Technical Specification
| Parameters | Description |
|---|---|
| Configuration | Three phase close delta (In Line) or open delta (Inside Delta) |
| Control Action | Phase angle control (self - synchronized) |
| Control Switches | Front panel push button switches for Start/Stop to start and stop the motor. Reset push button switch to use in case of overload trip condition. (Optionally – the control switch connections can be given on the terminals for external remote operation). |
| Incomer Supply | 415VAC/440VAC @ 50Hz. (690VAC – optional) |
