The 3RE1 encapsulated starters are available as direct-on-line starters and as reversing starters.

These starter combinations are located in a molded-plastic enclosure that provides effective protection against dust and splashwater thanks to its high degree of protection IP65. This high degree of protection is also met by the actuating elements used for switching on and off manually on-site.

Either external fuses (fused design) or motor starter protectors/circuit breakers (fuseless design) must be used for short-circuit protection.

Direct-on-line starters

The direct-on-line starters are available in three sizes:

• Size S00 is suitable for three-phase motors up to 5.5 kW with 400 V AC and a maximum rated motor current of 12 A. The starters are available in the following two versions:
  
  • Molded-plastic enclosure for direct-on-line starters including contactor – in this case the overload relay must be selected and ordered according to the rated motor current.
  • Molded-plastic enclosure for direct-on-line starters (without contactor) – in this case the contactor and overload relay must be selected and ordered separately.
• Size S0 is suitable for three-phase motors up to 11 kW with 400 V AC and a maximum rated motor current of 25 A. The starters are available in the following two versions:
  
  • Molded-plastic enclosure for direct-on-line starters including contactor – in this case the overload relay must be selected and ordered according to the rated motor current.
  • Molded-plastic enclosure for direct-on-line starters (without contactor) – in this case the contactor, auxiliary switch and overload relay must be selected and ordered separately.
• Size S2 is suitable for three-phase motors up to 22 kW with 400 V AC and a maximum rated motor current of 50 A. The starters are available in the following version:
  
  • Molded-plastic enclosure for direct-on-line starters (without contactor) – in this case the contactor, auxiliary switch and overload relay must be selected and ordered separately.

Reversing starters

The reversing starters are available in two sizes:

• Size S00 is suitable for three-phase motors up to 5.5 kW with 400 V AC and a maximum rated motor current of 12 A. The starters are available in the following two versions:
  
  • Molded-plastic enclosure for reversing starters including contactor assembly – in this case the overload relay must be selected and ordered according to the rated motor current.
  • Molded-plastic enclosure for reversing starters (without contactor assembly) – in this case the contactor assembly, auxiliary switch and overload relay must be selected and ordered separately.
• Size S0 is suitable for three-phase motors up to 11 kW with 400 V AC and a maximum rated motor current of 25 A. The starters are available in the following version:
  
  • Molded-plastic enclosure for direct-on-line starters (without contactor assembly) – in this case the contactor assembly, auxiliary switch and overload relay must be selected and ordered separately.
