In today’s frequent electrical safety accidents, a leakage protection plug that can cut off the current within 0.1 seconds may be the last line of defense to protect the safety of household and enterprise electricity. Yuyao Zhongjian Electric Co., LTD., with 20 years of technology, concentrated this key protection technology in the square inch, to create a global market trust leakage protection plug solution.

【 Technical analysis: Triple protection, as fast as milliseconds 】

The leakage protection plug of Zhongjian Electric takes “prevention-response-block” as the core design concept:

Intelligent monitoring layer: Built-in high-sensitivity sensor chip, real-time monitoring of abnormal current fluctuations, accurate identification of leakage current in the range of 5mA-30mA;

Ultra-fast response layer: electromagnetic trip technology is used to automatically cut off the power supply within 0.1 seconds of detecting the leakage signal, far exceeding the industry standard (the response time of conventional products is about 0.2 seconds);

Physical protection layer: the shell is made of V0 flame retardant material, and the sleeve is made of phosphate-bronze nickel plating process, which is resistant to corrosion and wear, and can pass 8000 violent insertion and removal after testing.

Through the rigorous testing of UL and VDE, the product can still operate stably in extreme environments such as high temperature (70℃) and high humidity (95%RH), becoming a “security guard” for home, medical equipment and outdoor engineering scenes in Europe and the United States.

【Scene Empowerment: Global protection from home to industry】

Family scene: For the risk of children’s miscontact, the plug is equipped with a safety door design, a single hole needs more than 75N strength to open, with LED fault indicator, intuitive prompt circuit abnormalities;

Industrial scenario: Develop IP67 waterproof and dust-proof version, which can cope with harsh environments such as mines and ports, and cooperate with 30A large current carrying capacity to ensure stable operation of heavy equipment;

Business scenario: Provides customized modules for hotels and data centers, supports remote leakage alarm function, and seamlessly connects with intelligent management system.

【Quality Endorsement: The core logic behind Global Certification】

Each leakage protection plug needs to undergo 20 tests before leaving the factory:

Destructive test: 10 meters high drop, 200kg pressure impact;

Durability test: -25℃ to 100℃ temperature difference cycle, salt spray corrosion for 96 hours;

Functional test: simulate extreme conditions such as lightning surge, overload and short circuit.

The testing center of the company is equipped with oscilloscopes imported from Germany and high-precision leakage current generators from the UK Clair to ensure that the products are 100% in line with the standards of exporting countries. Through ROHS environmental protection certification, eliminate heavy metal pollution, so that safety and environmental protection counterparts.

【Cooperation value: not only products, but also service ecology】

Zhongjian Electrical provides “technology + certification + after-sales” three-dimensional support for partners:
✅ Custom development: Support voltage (100V-250V), plug system (US/EU/UK standard, etc.) flexible adaptation;
✅ Certification agency: relying on mature experience, to help customers quickly obtain the target market access qualification;
✅ Cloud management: The Internet of Things module is optional to monitor the power consumption health status of the equipment in real time.

“Our goal is not to sell plugs, but to make every electrical terminal a node in a secure network.”
