Organization: IEC
Publication Date: 1 February 2005
Status: inactive
Page Count: 54
ICS Code (Conduits for electrical purposes): 29.120.10
scope:

This clause of Part 1 is replaced by:

This part of IEC 60670 applies to empty enclosures and parts of them for electrical accessories intended to be used with a rated voltage not exceeding 400 V and a total incoming load current not exceeding 125 A for household and similar fixed electrical installations, where a maximum capability to dissipate power in normal use is declared by the manufacturer.

These enclosures are intended for housing protective devices and devices with or without power dissipation. They are intended to be installed where the prospective short circuit current does not exceed 10 kA unless they are protected by current limiting protective devices with a cut-off current not exceeding 17 kA.

Enclosures complying with this standard are suitable for use, after installation, at ambient temperature normally not exceeding 25 °C, but occasionally reaching 35 °C over 24 h, max. 40 °C and min. -5 °C. An enclosure which is an integral part of an electrical accessory and provides protection against external influences (e.g. mechanical impacts, ingress of solid objects or of water), is covered by the relevant standard for such an accessory.

NOTE In UK enclosures complying with this standard cannot be used for the assembly of customer distribution boards (consumer units). Such products must comply with IEC 60439-3 [British standard EN 60439-3].
