  Управление переменным (AC) и постоянным током  (DC)

  DIN EN 60947-4-1 (VDE 0660, Часть 102)

  Контакторы пригодны для использования в любых климатических условиях. Они имеют защиту от прикосновения обслуживающего персонала согласно DIN VDE 0106 Часть 100.

  Принадлежности к 3-х полюсным контакторам программы SIRIUS 3RT10 могут также применяться и для 4-х полюсных контакторов.

  Область применения

  • Коммутация активных нагрузок
  • Отключение систем с изолированной и плохо заземленной нейтралью
  • Переключение в сети с альтернативным источником переменного тока
  • В качестве контакторов, например, для приводов с регулируемой частотой вращения, когда контактор только пропускает ток, но не коммутирует его

  Auxiliary switches

  The auxiliary switches can be designed as positively driven contacts in 3RH contactor relays or also as mirror contacts in the case of 3RT power contactors.

  For more information on positively driven operation and mirror contacts, see Manuals → "More Information".

  Snap-on auxiliary switch blocks

  A maximum of eight auxiliary contacts can be attached, please note the following:

  • Of these eight auxiliary contacts, there must be no more than four NC contacts.
  • Ensure the symmetry of laterally mounted auxiliary switch blocks

  Surge suppressors without LED

  (also for spring-type terminals)

  All 3RT13 contactors can be retrofitted with RC elements or varistors for damping opening surges in the coil. Diodes or diode assemblies (comprising noise suppression diodes and Zener diodes for short break times) can be used.

  With these contactors, varistors, RC elements and diode assemblies can be plugged on directly at the coil terminals, either on the top or underneath.

  The plug-in direction of the diodes and diode assemblies is determined by a coding device.

  Note:

  The OFF-delay of the NO contact and the ON-delay of the NC contact are increased if the contactor coils are attenuated against voltage peaks (noise suppression diode 6 to 10 times; diode assembly 2 to 6 times, varistor +2 to 5 ms).

  Coupling links for control by PLC

  • Operation with 24 V DC
  • Operating range 17 to 30 V
  • Low power consumption of 0.5 W
  • An LED indicates the switching state.

  The 3RH2924‑1GP11 coupling link has an integrated surge suppressor (varistor) for the contactor coil being switched and is mounted onto the size S0 contactor coil via a coil connection module.

  Sealable covers

  When contactors and contactor relays are used in safety-related applications, it must be ensured that it is impossible to operate the contactors manually.

  For SIRIUS contactors there are sealable covers available for this purpose as accessories; these prevent accidental manual operation. These are transparent molded-plastic caps with a bracket that enables the contactor to be sealed.
