TOMZN Product Categories: Complete Electrical Protection
1. Miniature Circuit Breaker (MCB)
TOMZN miniature circuit breakers are designed to protect electrical lines from overcurrent and short-circuit faults. The product provides 1P, 2P, 3P and 4P multiple pole selections, and the rated current covers 6A to 125A, which can flexibly adapt to various terminal power distribution requirements.
High Breaking Capacity: The highest breaking capacity can reach 10kA, to ensure that the circuit is quickly cut off when the fault occurs, to ensure the safety of the back-end equipment.
Tripping Curves: Provide B-type ( residential lighting ), C-type ( commercial mixed load ) and D-type ( industrial motor ) tripping curves to meet the protection requirements of different load types.
Compact Installation Design: Standard DIN rail installation method is adopted to save space and facilitate rapid deployment and maintenance.
International Authoritative Certification: Strict compliance with IEC 60898-1 standard manufacturing, stable and reliable quality.
2. Residual Current Devices
TOMZN residual current circuit breaker is the core protection device to prevent electric shock accidents and leakage faults. It can monitor the residual current in the line in real time, and cut off the power supply immediately in the event of leakage, providing a key guarantee for personal safety and equipment operation.
High Sensitivity can be Selected: Provide 10mA, 30mA, 100mA and other action sensitivity, can provide accurate protection for different scenarios (such as wet environment, medical equipment, etc.).
Comprehensive Leakage Protection: Effectively detect and respond to dangerous leakage current to avoid electric shock damage caused by insulation damage or direct contact with the charged body.
Modern Electrical Standard: As an indispensable safety component in modern electrical devices, TOMZN residual devices can significantly improve the safety level of the entire system.
3. Surge Protective Devices (SPDs)
The transient overvoltage caused by lightning strike or large load switching of power grid is very easy to cause irreversible damage to precision electronic equipment. The TOMZN surge protector can quickly absorb and discharge these overvoltage energy and clamp the voltage within a safe range, thereby protecting the back-end equipment and the entire electrical infrastructure.
Strong Surge Suppression: The use of high-quality varistor elements, fast response, large flow capacity, effectively resist the surge impact.
Comprehensive Equipment Protection: Whether it is household smart appliances or industrial control equipment, SPD can fundamentally reduce the maintenance and replacement costs caused by overvoltage.
Stable and Reliable: Product design strictly follows relevant international standards to ensure long-term stable operation and provide lasting protection for your electrical system.
4. Smart Meters & Energy Monitoring
TOMZN’s smart energy meter supports real-time power consumption monitoring and is an ideal tool for energy audit, billing transparency and energy-saving optimization. It is compatible with single-phase and three-phase systems and provides DIN rail installation for easy integration into the distribution box.
