Key Features
Three-Phase Energy Monitoring
Designed for three-phase electrical installations, the KWS-306WF can monitor important electrical parameters and energy consumption, helping users understand how their electrical system is performing.
Depending on the supported configuration, monitored parameters may include:
- Voltage
- Current
- Power
- Energy consumption
- Electrical frequency
- Other electrical status information
This makes it useful for monitoring household distribution boards, commercial electrical panels, workshops, equipment, and other three-phase applications.
WiFi & Tuya Smart Connectivity
The built-in WiFi functionality enables smart monitoring through the Tuya-compatible smart-home ecosystem.
Users can potentially check electrical information remotely using a compatible mobile application, making it easier to keep track of energy usage without being physically present at the electrical panel.
Smart functions may include:
- Remote electrical status monitoring
- Remote switching/control where supported
- Energy consumption monitoring
- Device status checking
- Smart-home integration through the Tuya platform
- Notifications or protection-status information where supported by the app/device configuration
Note: Exact app functions can vary according to firmware, Tuya platform configuration, and the specific version supplied.
Electrical Protection Functions
The KWS-306WF is designed not only as an energy monitor but also as a smart electrical protection device. Its protection functions can help respond to abnormal electrical conditions according to the device’s configured protection parameters.
The product listing indicates support for functions such as:
- Overvoltage protection
- Undervoltage protection
- Overcurrent protection
- Leakage protection
- Other configurable electrical protection functions depending on the device version
These functions can help reduce the risk associated with abnormal electrical conditions and provide an additional layer of protection within an electrical distribution system.
Up to 80A Current Capacity
The device is rated for applications up to 80A, making it suitable for a wide range of residential, commercial, and light-industrial electrical monitoring applications.
Always ensure that the device’s actual rating, wiring method, circuit protection, and installation conditions are appropriate for the intended load.
DIN Rail Installation
The KWS-306WF features a DIN rail mounting design, allowing it to be installed neatly inside compatible electrical distribution boards, consumer units, control cabinets, and electrical enclosures.
DIN rail installation provides:
- Space-efficient mounting
- Clean electrical-panel organization
- Easy integration into compatible distribution boards
- Convenient access for inspection and maintenance
Real-Time Electrical Visibility
By providing access to electrical measurements and consumption information, the KWS-306WF can help users identify changes in electrical demand and better understand how electricity is being consumed.
This can be particularly useful for:
- Monitoring high-power appliances
- Tracking equipment consumption
- Identifying unusual electrical loads
- Managing electricity usage
- Checking system status remotely
