Identical accessories for 3KA switch disconnectors and for 3KL and 3KM switch disconnectors with fuses simplify stock keeping. Please inquire about a special variant with reduced values that is particularly resistant to atmospheres high in sulfur, e. g. in the paper and cellulose processing industries.
3KL switch disconnectors with fuses protect against overload and short-circuits as main and EMERGENCY-STOP switches of switch boards, distribution boards, power supply and motor outgoing feeders. In conjunction with Siemens SITOR semiconductor fuses, they are also used in UPS systems, frequency converters and capacitor control systems. All 3K switch disconnectors are climate-proof and meet the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660 Part 107.

Permissible load current in the switch disconnector. In the case of cyclic loads, the currents may have to be reduced again (precise values on request).
Due to the mechanical stress on the relatively long fuse blades, SITOR 3NE41 fuses should be switchable only occasionally and only at zero current. Values in black in brackets apply to 3KL62 switch disconnectors. Values in blue in brackets apply to 3KM switch disconnectors.
For technical specifications and dimensional drawings of the SITOR fuses see Catalog ET B1.
SENTRON 3KM Switch Disconnectors with Fuses and Isolating Plug Connector up to 400 A
All switch disconnectors feature double contact interruption and an isolating distance. As a result, the fuses are de-energized when the switch disconnectors are in the disconnected position. The 3KM switch disconnectors with fuses also feature an isolating plug connector. This facilitates mounting and contact establishment in motor control centers (MCCs) in conjunction with vertical busbars. Generally, all 3K. 5 switch disconnectors can be
secured on the shaft with a padlock to prevent unauthorized reclosing. Identical accessories for 3KA switch disconnectors and for 3KL and 3KM switch disconnectors with fuses simplify stock keeping. Please inquire about a special variant with reduced values that is particularly resistant to atmospheres high in sulfur, e. g. in the paper and cellulose processing industries.
3KM switch disconnectors with fuses protect against overload and short-circuits as main and EMERGENCY-STOP switches of switch boards, distribution boards, power supply and motor outgoing feeders. In conjunction with Siemens SITOR semiconductor fuses, they are also used in UPS systems, frequency converters and capacitor control systems. All 3K switch disconnectors are climate-proof and meet the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660 Part 107.
