Circuit Breaker
Low voltage circuit breaker(ACB)
Product Introduction
Air circuit breaker, also called universal circuit breaker, is suitable for AC 50Hz/60Hz, with rated current of 200 A ~ 7500 A, rated isolation voltage of AC1000V/1250V, rated working voltage of AC220/230/240V, AC380/400/415V, AC440/480V, AC660/690V, etc. At the same time, it also has isolation function. Circuit breakers have multiple protection functions, which can not only achieve high-precision selective protection, but also avoid unnecessary sudden power failure and improve the reliability and safety of power supply system.
Product Model
According to different authorized companies, the main models of products are Blockset, 8PT and Mdmax.
Product Features
High efficiency arc extinguishing and breaking. The arcing chamber of circuit breaker adopts the principle of air blowing and magnetic blowing to extinguish arc, optimizes the design of arcing grid, increases the driving force for arc and improves the breaking ability of products.
High electrical life and short-term tolerance. The body design adopts high-strength reinforced molded plastic, which has extremely high impact strength and insulation characteristics. The design of arc contact structure improves the electrical life of the product; The contact system and operating mechanism are greatly optimized, and the strength of metal structural parts is higher, and the compensation of contact pressure is realized, which improves the reliability and short-term tolerance of products.
The controller has complete types and diverse functions. The controller can be displayed by digital tube or LCD screen, with measurement and protection functions, multiple current protection functions, maintenance functions and remote reset device.
Integrated communication network. The communication interface can be configured to realize the four remote data transmission functions of telemetry, remote control, remote adjustment and remote communication.
In special use areas, there are special types such as AC 1140V circuit breakers, damp-heat circuit breakers and wind power plateau circuit breakers.
Applicable Conditions
1. Ambient temperature:-25℃ ~+70℃ (special ambient temperature can be customized);
2. Altitude: The altitude of the installation site is not more than 2,000 m, so users at high altitude need to reduce their capacity.
3. Atmospheric environment: the relative humidity shall not exceed 50% at +40℃ and 90% at +20℃;
4. Earthquake intensity: no more than 8 degrees;
5. The product is installed in a medium without explosion danger, and the medium is not enough to corrode metals, gas and conductive dust that damage insulation, and avoid being used in places where rain and snow attack;
* Please consult with our company when it is used beyond the above-mentioned conditions.
