The values indicated refer to the ambient temperature of 25° C
and an interior temperature of 55° C.
For the nominal load factor the square dependence of the power
dissipation from the current shall be taken into consideration.

Mi-distribution boards comply with the requirements for
type-tested switchgear and controlgear assemblies (TTA)
in accordance with IEC 60 439-1/EN 60 439-1.
Type-tested switchgear assemblies are switchgear and controlgear
assemblies which are assembled and wired according to
manufacturer data without essential deviations from the original
type or system.
To meet these requirements for Hensel Mi Distribution boards,
the following must be noted:
1. The switchgear must consist of the type-tested enclosures
documented in this list.
2. The wiring of the equipment must be carried out with the
cross-sections and conductor types indicated in Table
„Rating of insulated conductors in switchgear assemblies“,
Index Technics, page 212.
3. Once the switchgear is completed, a routine test must be
carried out in accordance with this standard.
4. The test must be certified with a test report.
5. The switchgear must be provided with a manufacturer’s
identification mark.
Compliance with important data such as
- limit of temperature rise
- dielectric strength
- short-circuit withstand capacity
- short-circuit withstand capacity of the PE conductor
- IP degrees of protection
- creepage distances and clearances
is verified by type tests for this system.
Mi-distribution boards comply with the following standards
and requirements:
- IEC 60 439-1 / EN 60 439-1
Low voltage swichgear and control gear assemblies
- IEC 999 and EN 60 999
Safety requirements for screw-type and screwless-type
clamping units for electrical copper conductors
- EN 50 262
Metric threaded cable glands for electrical installations
- IEC 269
Low voltage fuses
- DIN 43 880
Built-in equipment for electrical installations;
overall dimensions and related mounting dimensions
- IEC 60 529
Degrees of protection provided by enclosures (IP-Code)
