L 13/40 230 ff 4 is a ready to install assembly of four voltage limiting SPDs providing four modes of protection, typically installed at the origin of the installation (e.g. in the Main Distribution Board (MDB)) for three-phase plus neutral 230/400 V TN-systems, with the following features and benefits:

Impulse test classification: Test class I and II / Type 1 and 2 (according to IEC/EN 61643-11);
• L 13/40 230 ff 4 is a voltage limiting SPD for the protection of low voltage installations and equipment against direct and indirect lightning effects;
Backup protection is not required with an upstream MCB ≤ 125 A or up to an Isccr ≤ 4 kA rms;
Three colour Status Indicator with progressive indication of remaining performance.
