An essential and robust solution for safely starting medium to large-sized Three-Phase AC Induction Motors and Submersible Pumps. This heavy-duty, oil-immersed starter utilizes the Star-Delta method to significantly reduce the high inrush current and starting torque, ensuring a smooth start and extending the life of your motor and machinery.

• Reduced Starting Current: Connects the motor in a 'Star' configuration initially, reducing the starting current to approximately $1/sqrt{3}$ of the direct-on-line current, protecting the motor and power grid.

• Superior Arc Quenching: The contact tips are oil-immersed in high-grade transformer oil, which instantly quenches the arc, preventing pitting and ensuring significantly longer contact life.

• Comprehensive Motor Protection: Equipped with highly reliable protection mechanisms against:

  • Overload

  • Single Phasing

  • Phase Imbalance/Unbalanced Voltage

• Durable Construction: Housed in a robust, Powder Coated Mild Steel Body for excellent corrosion resistance and durability in harsh industrial and agricultural environments.

• Wide HP Range: Suitable for a wide variety of motor ratings, making it highly versatile for different applications.

An essential, reliable, and robust motor starter designed for the smooth and safe operation of medium to large Three-Phase AC Induction Motors and Submersible Pumps. Utilizing the proven Star-Delta starting method, this starter effectively reduces the high initial current surge, protecting your motor and extending its service life.

• Arc Quenching: The contacts are submerged in high-quality transformer oil, providing superior arc quenching during switching and ensuring extended contact tip life.

• Reduced Stress: The Star-Delta connection minimizes the high inrush starting current and mechanical shock to the motor, making it ideal for high-inertia loads.

• Durable and Reliable: Built with high-grade components for reliable performance under varying industrial and agricultural power conditions, typical in India.

• Simple Operation: Features a clear lever mechanism for manual transition from STAR position (Start) to DELTA position (Run). (Caution labels instruct to push the handle to the start position and then hold it for a few seconds before changing over.)

• Wide Application: Perfect for use with submersible pumps, flour mills, compressors, and various three-phase industrial machinery.

The Sakshi SORS (Stator-Rotor Starter) is a specialized, oil-immersed motor starter engineered for controlling and starting Slip-Ring Induction Motors. This system limits the high inrush current and controls the starting torque by adding resistance to the motor's rotor circuit in a series of steps. The oil-immersed design ensures that the contacts and resistors operate in a cool, arc-quenched environment, providing smooth, jerk-free acceleration for heavy-duty loads.

• Motor Type: Specifically designed for Slip-Ring Induction Motors.

• Starting Method: Rotor Resistance Starting (Stator and Rotor control combined).

• Control: Manual or Semi-Automatic (with a dedicated Rotor Controller/Handle).

• Benefit: Provides high starting torque while drawing a low starting current, essential for heavy industrial machinery.

• Arc Quenching: All contacts are submerged in insulating oil for superior arc suppression and extended component life.

• Durability: Floor-mounted, robust construction built to withstand continuous industrial use.

• Application: Ideal for high-inertia loads like Cranes, Ball Mills, Conveyors, Cement Machinery, and large Pumps.

• Motor HP/kW Range: 10 HP up to 300 HP (Varies by model)

• Rated Voltage: 415 V AC

• Phase: 3 Phase

• Rotor Controller: Interlocked with the OCB for sequential starting.

• Type: The label on the side clearly says "SAKSHI D.O.L. STARTER" on one line and another line of text which is partially obscured but looks like 'OIL IMMERSED'.

• Appearance: It has a more traditional oil-starter look with a visible sight-glass or level indicator and a distinct main body. It features a simple green 'START/ON' and red 'STOP/OFF' button.

• Function: Like the SSA, this is a type of DOL starter that uses oil to cool and extinguish the arc when the contacts operate, ensuring safe operation and motor protection. The model may represent a simpler, more robust, or different horsepower range than the SSA.
