At the same time, for preventing electric shock and fire, residual current circuit breakers play an important role in electrical safety. But if there are so many manufacturers, how do you choose technical compliant and reliable suppliers? This article looks at all aspects and provides a systematic selection guide for enterprises to make the best decision.
What is residual current circuit breaker?
Residual current circuit breaker (RCCB), also known as residual current device, is a safety device used to prevent electric shock and electrical fires.
It can quickly cut off the power supply in case of leakage in the circuit, protecting personal safety and equipment safety.
Working principle
The RCCB detects residual current in the circuit (i.e. the difference between the phase line current and the neutral line current) to determine whether there is leakage.
If the leakage current exceeds the preset value (30mA, 100mA), the circuit breaker will trip within milliseconds and cut off the power supply.
In the following video, I will explain to you the function of residual current circuit breakers
Why You Should Choose Wisely Manufacturers
1、 Technical parameters
Rated current and voltage range
Adaptation parameters should be selected according to the needs of the power distribution system:
Products with a rated current of ≤ 63A and a common geothermal low-voltage (220V/380V) voltage are usually needed for household or small commercial premises.
In addition, there are field situations like workshops and data centers that need high-performance circuit breakers rated at 630A and a breaking capacity of 50kA
For example, this RCCB product has a rated current of 16 amps and a voltage of 220V, which is suitable for households or small commercial places to protect the safety of current
Classification of residual operating current
Personal safety protection: Choose high sensitivity products with ≤ 30mA, suitable for direct contact protection
Equipment and fire protection: 100mA or 300mA, used for indirect contact protection or prevention of electrical fires
2、 Certification and Compliance
international certification
That means to check the conformity of the product with the international standards like IEC 61008 (RCCB) and IEC 61009 (RCBO) and the fulfillment of the market demand.
CE, UL and other industry certifications are also required for some products to ensure safety, reliability and compliance, enhance market competitiveness and customer trust.
Manufacturer Qualification Review
Verify whether the enterprise has ISO 9001 quality management system certification and production license
ONESTOP company has ISO 9001 quality management system certification and production license, and its products have certificates such as IEC 61008, CE, CCC, UL, etc. Is a trustworthy RCCB manufacturer
3.Product line and technological innovation capability
It is necessary to comprehensively examine the production capacity of selected manufacturers who require long-term cooperation to ensure expected market demand and a stable supply chain, so that they can guarantee continuous supply.
Secondly, they should pay attention to its research and development capabilities, whether there is a professional research team to constantly optimize and upgrade products to meet market changes and technological development, and thus improve the long-term cooperation value.
4、 Market reputation and after-sales service
User Evaluate
User evaluation consists of many aspects such as product quality, timeliness of delivery, and level of service, and is a significant reference for supplier selection. Suppliers are able to know the performance and effectiveness of the product in real use from users’ real evaluations, which are valuable reference information for future product improvement and optimization.
Especially customer reviews that have had actual collaboration with suppliers can more completely and objectively reflect the real level of the product. These reviews not only illustrate the advantages and disadvantages of the product in application, but also reflect the supplier’s performance in delivery and service. Therefore, such experience sharing has turned into a fundamental reference for enterprises to make new cooperation decisions, allowing them to choose credible partners, reduce cooperation risks, and ensure the smooth development and continued growth of business.
This is the customer’s genuine evaluation of ONESTOP products
After sales support system
ONESTOP provides fast response maintenance services and spare parts supply to ensure stable equipment operation. In addition,
all products come with a 2-year warranty, effectively reducing your long-term operation and maintenance costs, improving reliability, giving customers more peace of mind, and reducing additional expenses caused by malfunctions.
