SLS-B+C50/1+1
SURGE ARRESTER
Lightning and surge arrester for single phase lines (F+N) 230 V.
Combined type 1 and 2 (Class B + C) protector, suitable for protection of low voltage lines against lightning strikes and surges of up to 25kA (10/350) in TT (TNS) networks.
Recommended for industrial facilities or buildings, with a risk of partial lightning currents, induced overvoltages during a lightning strike or switching overvoltages.
FEATURES
- Single phase protector (1 pole + NPE).
- It provides high protection and low residual stress, for its combination of high performance varistors and encapsulated spark gap.
- Easily replaceable plug-in modules with locking system.
- Base and modules configured for secure mounting.
- Easy maintenance through local fault locator.
