Lowvoltage arrester device designed to protect DC systems from lightning strikes and transient overvoltage. Reliable, durable, and simple to install for fast, effective protection. Key benefits Stable performance: Engineered from quality materials for consistent operation and a longer service life, reducing maintenance and replacement frequency. Effective protection: Guards electrical systems and onload electrical equipment against fulmination (lightning) and transient overvoltage events to minimize downtime and equipment damage. Easy installation: Designed for straightforward mounting and wiring so technicians can install the unit quickly and securely. Clear compatibility: Specifically designed for DC 420V 40KA applications—use only with systems matching this rating to ensure correct protection. Important attributes Function: Surge arrester that diverts and absorbs surge energy to protect downstream DC equipment. Compatibility: Low voltage arrester device with rating DC 420V 40KA. Material & performance: Built from durable, quality materials to provide stable discharge performance and extended operational life. Installation: Compact footprint and standard terminal connections support typical installation workflows (follow local electrical codes and installer instructions). Practical use scenarios Residential DC protection: Protect household DC circuits and onload devices in homes with DCpowered equipment rated to DC 420V 40KA. Battery and inverter systems: Safeguard battery banks, inverters, and DC control equipment from transient overvoltage on the DC side. Small commercial DC installations: Provide surge protection for DCpowered control and monitoring equipment in light commercial settings. Safety note: Install and the arrester according to applicable electrical standards and manufacturer instructions. Use only in systems that match the DC 420V 40KA rating.
