Arm1l Series Residual Current Protected Circuit Breaker 4poles 250AMP RCCB

Product Description

Product Description
Product Overview
Residual current circuit breaker, mainly applicable to AC 50Hz, rated voltage 400V, rated current up to 800A in the distribution network, used to provide indirect contact protection to people, can also be used to prevent fire hazards caused by equipment insulation damage, resulting in ground fault current, and can be used to distribute electrical energy and protect the line and power supply equipment overload and short circuit, but also as the line of infrequent conversion and motor Infrequent switching and motor starting. Conventional leakage protection module with residual current protection circuit breaker work power sampling for two-phase, this series of circuit breakers for three-phase, if the lack of a phase, circuit breaker leakage protection module can still work normally; rated residual action current and maximum disconnection time according to the actual situation on site adjustable; when the phase voltage is reduced to 50V, leakage protection module can still work normally

Envirinment of use
1. The installation site should be free of conductive dust, corrosive gases, flammable and explosive gases, and rain and snow.
2. Elevation ≯ 2000m.
3. Ambient temperature -5ºC~+40ºC, maximum daily average temperature≤+35ºC.
4. Relative humidity ≤ 50% (when the ambient temperature is +40ºC).

FAQ
1.Q: Are you trading company or manufacturer ?
A: We are manufacturer and specializing in manufacturing good quality of MCCB.
2.Q: How long is your delivery time?
A: Normally 5-10 days if there are goods in stock. Or it will take 15-20 days. For customized items, the delivery time depends.
3.Q: What is your terms of payment ?
A: 30% T/T in advance ,and the balance before shipment.

4.Q : Can you make customized products or packing?
A: Yes.We can offer customized products and packing ways can be made according to customer's requirement.
5.Q: Can you offer mould making services?
A: We have made many mould for different customers for years.Wecan offer DMC Thermosetting Compressionmoulding,Thermoplastic injection moulding,Metal stamping moulding.

10.Q: What are the countries you have exported to?
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.
