SLS-C20

SURGE PROTECTION

 

  • Type 2 protector (class C), suitable for the protection of low voltage lines against transient surges up to 20 kA (8/20) in TT (TNS) networks.

  • Recommended for industrial installations, switchboards, buildings with low risk of lightning strike or buildings powered by underground electrical lines.

SLS-C20/1+1

Transient surge arrester for single-phase (F+N) 220 V lines.

Type 2 arrester (class C), suitable for the protection of low voltage lines against transient surges up to 20 kA (8/20) in TT (TNS) networks.

Recommended for industrial installations, distribution switchboards, buildings with low risk of lightning strike or buildings powered by underground lines.
