Type 1 + 2 lightning arrester SLS-B+C50/3+1

combinedplug-inlow-voltage

Lightning and surge arrester for three phase lines (3F+N) 230/400 V. Combined type 1 and 2 (Class B + C) protector, suitable for protection of low voltage lines against lightning strikes and surges up to 50kA (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. Characteristics • Three phases protector (3-poles + NPE). • 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.
