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.

No	Characteristic to be Checked	Clause	Responsibility	Comments
1	Strength of material and parts:	10.2
	Resistance to corrosion	10.2.2	Original Manufacturer	The Bowen Series of enclosures are made from Stainless Steel and as such do not have any corrosion effects as measured by the Standard thereby exceeding the comparative testing done. Plus, ES report; 103687.
	Thermal stability (relates to non-metal enclosures)	10.2.3.1	Original Manufacturer	This clause refers mainly to plastic enclosures.
	Resistance to abnormal heat and fire (due to internal electric effect)	10.2.3.2	Original Manufacturer	All insulating materials supplied have been tested to 960ÂºC glow-wire Standard. Plus, ES report; 103863
	Resistance to ultra-violet (UV) radiation	10.2.4	Original Manufacturer	UV ratings refer mainly to plastic enclosures. Bowen enclosures are stainless steel and have zero UV degradation.
	Lifting	10.2.5	Original Manufacturer	Lifting is verified by test, if required. Bowen enclosures are provided with lifting lugs rated to one tonne.
	Mechanical Impact	10.2.6	Original Manufacturer	IK10; Metal enclosure systems have been tested to exceed IK10 (20 Joules).
	Marking	10.2.7	Assembly Manufacturer	Markings must be verified by test. Tests are performed by rubbing with water and petroleum spirits; generally done by the Switchboard Builder (Assembler).
2	Degree of protection of enclosures (IP)	10.3	Original Manufacturer	IP66; Ingress Protection (IP) rating needs to be verified by test or by assessment. SIMTARS report; NE99/0034
3	Clearances	10.4	Assembly Manufacturer	Clearance 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.
4	Creepage distances	10.4	Assembly Manufacturer
5	Protection against electric shock and integrity of protective circuits	10.5
	Effective continuity between the exposed conductive parts of the ASSEMBLY and the protective circuit	10.5.2	Assembly Manufacturer	Equipotential protective earth bonding points are required to be verified by test to less than 0.1ohm. Similar enclosure designs have been tested by PlusÂ ESÂ report;Â 103687.
	Short-circuit withstand strength of the protective circuit	10.5.3	Original Manufacturer	The Bowen Series are generally understood to be fitted with equipment making the switchboard not exceed 10kA prospective short-circuit withstand rating (Icp).
6	Incorporation of switching devices and components	10.6	Assembly Manufacturer	Points 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.
7	Internal electrical circuits and connections	10.7	Assembly Manufacturer
8	Terminals for external conductors	10.8	Assembly Manufacturer
9	Dielectric Properties	10.9
	Power-frequency withstand voltage	10.9.2	Original Manufacturer	The Bowen 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.
	Impulse withstand voltage	10.9.3	Original Manufacturer
10	Temperature-rise limits	10.1	Assembly Manufacturer	Temperature-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 Bowen Series of enclosures are rated not to exceed 1600A and therefore AS/NZS 60890 should be used by the Designer.
11	Short circuit withstand strength	10.11	Original Manufacturer	The Bowen Series are generally understood to be fitted with equipment making the switchboard not exceed 10kA prospective short-circuit withstand rating (Icp).
12	Electromagnetic compatibility (EMC)	10.12	Original Equipment Manufacturer	Equipment 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.
13	Mechanical operation	10.13	Original Equipment Manufacturer	This 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.

Case Studies

Simandou Mine

The development of the Simandou mine required custom power distribution boards and control systems capable of withstanding the harsh mining environment.
