Phoenix Contact 2800184 VAL-MS-T1/T2 335/12.5/3+1 Lightning/surge arrester type

The Phoenix Contact VAL-MS-T1/T2 335/12.5/3+1 is a universal varistor-based plug-in lightning and surge arrester for 3-phase TN-S and TT power supply networks with separate N and PE conductors (5-conductor system: L1, L2, L3, N, PE). Combining Type 1 and Type 2 protection per IEC/EN, it delivers 12.5 kA impulse discharge current (10/350 µs) per L-N and L-PE position, qualifying it for Lightning Protection Levels III and IV. The pluggable DIN rail module features optical fault signalling and vibration-resistant latching for reliable long-term service.
