Surge Arresters
Products for protecting equipment in low-voltage power systems against atmospheric and switching overvoltages.
Limiter series PROTECT
We are the only company on the market to offer a complete set – a limiter + a dedicated PROTECT clamp. You gain compatibility, a certified product, and time savings.
Application:
PROTECT series surge arresters are designed to protect devices in low-voltage power networks against direct and indirect atmospheric overvoltages, as well as switching overvoltages.

The PROTECT series surge arresters are designed to protect devices in low-voltage power systems against direct and direct atmospheric overvoltages and switching overvoltages.
Application:
They are used to mount surge arresters on insulated or bare insulated low-voltage lines.
| A | Straight line clamp for bare wires 16-120 mm² |
| B | TI PROTECT Insulation piercing clamp for Al/Cu insulated wires 16-120 mm² |
| C | TTDI PROTECT Double-sided insulation piercing terminal: main line Al/Cu 16-120 mm², insulated branch Al/Cu 16-95 mm² |
| D | TNDI PROTECT Single-sided insulation piercing terminal: main line insulated AL/Cu 16-120 mm²; bare branch Al 16-120 mm² |
| E | F-type terminal – insulated wire 16mm² – 230 mm (pipe). Works with insulation-piercing terminals. |
| F | G-type terminal – terminal for direct connection of the arrester to the transformer. |
| G | H-type clamp – clamp for direct connection of the arrester to a TOGA-type clamp. |
| H | Type P cable – flexible copper with a cross-section of 10 mm² insulated, 700 mm long with a Ø 8 mm eyelet terminal for connection to an earthing terminal. |
