RDJR6 Built-in motor soft starter

This built-in bypass soft starter features advanced control and protectionfunctions, as well as closed-loop control for stabilizing the soft-starttorque. It offers a user-friendly, efficient and reliable solution for motorstarting and operation. It is equipped with three internal relays and doesnot require external contactors. Its compact design is ideal for motorcontrol centers with limited space, simplifying the installation process.

Operating temperature:-10~40℃æ(when the ambient temperature is
40℃æ~50℃æ,please derating the rating),no direct sunlight.
Storage temperature:-20~60℃.
Surroundings Humidity within 90%(no condensation),vibration less than 0.6G;No corrosive,flammable,explosive,
water-absorbent dust,and no accumulation of various lint.
Altitude 0~1000m.The rating shall be derated by 10%forevery 1000m increase.
Control Object Motor Standard wiring refers to the motor windings being connected in delta or star,with the thyristor
connected between the power supply and the motor..Inner delta connection refers to the motor
windings being in a triangle—the thyristors are connected in series with the windings.The main
advantage of the inner triangle control is that the soft starter can be selected at a reduced rating.
The current flowing through the soft starter and the motorin the inner triangle connection is 1/1.
732 of the line current.The above table uses the margin to select the soft starter,which is selected
according to the line current/1.5le.During the selection process,the user can further reduce the
rating of the soft starter according to the actual situation.
