Interface characteristics
Rated & operational voltage (Un / Ue)
230V a.c. 50Hz
Rated insulation voltage (Ui)
320V a.c. 50Hz
Rated impulse withstand voltage (Uimp)
4kV
Rated current of the Assembly (InA)
100A, 63A, 40A
Note: Dependent upon rating of main incoming device
Rated current of an Outgoing circuit (Inc)
MCB 6A - 63A (marked rated current on device)
RCBO 6A - 50A (marked rated current on device)
Rated current of outgoing unit (Inc)
RCCB 40A -100A (marked rated current on device)
Rated conditional short-circuit current of the ASSEMBLY (Icc)
Annex ZB: 16 kA rms at 250V, power factor 0.6 with equipment and arrangements specified in Hager’s technical documentation /
catalogue.
Protection against electric shock
Consumer unit shall be installed in an electrical system conforming to the current edition of IEC 60364 / BS 7671
Rated diversity factor (RDF) / Values of assumed loading
1way = 1.0
2way – 3way = 0.8
4way – 5way = 0.7
6way – 9way = 0.6
10way and above = 0.5
Note: RDF only applies to continuously and simultaneously loaded
circuits.
In principle, this means adjacent circuit-breakers having a load
‘on’ time exceeding 30 minutes or where a load not exceeding 30
minutes has an ‘off’ time less than the ‘on’ time, will need to have
the rated diversity factor applied as indicated.
Rated frequency (fn)
50 Hz
Pollution degree
2
Types of system earthing for which the ASSEMBLY is designed
TNC-S, TN-S when installed in an electrical installation complying with BS 7671
Hager recommends for TT systems a 100A type S time delayed RCCB or a main switch with RCBO protection only on all outgoing circuits.
Indoor use only
Stationary ASSEMBLY
Degree of protection
IP2XC with Door Open / closed and full compliment of outgoing devices and or blanks fitted.
Note: Where cables are installed through top wall of enclosure, gaps of IP4X to be maintained.
Intended use
Intended for use in domestic (residential) or similar premises.

EMC Environment B
External design
VC & VH: Wall-mounted, surface type, enclosed assembly.
Mechanical impact protection
IK 05
The type of construction
Fixed parts
Type A DBO (Distribution board for use by ordinary persons)
