low voltage systems in closed construction– model series ue20

The low voltage systems of the model series UE20 are applicable for power grids, as well as for industrial systems.  Due to the modular construction, they can be distributed as individual fields or as switch system, whereby equipment, field sequence etc can be chosen specifically.

Technical data:

  • Rated insulation voltage Ui: up to 1.000V,
  • Rated operational voltage Ue: up to 690V,
  • Rated impulse voltage Uimp: up to 8kV,
  • Rated frequency: 50Hz,
  • Rated short-time withstand current Icw: z.Zt. up to 65kA (1s),
  • Rated current Ipk: z.Zt. up to 143kA,
  • Nominal current: up to 4.000A,
  • Protection class: IP20,
  • Setup: in electrical operating rooms,
  • Sheet metal parts powder-coated (Standard RAL 7032, variant colour tones at customer’s option possible).

Switch devices

The infeed is carried out alternatively from top or bottom over circuit breakers (in fixed-installation technology or withdrawable-unit design), NH fuse switch disconnector or switch disconnector. Field couplings are carried out over circuit breakers, switch disconnectors or NH coupling bars. The NH fuse load switches and the moulded case circuit breakers (up to 1600 A) are used as tap-off devices and switch devices.

Options:

  • Current measurement and voltage measurement of the infeed by means of flowmeter/voltage meter or multi measuring device,
  • Current measurement of the tailings,
  • Transfer measurement over sealable transforming fishing plates and voltage path switches (total or e.g. infeed(s) + supply),
  • Ward supply, service power socket or similar,
  • Switching devices with motor drive,
  • Uncoupling protection, QU protection according to the German Association for energy and water economy,
  • Automatic restart (for ex. after activation by means of uncoupling protection),
  • Automatic transfer (for ex. infeed 1, infeed 2, coupling)
  • Special solutions:

- Special measures (for ex. in case of constricted rooms),

- Tailings to the top,

- Switch devices 4 poles,

- Angle plate, base or similar,
