Okken: the safety Okken switchboards are type tested assemblies (TTA). complying with IEC 60439-1 standard. Only equipment produced according to this switchboard specifications standard guarantee installation safety and reliability. IEC 60439-1 standard defines ten compulsory tests guaranteeing conformity of the electrical switchboard: 7 type tests (manufacturer) 3 routine tests (panelbuilder)
For Okken. all tests were carried out in the most unfavorable conditions. Partitions Okken switchboards. respect protection of persons by the choice of functional unit partitions required by the IEC 60439-1 standard: incomers:
forms 3b. 4b
feeders:
forms 2b. 3b. 4a. 4b
Identification of potentially dangerous areas The red color is used to mark out elements protecting removable live parts. Striker system A mechanical striker forbids the on-load withdrawal of a Compact NS or NSX 100 to 630 installed on a POLYFAST.
Standard OKKEN meets the main national and international standards for TTA equipment (Type Tested Assemblies): IEC 60439-1
