This video shows how to assemble the Star-Delta Kit with the three contactors.
The selection used would be suitable for a 22kW motor at 400Vac, we would recommend an LRD22 overload for this combination.
The Kit LAD93217 can be used in the following combinations:
| kW at 415V AC | Motor FLC (A) | Line Contactor | Delta Contactor | Star Contactor | Star-Delta Kit | Overload Current (FLC x 0.58) | Recommended Overload |
|---|---|---|---|---|---|---|---|
| 22 | 40 | LC1D25** | LC1D25** | LC1D09** | LAD93217 | 23 | LRD22 |
| 30 | 55 | LC1D32** | LC1D32** | LC1D18** | LAD93217 | 32 | LRD35 |
** = Coil Voltage code e.g F7 - 110V AC
List of parts used in this Video:
- LC1D25F7 Line Contactor - 110Vac coil
- LC1D25F7 Delta Contactor - 110Vac coil
- LC1D09F7 Star Contactor - 110Vac coil
- LAD93217 Star-Delta Kit (Including Timer)
The pre-assembled LC3D***** star-delta contactors of this size are no longer a standard stocked item in the UK, however the combinations can be assembled for 7.5 - 132kW motors using Star-Delta Kits (LAD*), contactors and overloads.
