Ինչպես ընտրել RCCB-ի ճիշտ զգայունությունը

2025 թվականի սեպտեմբերի 26-ին

The right RCCB sensitivity depends on where it will be used and what level of protection is needed. In general, 30mA RCCBs protect people from electric shock, while 100mA or 300mA RCCBs are better for equipment and fire protection. What is the purpose of RCCB application? An RCCB (Residual Current Circuit Breaker) is designed to trip when it detects leakage current. Unlike MCBs that guard against overloads, RCCBs prevent electrocution and reduce fire risk. They are essential for both residential and industrial systems. What is the difference between 30mA vs 100mA RCCB? The key difference between 30mA vs 100mA RCCB is the balance between human safety and operational stability: If your RCCB keeps tripping unexpectedly, the cause may be a sensitivity mismatch. For more details, review common RCCB tripping issues. When should you use a 30mA RCCB? A 30mA unit should be used when the primary concern is direct human protection. It is ideal for: This sensitivity reacts quickly to small leakage currents that could otherwise cause dangerous shocks. When should you use a 100mA or 300mA RCCB? For industrial buyers, 100mA and 300mA are more practical: RCCB Sensitivity Comparison Table Sensitivity Primary Use Protection Level Typical Application 10mA Very high risk areas Extreme human protection Swimming pools, medical equipment 30mA Residential & commercial Human protection Homes, socket outlets, kitchens, bathrooms 100mA Industrial circuits Mixed: some human, mainly equipment/fire Factories, machinery-heavy lines 300mA Fire & equipment Fire protection Upstream distribution boards, large installations This comparison makes it easier to select the right sensitivity based on […]

Industrial AC contactor devices switch motors, HVAC equipment, and lighting systems on and off automatically. These electromagnetic switches prevent equipment damage and enable remote operation of high-power electrical loads. Industrial control devices provide safe automation capabilities in manufacturing environments. What Is an Industrial AC Contactor? An industrial AC contactor is an electromagnetic switch that controls high-current electrical circuits. Motor starter contactor applications handle industrial motor control requirements. These devices manage currents from 10A to several hundred amperes. AC magnetic contactor operation uses electromagnetic coils to move contacts. When energized, the coil pulls contacts together to complete circuits. When de-energized, contacts separate to break circuits. Contactors have advantages over manual switches. They allow remote operation from control rooms. Industrial control devices enable automated system integration and safer equipment operation. Hero Product Highlight Professional AC Contactor Manufacturer The High-Quality and Low-Cost Solution for Your AC Motor Switching and Protection Needs View Product Why Do Motors Need Contactor Control? Motor starter contactors are essential for protecting motors from damage during startup and operation. Motors draw high inrush current when starting that can be 6-8 times their normal running current. Standard switches cannot handle these current spikes safely. Motor starter contactors provide controlled starting by handling inrush currents and protecting downstream equipment. They also enable remote motor control from control panels or automation systems. Remote control prevents operator exposure to high-voltage equipment. Key motor control benefits include: TOSUNlux AC unit contactor models provide reliable motor control with current ratings up to 95A for industrial applications. What Are the Main […]

Solar PV system protection uses circuit breakers, fuses, and surge protectors to stop equipment damage from electrical faults. These devices keep solar systems safe and prevent expensive repairs. Why Do Solar PV Power Systems Need Protection? Solar panel protection prevents damage to photovoltaic systems from electrical faults and voltage surges. What does PV stand for in solar power? PV stands for photovoltaic, which converts sunlight into electricity. The sequence of operation photovolatic system starts with solar cells making DC power. This power flows through strings and arrays to inverters that change DC to AC. Each stage needs protection. Solar power circuit protection differs from regular electrical systems. Solar systems use high DC voltages up to 1500V with low fault current. Regular electrical devices cannot handle these conditions. Protection devices must comply with IEC standards and prevent equipment damage from lightning strikes or electrical faults. What Are the Main Types of Solar Circuit Protection? Solar PV systems require DC protection for high-voltage arrays and AC protection for grid connections. Each side handles different electrical characteristics and fault types. Key protection points include: TOSUNlux DC circuit breakers handle up to 6000A breaking capacity for commercial solar arrays. How Do DC Circuit Breakers Work in Solar Systems? DC circuit breakers handle the specific requirements of solar DC circuits. These devices must interrupt DC current without the natural zero-crossing that helps AC breakers extinguish arcs. TOSUNlux TSB5-63DC Circuit Breaker has a modular design with breaking capacity up to 6000A and rated voltage of 800V. It offers 1P, 2P, 3P, […]

What International Certifications Should Low-Voltage Electrical Products Have for Global Market Access?

2025 թվականի սեպտեմբերի 26-ին

Low-voltage electrical products require certifications such as CE, CB Scheme, UL, and VDE to ensure safety and compliance with global trade standards. This not only builds consumer confidence but also ensures regulatory compliance and gives manufacturers the opportunity to expand into new markets. Why Do Low-Voltage Products Need Certification? Certifications prove that electrical products meet safety, performance, and quality standards. They protect users from risks such as short circuits, fire, or malfunction. For manufacturers, certifications: For a broader overview of certification systems, check out 5 Major International Certification Bodies. CE and UL certifications are essential for safety and global market access. What Is CE Marking and Why Is It Important? CE marking is mandatory for all electrical products sold in the European Economic Area. It shows compliance with EU directives for safety and environmental protection. Without CE, products cannot legally enter the European market. For example, Tosunlux’s CE-certified low-voltage circuit breakers meet EU standards for safety and performance. Learn more in The Importance of CE, CB, and VDE Standards. CE marking ensures that low-voltage electrical products meet EU safety and environmental standards. What Is the CB Scheme? The CB Scheme, run by the International Electrotechnical Commission (IEC), helps manufacturers gain approval in multiple countries with a single test. Instead of repeating certifications in each country, one CB report can be accepted by many national bodies. This saves both cost and time. Tosunlux’s modular devices and distribution boxes are examples of products that can benefit from CB Scheme approval for multiple market entry. The CB Scheme […]
