The Surge Arrester -BT PUM 3WY 208 RM/3P is a high-performance surge protection device designed for 208V three-phase electrical systems. It effectively protects sensitive equipment from voltage surges, transients, and spikes caused by lightning or power fluctuations. Featuring a modular design, the arrester ensures quick maintenance and easy upgrades. The "BT" indicates electrical isolation, preventing noise interference, while "PUM" refers to its surge protection module, offering rapid response to transient voltages. With 3P (three-pole) protection, it covers all conductors—live, neutral, and ground—ensuring comprehensive protection for industrial and commercial applications. Ideal for high-voltage environments.
Surge Arresters for Electrical Systems -BT PUM 3WY 208 RM/3P
The Surge Arrester -BT PUM 3WY 208 RM/3P is a robust surge protection device specifically designed for 208V three-phase electrical systems. It effectively shields sensitive equipment from damaging voltage surges, transients, and spikes caused by events such as lightning strikes, switching operations, or grid fluctuations.
Key Features:
BT (Electrical Isolation Type): This arrester provides electrical isolation to prevent the transmission of electrical noise and interference within the system, ensuring the protection of sensitive devices. PUM (Surge Protection Module): The surge protection module (PUM) offers fast response times to transient voltage events, absorbing high-voltage surges and protecting connected equipment. 3WY (Three-Wire Configuration): Designed for three-phase systems with a three-wire configuration, providing comprehensive protection to the live, neutral, and ground conductors. RM (Modular Design): The modular design allows easy installation, replacement, and maintenance, offering flexibility and long-term reliability. 208V Rating: Ideal for 208V electrical systems, commonly used in industrial, commercial, and large residential setups. It ensures maximum protection against overvoltage conditions.
Applications:
Industrial Facilities: Protects manufacturing equipment and machinery from power surges and electrical faults. Commercial Buildings: Safeguards HVAC systems, lighting, and other critical infrastructure from electrical damage. Power Distribution Systems: Offers reliable surge protection for electrical grids and distribution panels.
Working Principle:
Surge arresters typically operate using either a spark gap or voltage-limiting technology. When the voltage exceeds a predefined threshold, the surge arrester quickly conducts, directing excess electrical energy to the ground or a safe path, preventing overvoltage from reaching sensitive equipment in the electrical system. Technical Specifications: Rated Voltage: Available in various voltage ratings to meet application-specific needs. Discharge Current: Offers a range of discharge current ratings to accommodate different system requirements. Response Time: Less than nanoseconds, ensuring immediate protection. Durability: Designed with high voltage withstand capability to handle repeated surge events. Operating Temperature: Suitable for various environmental conditions, typically ranging from -40°C to +70°C.
