Zeliang Electric new generation of small circuit breaker: with Seiko technology to protect the safety of electricity to enable a new experience of intelligent life
In recent years, with the surge in the number of household appliances and the acceleration of the process of industrial and commercial electrification, the hidden danger of electricity consumption has become the focus of social attention. According to statistics, there are more than 200,000 fire accidents caused by circuit overload and short circuit in China every year, of which nearly 40% of the cases are directly related to circuit breaker response delay and protection failure. Traditional circuit breakers generally have two major pain points:
- Passive protection lag: the mechanical trip response time is more than 0.1 seconds, which cannot match the instantaneous protection needs of precision equipment;
- Insufficient intelligence: Lack of real-time status monitoring ability, it is difficult for users to sense circuit abnormalities in time;
- Short service life: the average mechanical life of the industry is only 4000 times, frequent tripping accelerates the aging of components, and lays secondary hidden dangers.
Second, [Product core value: "Safety +" series redefines circuit breaker standards
The small circuit breaker independently developed by Zheliang Electric builds a full-scene power safety defense line with the three core advantages of "ultra-speed protection, intelligent perception, and ultra-long life" :
0.02 seconds fast power off technology
- Adopt high-precision electromagnetic trip system, the response speed is increased to 5 times that of traditional products, and the circuit can be cut off at the moment when the short circuit current reaches the critical value to avoid fire caused by arc sparks.
- Laboratory measured data show that when the current exceeds 300% of the rated value, it can be broken within 20 milliseconds, far exceeding the 0.1 second standard required by the national standard.
Intelligent temperature control dual safety system
- Innovative integrated thermal magnetic dual trip module, through the bimetal plate and electromagnetic coil work together, accurately identify overload and short circuit faults
Overload protection: real-time monitoring of conductor temperature, when the temperature rises more than 85℃ automatic power off, to avoid the line insulation meltdown;
Short-circuit protection: millisecond response to more than 2000A large current impact, breaking capacity up to 6kA.
Built-in IoT extension interface (optional), can be connected to smart electric box to realize remote monitoring of mobile phone APP, automatic push warning of abnormal power consumption.
20,000 mechanical life certifications
The use of German silver-nickel alloy contact (contact resistance ≤0.5mΩ), with a strengthened spring mechanism, by the national electrical products quality supervision and inspection center test, mechanical life exceeded 20,000 times, compared with the national standard GB/T 10963.1-2020 specified value increased by 150%. The original contact anti-oxidation coating technology ensures stable performance under high humidity and salt spray environment.
Third, 【 Technological innovation decoding: Core technology creates security barriers
Patent technology matrix support
The core patent group covers the three major fields of trip mechanism, arc extinguishing system and material process, including:
Double breakpoint breaking technology: the arc energy can be reduced by 60% through the two-way arc pulling design;
Three-dimensional arc extinguishing chamber (: using ceramic material and metal grid composite structure, breaking speed increased by 30%. Strict quality control system certification
- All products have passed Germany TUV Rheinland safety certification and China Compulsory Product Certification (CCC), and key production lines have introduced Siemens digital testing platform to achieve 100% full inspection:
Contact pressure test accuracy up to 0.01N
The opening and closing operation error is controlled within ±0.5ms.
Modular intelligent upgrade solution
Standard and intelligent versions are available:
Intelligent circuit breaker: built-in Bluetooth 5.0 communication module, can link Zheliang "electric Doctor" management platform, real-time display voltage/current/power curve, support peak and valley power optimization suggestions;
Docking compatible design: Reserved RS485 interface, suitable for new load scenarios such as photovoltaic energy storage system and charging pile
