AS/NZS 61439 Compliance

AS/NZS 61439 is the new series of standards for low-voltage (LV) switchgear and control gear assemblies. For more information on whether you need to comply see our AS/NZS 61439 page.

Click the bar below the requirements and responsibilities for complaince with AS/NZS 61439 for this enclosure.

The following definitions apply to this table: -

  • Original Manufacturer* - Switchboard designer and manufacturer of the switchboard enclosure.
  • Assembly Manufacturer* - A switchboard builder.
  • Original Equipment Manufacturer - The company who manufactured the switchgear used in final assembly.

*The original manufacturer and assembly manufacturer can be the same company or different companies.

If you are a SWITCHBOARD BUILDER this means you are the ASSEMBLY MANUFACTURER and you may be the ORIGINAL MANUFACTURER too. Any switchgear you order will need to be covered by the requirements of the Original Equipment Manufacturer.

B&R has some (but not all) of the responsibilities of the ORIGINAL MANUFACTURER.

If you are an END USER of the equipment you can see who has responsibility from these definitions.

NoCharacteristic to be CheckedClauseResponsibilityComments
1Strength of material and parts:10.2
Resistance to corrosion  10.2.2Original ManufacturerThe Universal NI Series of enclosures are made from steel and stainless steel and as such exceed standards requirements. Comparative testing done, Plus ES report; 103687.
Thermal stability (relates to non-metal enclosures) ManufacturerThis clause refers mainly to plastic enclosures.
Resistance to abnormal heat and fire (due to internal electric effect) ManufacturerAll insulating materials supplied have been tested to 960ºC glow-wire Standard. Plus ES report; 103863
Resistance to ultra-violet (UV) radiation  10.2.4Original ManufacturerUV ratings refer mainly to plastic enclosures however metal Powder-coat painted enclosures incorporates UV stabilization. AksoNobel report; 20LSR178
Lifting  10.2.5Original ManufacturerLifting is verified by test, if required. Generally this relates to larger switchboards to which lifting means (lugs) have been provided.
Mechanical Impact  10.2.6Original ManufacturerIK10; Metal enclosure systems have been tested to exceed IK10 (20 Joules).
Marking  10.2.7Assembly ManufacturerMarkings must be verified by test. Tests are performed by rubbing with water and petroleum spirits; generally done by the Switchboard Builder (Assembler).
2Degree of protection of enclosures (IP)10.3Original ManufacturerIP55; Ingress Protection (IP) rating needs to be verified by test or by assessment. SIMTARS report; NE05/0077
3Clearances10.4Assembly ManufacturerClearance and creepage can only be verified by test. Switchboard Builders (Assembler) must maintain compliance by ensuring correct clearance and creepage distances are maintained at >8mm (Uimp=8kV) and >16mm (Ui=1kV) respectively.
4Creepage distances10.4Assembly Manufacturer
5Protection against electric shock and integrity of protective circuits10.5
Effective continuity between the exposed conductive parts of the ASSEMBLY and the protective circuit   10.5.2Assembly ManufacturerEquipotential protective earth bonding points are required to be verified by test to less than 0.1ohm.
Short-circuit withstand strength of the protective circuit   10.5.3Original ManufacturerThe Universal NI Series are generally understood to be fitted with equipment making the switchboard not exceed 10kA prospective short-circuit withstand rating (Icp).
6Incorporation of switching devices and components10.6Assembly ManufacturerPoints 6, 7 and 8 are largely the responsibility of the Switchboard builder (Assembler). It is a requirement that the Assembler follow guidance from the original manufacturer. The advice of original manufacturers such as B&R and switchgear manufacturers, needs to be adhered to. Switchboard Builders need to be aware of the StandardÂ’s requirements for these verification points and incorporate these into complete design verification documentation.
7Internal electrical circuits and connections10.7Assembly Manufacturer
8Terminals for external conductors10.8Assembly Manufacturer
9Dielectric Properties10.9
Power-frequency withstand voltage  10.9.2Original ManufacturerThe Universal NI Series of enclosures are provided as a basic empty enclosure and as such dielectric property verification has not been possible as internal configurations are not known. Dielectric properties need to be verified by Impulse withstand testing or by assessment, reference clearances and creepages.
Impulse withstand voltage  10.9.3Original Manufacturer
10Temperature-rise limits10.1Assembly ManufacturerTemperature-rise can be determined by test or by comparison or by calculation. Temperature rise methods provided in AS/NZS 60890 can be used for switchboards not exceeding 1600A rating. The Universal NI Series of enclosures are rated to not exceed 630A and therefore AS/NZS 60890 should be used by the Designer.
11Short circuit withstand strength10.11Original ManufacturerThe Universal NI Series are generally understood to be fitted with equipment making the switchboard not exceed 10kA prospective short-circuit withstand rating (Icp).
12Electromagnetic compatibility (EMC)10.12Original Equipment ManufacturerEquipment installed in switchboards shall comply with the immunity requirements of the relevant product or generic EMC standard. The Switchboard builder (assembler) shall obtain from the device and or component manufacturer the specific performance criteria of the equipment based on the acceptance criteria given in the relevant standard.
13Mechanical operation10.13Original Equipment ManufacturerThis verification testing need NOT be done on devices already been type tested according to their relevant product standard. Only if their mechanical operation has been modified does the assembly need to be retested by cycling it 200 times.
