|Strength of material and parts:
|Resistance to corrosion
|Testing has shown zinc-coated steel resists corrosion to 1000 hours of neutral salt spray, exceeding the 61Compliance.
|Thermal stability (relates to non-metal enclosures)
|Metal enclosures have no thermal stability requirements.
|Resistance to abnormal heat and fire (due to internal electric effect)
|Insulation materials have been verified by external NATA laboratory.
|Resistance to ultra-violet (UV) radiation
|Metal enclosures do not require UV verification except when painted. B&R use industrial grade powder-coat paint which incorporates UV stabilisation and is certified by our supplier.
|Lifting requirements have been verified by external NATA laboratory.
|Internal testing verifies that enclosures exceeds IK10 required.
|Labels supplied by B&R are manufactured from plastic laminated materials and meet all 61Compliance requirements. Switchboard builders need also to take note of 61Compliance requirements for a labelling. Markings have been verified by external NATA laboratory.
|Degree of protection of enclosures (IP)
|All IP requirements have been verified by external NATA laboratory.
|Clearances have been verified by external NATA laboratory.
However, the SBB must also ensure compliance by ensuring correct clearances are maintained as per the Standard and original equipment manufacturers installation instructions.
|Protection against electric shock and integrity of protective circuits
| Effective continuity between the exposed conductive parts of the ASSEMBLY and the protective circuit
|Protective circuits have been verified by external NATA laboratory.
However, the SBB must also ensure effective continuity between exposed conductive parts of an assembly and protective circuits are maintained (less than 0.1ohm).
| Short-circuit withstand strength of the protective circuit
|Protective circuits short-circuit withstand strength has been verified by external NATA laboratory.
However, the SBB must also ensure compliance by ensuring correct implementation of protective circuits as per the Standard and original equipment manufacturers installation instructions.
|Incorporation of switching devices and components
|This is the responsibility of the SBB; however, it is a requirement that the SBB follows guidance from the original equipment manufacturer (OEM). The advice and guidance of the OEM such as B&R and switchgear manufacturers needs to be adhered to while maintaining compliance to Standards and State based Regulations and Service and Installation Rules (SIR).
|Internal electrical circuits and connections
|Terminals for external conductors
|Power-frequency withstand voltage
|Withstand voltages have been verified by external NATA laboratory.
However, the SBB must also ensure effective assembly of the switchboard, adhering to all OEM installation Instructions.
|Impulse withstand voltage
|FUNCTIONAL UNITS: Test verified and certified by an external NATA laboratory to AS/NZS 3439.1 which complies with AS/NZS 61439.1. Limits as per Table 2 carried out on switchboards including busbars, incoming and outgoing units.
BUSBAR: Test verified and certified by an external NATA laboratory to AS/NZS 3439.1. Test results comply with the requirements of AS/NZS 61439.1.
Contact B&R for more information on temperature rise requirements.
|Short circuit withstand strength
|FUNCTIONAL UNITS - Test verified and certified by an external NATA laboratory to AS/NZS 3439.1 and AS/NZS 61439.
BUSBAR - Test verified and certified by an external NATA laboratory to AS/NZS 3439.1 and AS/NZS 61439.
Contact B&R for more information on short-circuit withstand requirements.
|Electromagnetic compatibility (EMC)
|Original Equipment Manufacturer
|Equipment installed in switchboards must comply with the immunity requirements of the relevant product or generic EMC standard. The SBB must obtain from the OEM the specific performance criteria of the equipment based on the acceptance criteria given in the relevant standard.
|Original Equipment Manufacturer
|Mechanical operation relates to situations where switchgear operation has been changed beyond their original approval. However, SBB must ensure compliance if modifications have been made.
