Description

Industry Description

Load feeder fuseless direct start, AC 400V, sz s00 1.8. . .2.5a, DC 24v screw connection for rail-mounting, type of coordination 2, iq = 150ka (also fulfills type of coordination 1) 1NO (contactor)

AD Description

SIRIUS 3RA21101CA151BB4 Fuseless Load Feeder Starter, 24 VDC V Coil, Reversing Action, 3 Poles, IP20 Enclosure

Vendor Description

The 3RA2 fuseless load feeders consist of the 3RV2 motor starter protector and the 3RT2 electromechanical contactor. The devices are electrically and mechanically connected using pre-assembled assembly kits (link modules, wiring kits and standard mounting rail or busbar adapters). Around 500 pre-assembled 3RA2 combinations of these innovative 3RT2 controls and 3RV2 protection equipment can be ordered for direct on line and reversing starting of standard three phase motors up to 32 A (approximately 15 kW/400 VAC). In the 3RA2 load feeder, the 3RV2 motor starter protector is responsible for overload and short circuit protection. Back up protective devices, such as melting fuses or limiters, are superfluous here, as the motor starter protector is short circuit proof up to 150 kA at 400 VAC.

Special Features

  • Connection of feeders to the control system through standardized system connection, for fast integration in TIA and less wiring work
  • High operational reliability through short circuit breaking capacity of 150 kA with type of coordination 1 and 2
  • High planning reliability through consistent combination tests for fuseless and fused configuration
  • Minimum planning and assembly work and far less wiring with the preassembled complete units
  • Plug-in connectors from the motor starter protector to all types of SIRIUS controls, for quicker and error free assembly of feeders with screw and spring type connection
  • Power loss 5 to 10% smaller than for comparable devices, hence lower energy consumption
  • Spring type connection possible throughout enhanced operational reliability and less wiring work thanks to plug-in connections
