With ArTu is possible to build switchboard’s complying with the new IEC 61439-1 and IEC61439-2 Standards If…

correctly selected and assembled, as per the indications given in the distribution catalogue and in the instruction manual

sizing the conductors according to the prescriptions of the IEC 61439-1

carrying out the individual tests foreseen under the IEC 61439-1 Standard successfully

by using the metalwork structures, ABB SACE, air moulded-case and modular circuit-breakers, mean that no further type tests need to be carried out

1. Checking temperature rise limits 2. Checking dielectric properties 3. Checking short-circuit withstand 4. Checking protective circuit

effectiveness 5. Checking clearances and

creepage distances 6. Checking mechanical operation 7. Checking degree of operation 8. Test 8-3-1: Overall inspection 9. Test 8-3-2 or 8-3-4: Insulation

checking 10. Test 8-3-3: Checking protection

measures & electrical continuity of protective circuits

Performed and carried out in ABB & Falcon Lab on Configurations of ArTu (enclosure & Cubicles) with all components configuration (from 100A – 4000A)

The 3 routine tests must be carried out by the installer for each switchboard
