Surge arrestor V20 in 550 V, type 2
Surge arrestor V20, 1-pole, 550 V
Surge arrestor, type 2
• For surge voltage protection equipotential bonding to VDE 0100-443 (IEC 60364-4-44)
• Discharge capacity to 40 kA (8/20) per pole through high-performance varistors
• Modular connectable arrestor with dynamic cut-off unit and visual status display
• Locking mechanism with vibration protection and voltage keying
• Halogen-free plastic (UL 94 V-0)
• The remote signalling variants (FS) have a potential-free changeover contact for remote signalling
Application: Equipotential bonding in main and sub-distributions.
