Surge arrester V20-3+FS-275 T2 275 V, TN-C

The V20-3+FS-275 is a Type 2 surge protective device (SPD) designed to protect electrical installations against overvoltages caused by switching and lightning impulses. The device is suitable for use in a TN-C network and is installed on a DIN rail in an electrical distribution board.

The surge protective device features pluggable modules, a visual status indicator, and a remote signaling output. This allows the operational or fault status of the device to be checked visually in the distribution board and, if necessary, enables the signal to be transmitted to a control or monitoring system.
