| Long specification | Three-pin surge protection according to the requirements of Class III in accordance with IEC 61643-11, EN61643-11:2013. The arrester serves as surge protection and is used in applications in accordance with IEC 61643-12. The arrester is installed in a standard installation/distributor housing in the vicinity of the equipment that needs protection. The VPU III 3 280 V is earthed between the outer conductors (L1, L2, L3 and the neutral conductor). With thermal separation device on the varistor. If there is no longer any protection, the colour of the LEDs changes from green to red. The functional state is also displayed by a voltage-free signalling contact (NC contact).
