switch, closing the contact. When the water runs out, the plastic float hangs and the limit switch changes state, opening the contact.
3. Controller diagram
The control circuit includes parts such as CB (circuit breaker), contactor and thermal relay. When the sensor float closes, the control circuit activates the water pump. When the sensor float opens, the control circuit turns off the pump power.
