MCCB circuit breaker WLM6-800A-3300 3P/4P WLM6 Series thermal magnetic type breaker 400V/690V 800 amp 3/4 Poles
MCCB Highlights
Thermosetting insulating materials
1. The unique formula material is adopted, which has high strength, good arc resistance, strong insulation, high temperature resistance and good flame retardancy
2. High sensitivity temperature sensor
High quality bimetallic element materials are used, and there is no need to reduce the capacity from -5℃ to 55℃
3. Spring materials with longer temperature resistance and fatigue resistance (50% longer than ordinary springs)
These materials are typically composed of resins such as epoxy, phenolic, and silicone, which are combined with reinforcing materials such as fiberglass or aramid fibers to enhance their mechanical strength and thermal stability. This results in insulation that can withstand high temperatures, mechanical stress, and environmental factors, making them suitable for use in demanding electrical environments.
In terms of safety, thermosetting insulating materials are designed to provide excellent electrical insulation properties, effectively preventing the flow of current and minimizing the risk of electrical faults. Additionally, these materials exhibit high resistance to fire, chemicals, and moisture, further enhancing the safety and reliability of electrical systems in which they are used.
Furthermore, thermosetting insulating materials are engineered to comply with international safety standards and regulations, ensuring that they meet stringent performance and safety requirements. This provides users with the confidence that their electrical systems are protected by insulation materials that have been rigorously tested and certified for safety and reliability.
In conclusion, thermosetting insulating materials are distinguished by their high-quality components, exceptional electrical insulation properties, and compliance with industry standards, making them a trusted choice for ensuring electrical safety and reliability in a wide range of applications.
