The intelligent leakage circuit breaker with overload protection (intelligent RCBO / intelligent residual current circuit breaker) is a new generation of electrical safety device that integrates residual current protection, overload protection, short-circuit protection, and IoT smart technology. It is an upgraded version of the intelligent residual current circuit breaker (RCBO). Building on the traditional leakage circuit breaker’s "personal electric shock protection + circuit overload/short-circuit protection," it incorporates WiFi, Bluetooth, 4G, and other communication technologies to achieve remote monitoring, intelligent alerts, and linkage control, specifically designed for electrical safety in homes, commercial buildings, and industrial sites.

The dual-display over-voltage and under-voltage protector is an electrical safety device that integrates dual-screen visual display with precise voltage protection, designed specifically for small to medium electrical applications such as homes and shops. It simultaneously presents two types of key electrical parameters (such as real-time voltage + device status, or incoming voltage + load voltage) through dual display modules (LED digital tube / LCD screen). In addition to the traditional over-voltage and under-voltage protection functions, it also adds visual monitoring features.

The three-display overvoltage and undervoltage protector is an upgraded electrical safety device that integrates triple parameter display with comprehensive voltage protection, suitable for scenarios with higher power monitoring requirements (such as small computer rooms, precision equipment rooms, and commercial shops). Through three screens or a three-in-one display module, it simultaneously shows three key parameters: voltage, current, and power/frequency/status. In addition to overvoltage and undervoltage protection, it also adds load current and power monitoring functions.

The HHB3 series features the latest exterior design and upgraded accessories, making it an internationally popular small circuit breaker. This product prevents insulation aging, heating, and even fire hazards caused by long-term overload of wires. When faults such as direct contact between live and neutral wires occur in the circuit, resulting in a huge short-circuit current (usually several times or even dozens of times the rated current), the electromagnetic release inside the circuit breaker will instantly generate strong magnetic force, quickly pushing the release mechanism to act and cutting off the power supply in a very short time (usually milliseconds). Prevent huge short-circuit currents from burning electrical appliances and wires, and even causing more serious electrical fires and personal electric shock accidents.

The DZ47LE-63 D20 leakage miniature circuit breaker is a compact protective device designed for reliable control and safety in low-voltage distribution systems. It integrates overload protection, short-circuit protection, and residual current (leakage) protection into one unit, offering stable performance for residential and commercial power circuits.

Key Features

Triple Protection Function: Automatically disconnects the circuit when detecting overload, short circuit, or leakage current, reducing electrical hazards.

Rated Specifications: With a rated current of 20A and a leakage protection current of 30mA, it is suitable for lighting, socket, and small-power equipment circuits.

Quick Response Mechanism: The device reacts rapidly to abnormal current, minimizing potential risk to people and equipment.

Durable Housing: Made with flame-retardant materials to enhance overall safety and lifespan.

User-Friendly Design: Clear indicator window and manual reset lever allow easy status identification and operation.

Flexible Installation: Compatible with standard DIN rails, enabling tool-free and efficient installation in most distribution boxes.

Applications
Ideal for households, small commercial spaces, workshops, and environments where additional leakage protection is required, particularly in areas with moisture or frequent human contact.

The DZ47LE series residual current circuit breaker has the characteristics of complete structure, reliable performance, high breaking capacity, and beautiful and compact appearance. The shell and main components are made of impact resistant and highly flame-retardant materials. Suitable for places with AC 50Hz or 60Hz, rated working voltage of 400V and below, and rated current of 6A to 63A.

Purpose and Features
The DZ47LE-63 standard small residual current circuit breaker is a widely applicable grounding fault protection device, which can provide protection products with different action values such as 30mA and 50mA according to different protection needs. Due to the use of fog sequence current transformers and integrated amplification circuits, the sensitivity of the protective circuit breaker is quite high. It can detect ground fault currents, which can significantly reduce the risk of fire and electric shock. The DZ47LE-63 standard small residual current protection circuit breaker can achieve:
Provide personal protection for indirect contact
Provide supplementary personal protection for direct contact
Provide protection against insulation faults in electrical equipment

Product Description
This 4P surge lightning protection device supports an ultra-large current capacity of 40kA/60kA, capable of instantly discharging strong surges generated by lightning strikes and grid fluctuations.
High-quality zinc oxide varistors (MOV) are adopted, featuring low leakage current and anti-aging properties. Combined with temperature control circuit breaker and overcurrent protection, the module will automatically trip when it overheats or fails, completely eliminating the risk of fire.
It is equipped with built-in status indicator lights. Some models support remote alarm terminals and can be connected to the monitoring system to provide real-time feedback on the working status.

Differentiated selling points
It simultaneously protects against three-phase live wires (L1/L2/L3) and neutral wires (N), covering 380V three-phase systems, and is particularly suitable for three-phase loads such as industrial equipment and photovoltaic inverters.
The modular design allows faulty modules to be directly plugged and unplugged for replacement without cutting off the main power supply, reducing the risk of downtime.

Product Description
This is a dual power automatic transfer switch (ATS) used to automatically/manually switch between common power supply and backup power supply, ensuring continuous power supply to the load. Suitable for important scenarios such as firefighting, elevators, and medical facilities where power outages are not allowed.

Core functions
1.Auto Switch
When in the "Auto" mode, monitor the voltage/frequency of the commonly used power supply in real time. When the commonly used power supply fails (voltage loss, undervoltage, phase loss), automatically switch to the backup power supply; After the common power supply is restored, it will automatically switch back.
2.Manual switch
When in the "Manual" position, manually select "Common Power (A)", "Backup Power (B)" or "Off" through the red knob.
3.status indicator
Red light on: The current power supply is the common power supply (A);
Green light on: The current power supply is a backup power supply (B);
Icon identification: "Tower" represents common power supply (mains), and "Generator" represents backup power supply.

Precautions
Prohibit frequent switching (automatic interval ≥ 30 seconds, manual interval ≥ 10 seconds);
Regularly (quarterly) test the automatic switching function and check if the wiring terminals are loose;
Only applicable to the marked voltage/current range, to avoid overload.
