Surge arresters class B+C: %p99 /%

- They are dedicated to protecting LV power supply installations against the effects of induced and switching overvoltages.They can be installed in networks such as: TN, TNC, TNCS, TNS, TT.

- They should be used as both the first and second level of protection in floor boards and sub-distributions.The arresters should be installed at the points where the electrical installation enters the building.

- They provide complete protection of the electrical installation and the electrical devices supplied from it against the effects of part of the lightning current and other types of overvoltages.

- They reduce overvoltages and bring surge currents from both types of overvoltages - direct and indirect - to the ground.They also provide a two-stage level of protection.

- Provide effective protection for computers, electronics/home appliances, etc.

- They are equipped with a visual operation indicator (green - protection, red - no protection).

SURGE PROTECTORS ARE EQUIPPED WITH A VISUAL OPERATION INDICATOR:

• green – protection
