Type 1+2+3 DACN1-25CVGS surge arresters provide effective protection for low-voltage networks against original surges. Based on VG technology, they guarantee high flow capacity (Iimp 25 kA) without leakage current, and optimized TOV resistance. Compact and monobloc, they integrate a thermal disconnector, a mechanical indicator and a remote signalling output, offering a reliable and durable solution for electrical installations. The SC version also incorporates an overvoltage meter.
