MOSIPO 15/690
| Name | Low voltage Surge Arrester |
| Type | MOSIPO 15/690 |
| Product | MOSIPO is a low voltage metal oxide surge arresters with silicone coating. They are designed to be installed in LV power lines or in junction boxes up to 1 kV as the first level of protection against direct lightning strikes |
| Code (l = 0,5 m) | 20 66 27 |
| Code (l = 1,0 m) | 20 66 32 |
| Characteristics | The disconnecting device reacts after a certain number of strokes when in normal operation the current through the surge arrester increases over 1 mA or in case of atmospheric discharge (current bigger than 65 kA). |

The position for installing NNO and MOSIPO surge arresters is decided by
directives and technical regulations. They must be installed:
- on all branches and ends of low voltage overhead power lines,
- at a maximum mutual distance up to 1000 m,
- at a distance smaller than 500 m, where storms occur more often,
- in all passages from free conductors to cables and vice versa.
