LCTC Product
According to their functions, smart circuit breaker can be divided into two categories.
NO metering, it has functions such as remote adjustable, power-off memory.
With metering and VA protect. In addition to the functions of LWF-63T, it also has other functions, such as energy monitoring, Current limit.
View Voltage and CurrentReadings at Any Time
Protects your system from voltage fluctuations
Remote Control and Real-Time Monitoring of Equipment
The LCTC smart circuit breaker supports WiFi connection and cloud remote control. Your mobile phone can act as a remote control, eliminating the limitations of time and space, and monitor your signal devices anytime and anywhere, any deviation can be detected immediately and appropriate measures can be taken. So it is highly suitable for use in homes, commercial Spaces and other environments where installation is not required and no one is present.


Much Easier by Using Smart Home Integration
Connect the LCTC smart circuit breaker to various devices and platforms, such as Tuya Smart and Google Assistant. This enables intelligent and shared power usage control, allowing for automatic switching based on scenarios and conditions. It also enables intelligent and system management of smart circuit breakers, reduces manual operation, optimizes energy consumption and extends lifespan.
Choosing the right smart circuit breaker depends on your application voltage, current requirement, control method, and protection needs.
For LCTC smart circuit breakers, we recommend confirming the following parameters before selection:
Rated voltage: AC110V or AC220V power systems
Current range: adjustable from 1A to 63A
Maximum power capacity: up to 15KW
Control method: Tuya Smart APP control and voice control
Protection requirements: overvoltage, undervoltage, overcurrent, overload, and delay protection
For residential, commercial buildings, smart energy management, and remote electrical control applications, our WiFi smart circuit breaker provides a convenient solution. If you need a customized model for a specific current rating, enclosure design, or batch application, LCTC can recommend the suitable configuration based on your system requirements.
A traditional circuit breaker mainly provides basic electrical protection, such as overload and overcurrent protection, while a smart circuit breaker adds intelligent monitoring and remote control functions.
Compared with conventional breakers, LCTC smart circuit breakers provide additional features such as mobile APP remote ON/OFF control, voice control through smart home platforms, timer scheduling, real-time, electricity consumption monitoring, adjustable protection parameters.
For upgrading existing electrical systems, a smart circuit breaker is a practical choice when remote management and energy monitoring are required. Our engineers usually recommend selecting smart breakers based on whether remote operation or energy management functions are needed in the application.
LCTC smart circuit breakers use Tuya Smart wireless communication technology, allowing users to connect and control the breaker through a mobile APP.
The built-in wireless connection supports remote ON/OFF control, timer scheduling, energy monitoring, smart home integration.
LCTC smart circuit breakers are available for common AC power systems with different voltage and current options.
LCTC smart circuit breakers specifications include:
Rated voltage: AC110V / AC220V
Adjustable current setting: 1A-63A
Maximum power capacity: up to 15KW
Frequency: 50/60Hz
When selecting a model, we recommend choosing the rated current according to the actual load rather than selecting based only on equipment power. Our engineers can help calculate the suitable current rating according to your application and operating conditions.
LCTC smart circuit breakers can be used in the AC side protection and monitoring systems of solar PV applications, where remote control and energy monitoring are required.
They are suitable for applications such as residential solar power systems, small commercial PV installations, smart energy management systems.
For solar applications, customers should confirm system voltage, current rating, and installation requirements before selection. For DC photovoltaic protection, a dedicated DC circuit breaker is normally recommended.
LCTC smart circuit breakers can be used for auxiliary protection and smart energy management applications in EV charging environments.
They provide functions including remote circuit control, current monitoring, overload protection, scheduled operation.
However, EV charging systems require careful matching of rated current, voltage, and protection requirements. For high-power EV charging applications, we recommend selecting the breaker based on the charger specifications and system design.
LCTC smart circuit breakers provide overload and overcurrent protection by continuously monitoring electrical conditions and disconnecting the circuit when abnormal current levels are detected.
The integrated protection functions help prevent excessive current caused by overloaded equipment, electrical damage caused by abnormal voltage conditions, unnecessary equipment downtime.
For applications with strict short-circuit protection requirements, we recommend confirming the short-circuit rating and system protection design before choosing the breaker model.
Sure. Even without a network connection, it still has basic security features. It is only applicable to network connections that use remote control or applications.
Of course we have. The voltage range of the LCTC smart circuit breaker can reach 300V, so 240V is very useful.
