Features:
• Upstream Installation Design: Mounts directly before protected equipment for maximum surge suppression efficiency.• High Surge Current Capacity: Capable of handling large surges from lightning strikes, utility switching, and fault events.
• Multi-Mode Protection: Protects line-to-line (L-L), line-to-neutral (L-N), and line-to-ground (L-G) pathways.
• Real-Time Status Indicators: Equipped with LEDs or monitoring displays to show operational and protection status.
• Automatic Disconnection: Shuts off power to downstream equipment during severe surge or fault conditions.
• Thermal Protection: Integrated thermal fusing safely disconnects the device if it overheats or fails.
• Durable, Weatherproof Enclosure: Rated for indoor and outdoor environments with resistance to dust, water, and corrosion.
• Wide Voltage Range Support: Available for single-phase, split-phase, and three-phase systems.
• Standards-Compliant Design: Tested and certified to meet international standards such as UL 1449, IEC 61643, and more.
• Compact and Versatile Form Factor: Fits into panels, cabinets, or enclosures with flexible mounting options.
Advantages:
• Prevents Equipment Damage: Blocks high-voltage surges before they reach sensitive or critical electrical systems.• Enhances System Reliability: Reduces unexpected shutdowns and operational failures caused by transient voltages.
• Extends Equipment Lifespan: Minimizes wear and degradation of components due to electrical stress.
• Reduces Maintenance Costs: Lowers the frequency of repairs and part replacements caused by surge damage.
• Increases Safety: Prevents fire hazards and electrical accidents with built-in thermal and fault protection.
• Ensures Compliance: Meets global safety standards like UL 1449, helping with regulatory and insurance requirements.
• Protects Across All Environments: Suitable for industrial, commercial, residential, and outdoor applications.
• Easy to Install: Integrates seamlessly upstream of the equipment without major system alterations.
• Maintenance-Free Operation: Delivers long-term protection without requiring regular servicing.
• Peace of Mind: Provides continuous, silent protection 24/7, even in harsh or unstable power environments.
Applications:
• Industrial Facilities: Protects PLCs, motor drives, control panels, and automation equipment from power surges.• Commercial Buildings: Safeguards HVAC systems, elevators, lighting, and office electronics from voltage spikes.
• Data Centers: Ensures uninterrupted operation of servers, switches, and storage systems.
• Telecommunications: Protects communication towers, base stations, and signal processing equipment.
• Medical Institutions: Shields sensitive devices like MRI machines, monitors, and diagnostic tools.
• Residential Applications: Guards smart appliances, entertainment systems, and home security devices.
• Renewable Energy Installations: Protects inverters, controllers, and batteries in solar and wind systems.
• Transportation Systems: Applied in traffic signal control, railway systems, and EV charging stations.
• Oil & Gas Sites: Used in remote, hazardous environments to protect control and monitoring systems.
• Utility Infrastructure: Installed at substations, transformers, and distribution panels to defend entire power networks.
