A.1 Standards and approvals
Standards
The switch disconnectors of the 3KF series comply with the following international standards:
IEC 60947-3
EN 60947-3 Load break switches, disconnectors, switch disconnectors and fuse-combination units
EN 60947-1
EN 60947-1 Low-voltage switchgear and controlgear – Part 1: General rules
GB 14048-3 (CCC) Switches, load break switches, disconnectors
EN 60947-1 Annex Q Special tests – humidity, heat, salt spray, vibration and shock, category = E
IEC 60947-5-1
GB 14048-5-1
EN 60947-5
Auxiliary switch
DIN 43880 Built-in equipment for electrical installations; overall dimensions and related mounting dimen-
sions
EN 60715 Dimensions of low-voltage switchgear and controlgear
Standardized mounting on rails for mechanical support of electrical devices in switchgear and
controlgear installations
DIN 46234 Cable lugs for solderless connections; ring type, without insulating sleeve, for copper conductors
DIN 46235 Cable lugs for compression connections; cover plate type for copper conductors
DIN 46206-2 Connections for electrical equipment; flat terminals >= 40 A, basic dimensions and assignment
UL 508 Standard for Industrial Control Equipment
UL508 for 3KF SITOR
The 3KF switch disconnector with SITOR fuses is certified according to UL508.
Because fuses for semiconductor protection according to UL fall under category Special
Purpose Fuses, the 3KF SITOR combined with SITOR fuses (if UL certified) can also be
used in the UL area, even though the fuses with LV HRC have a typical IEC design.
Users can, of course, install the switch disconnector in installations that are exported to the
USA.
