WSTRM Series
Winston
5.5kw - 55kw intelligent 3 Phase Motor Soft Starter with bypass contactor 220V
The WSTRM softstarter is the most compact of all the softstarter ranges which allows for design of compact starting equipment. A WSTRM built-in bypass contactor, the energy losses inside the softstarter are highly reduced.
| Secure motor | Reduce the electrical stresses and keep the motor protected with the MMS |
| Reliability | The WSTRM reduces the starting current for the motor. The possibility to connect it to the manual motor starter makes it possible to build a compact and complete starting solution with overload and short-circuit protection |
| Improve installation | Saving time and money with built-in bypass and easy setup |
| Efficiency | On the WSTRM, the bypass is built in, saving you time during installation and space in your panel. Set-up is done through three potentiometers making it very fast and easy. |
| Increase application | Reduce the mechanical stresses on your motor |
| Productivity | Soft start and stop with PSR will reduce mechanical wear and tear on the application and increase the availability and uptime. |
Product conditions
Input voltage | AC380V(-15%~+15%),50Hz |
Applicable motor | Squirrel-cage asynchronous motor (please specify when ordering winding motor); |
Starting frequency | Standard products are recommended to start and stop no more than 6 times per hour; |
Cooling mode | Natural air cooling; |
Installation | Wall-mounted; |
Protection level | IP20 |
Environmental conditions | Altitude,<2000 m, or>2000 m, corresponding reduced capacity use; The environment temperature at 25 ℃ ~ + 40 ℃. Relative humidity is not more than 95% (20 ℃ + / - 5 ℃) without any condensation; No flammable, explosive, corrosive gas, no conductive dust. Indoor installation, good ventilation.Vibration less than 0.5G. |
