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

The V20-3+FS-275 is a Type 2 surge protection device, or 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 mounted on a DIN rail in an electrical distribution board.

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