Product Description

Product Description

^{Product Overview}

    ARM5 series plastic case circuit breaker (hereinafter referred to as circuit breaker) is the latest new product developed by our company. Its design reflects the latest current limiting principle and manufacturing technology, and has the characteristics of small and compact, modular, high breaking, zero flying arc, green and environmental protection. The circuit breaker is suitable for connecting, breaking and carrying rated current in circuits with dry AC 50Hz/60Hz, rated insulation voltage of 1000V, maximum rated working voltage of 690V, rated current of 32A-630A, and can provide reliable protection for lines and power-using equipment in case of overload, short circuit and under-voltage. It can also be used as infrequent starting and overload, short-circuit and under-voltage protection for motors. The circuit breaker can be installed vertically (i.e., vertical installation), horizontally (i.e., horizontal installation), and also down into the line. The circuit breaker has an isolation function and its corresponding symbol: "".

Main functions and features

Pneumatic protection device

In case of short circuit and large current in the circuit, the gas in the contact unit box will be rapidly pressurized, and the pneumatic protection device will quickly pull the operating mechanism to lock under strong air pressure, greatly reducing the damage of short circuit current to other electrical components and buses.	Magnetic blowout design: the current flows through the fixed contact to generate an electromagnetic source, which forms an annular magnetic field with the iron core. The arc quickly enters the arc extinguishing chamber under the action of the magnetic field, which is conducive to quickly break the current.
The reasonable structure design of moving and fixed contacts makes the short circuit peak value and energy I²t in the protection circuit of this series of products far less than the expected value.
Working principle: the current flows in from the fixed contact    1, flows out from the fixed contact    2 through the moving and fixed silver contact and the moving contact. The moving contact quickly disconnects under the action of strong electric repulsion force (Holm force and Lorentz force) to improve the breaking speed.
Air blowing design: when short circuit and large current occur in the circuit, gas producing parts produce gas under the high temperature of the arc, the air pressure in the contact unit box increases rapidly, and high-speed air flow can be formed through the air outlet of the arc extinguishing chamber, which can effectively extinguish the arc.

A: We have not worked directly with foreign customers before, we provide ODM and OEM services for brands in China and then they take our products and sell them to foreign customers, basically to Europe and the Middle East.
11,Q: Your products are really good, but we have seen the same circuit breakers on the market nearby and their prices are much cheaper than yours.
A: First of all, I would like to emphasise that the price is definitely proportional to the quality. If you are a buyer, you must know that the materials and treatment processes used in our products are better than those of our peers, and the quality is recognised in the same industry. Our factory has a thermosetting workshop, thermoplastic workshop, welding workshop, hardware stamping workshop and assembly workshop, and the rate of self-made parts is as high as 80%. We have also built a new factory in Wuhu to guarantee the supply of parts for us, so that the parameters and various technical indicators such as mechanical life, Icu, Ics, etc. are very stable, and the match between parts is very high, and the service life of the finished product is also very long, which is They can be used in high-end industrial areas and hospitals, where the quality of the circuit breakers is very high. We also have our own technology patents and a very professional R&D team of 30-40 engineers to respond to the various needs of our customers, the development cycle of new products only takes 30-40 days, in the process, unconditionally provide you with technical expenses, we can greatly reduce the cost of communication and research and development costs. if particularly urgent, I can apply to my superiors to set up a customer line for you, specifically for you to assemble MCCB.
