distribution box

distribution box
Number: LK-DBCTB030-1
  • Product introduction



 Outdoor Distribution Boxes for Krone Modules are highly versatile. There are three compact sizes with variable depth and is designed for surface or flush mounting. With just a few components, a high degree of flexibility is achieved at low inventory costs. The Krone Type DP boxes are made of polystyrene, a self-extinguishing plastic which ensures corrosion-free, highly impact-resistant, stable and maintenance-free use.

Technical characteristics

Characteristics of the contact connection
Connector of the distributive wire


Range of the section:

diameter 0,4… 1,2 mm

Diameter on the isolation:

it is maximal 5 mm

The current-response characteristics:

20 A(10 A on each conductor) during not less than 10   min, without the deformation of the module

Note: if is required resistance to the flow of current   from 20 A to 30 A, this is ensured by the application of gas-discharge   arresters of different types

Insulation resistance

“Dry” atmosphere:

> 10 12 Ohm

“Moist” atmosphere (standard ASTM Of d618, procedure   F):

> 10 12[Om]

Salt fog: (standard ASTM Of b117)

> 10 10 Ohm

Immersion beside the water: (15 days before 3% solution   Of naCI)

> 10 10 0[m]

The contact resistance

R of material + R of the contact cross connection + by   R of the contact connection of the wires

< 10 m

Increase in the contact resistance

After climatic testings:

<2,5 m 

After 50 connections - turning offs:

<2,5 m
