Low-voltage surge protector that prevents damaging electrical spikes and transient overvoltages in your home or small installation. Provides reliable defense for electrical systems and sensitive devices with a nominal discharge current of 20 kA. Key benefits Protects equipment and electronics: Limits dangerous overvoltages and spikes before they reach appliances, prolonging the life of home electronics and reducing risk of damage. Clear visual monitoring: Color-coded indicator shows status at a glance — green = operating normally, red = fault requiring attention for uninterrupted protection. Easy to install and integrate: Designed for straightforward connection to any air switch (circuit breaker) or outlet protection in your home, making it accessible for electricians and homeowners. Standards-compliant, dependable performance: Conforms to IEC/EN 61643 and operates on AC 50/60 Hz up to 385 V for consistent performance in typical low-voltage systems. What it does and why you need it Acts as the first line of defense against transient overvoltages caused by lightning strikes, switching operations, or utility disturbances. Protects both the distribution wiring and connected devices, reducing downtime and repair or replacement costs. The visual status indicator simplifies maintenance by signaling when the device needs inspection or replacement. Compatibility and practical attributes Function: Low-voltage surge arrester for protection against spikes and transient overvoltages. Compatibility: Connects to standard air switches (circuit breakers) or outlet protection devices in low-voltage residential and commercial installations. Performance: Nominal discharge current 20 kA; suitable for AC 50/60 Hz systems up to 385 V. Safety/standards: Built to IEC/EN 61643 requirements. Construction: Durable housing designed for reliable service in electrical distribution environments. Typical applications Home electronics protection: Install in the main distribution board to protect TVs, computers, refrigerators, and home entertainment systems from damaging surges. Home office and IT: Safeguard routers, NAS devices, and desktop equipment to prevent data loss and hardware failure. Small commercial or workshop installations: Protect sensitive control equipment, power tools with electronic controls, and POS systems from transient overvoltages.
