The Legrand surge protection combination device T1+2 7.5 kA is a highly advanced protection device specifically designed for use in TT and TN-S systems. It provides comprehensive protection against surges that can be caused by indirect lightning strikes or switching actions. With a nominal voltage of 230/400 VAC and a lightning impulse current of 7.5 kA per pole, this combination device is ideal for facilities and buildings that do not have external lightning protection. The spark gap base ensures reliable performance, while the integrated remote signaling contact and voltage tapping at L1 allow for easy monitoring and integration into existing systems. The combination device meets the requirements of the IEC/EN 61643-11 standard, making it a safe choice for surge protection.
