Description
The ZPAC1-13VG-30-275 is a space-saving, plug-in Type 1+2+3 SPD designed for 230/400 V three-phase systems and installation on 40 mm busbar systems. Integrating CITEL VG technology (MOV + gas-filled spark gap), it combines all three protection classes in a single device to provide robust surge protection for downstream equipment and meets the minimum Type 1 lightning current requirements (Iimp 12.5 kA, 10/350 µs). Its design allows use in buildings requiring lightning protection classes III and IV and enables installation in the pre-metering area where applicable. The modular plug-in concept simplifies on-site maintenance and replacement, reducing downtime for electrical contractors and facility managers.
