The optional DXE-EXT-SET module can be used to easily change parameters with a screwdriver.
Modbus RTU on board
UL Combined Rating: 100kA
IP20 enclosure meets international standards (CE, UL, cUL, cTick, UkrSEPRO, RohHS)

Soft starter S811+

Art. S811+

Three-phase motors are currently the optimal drive for the simple and cost-effective implementation of machine and system concepts. However, direct starting or star-delta starting is not always the best solution. Soft starters offer a gentle alternative for almost any application, ensuring smooth, vibration-free motor starting with line protection.

S811+ soft start up to 850 A.

The soft starter family is ideal for applications such as pumps, fans, and conveyors. Extended maintenance intervals and reduced cost of ownership are additional benefits. The Eaton S811+ soft starter family delivers reliable performance that exceeds the standard protection features found in most soft starters. Choosing a soft starter will increase your productivity and reduce your costs.

Functions:

Compact size, most sizes are the smallest on the market, so more drives can be used in each cabinet
Eliminates abrupt starts and stops, extends the mechanical life of the system, and reduces belt and gearbox maintenance costs
Better engine torque control, increased gearbox and bearing life, reduced belt wear, and elimination of hydraulic shock with a special Eaton pump algorithm
Reduced starting current, reduced peak demand costs
Ready for data exchange - built-in Modbus RTU, no additional functions required
Sophisticated monitoring features: power, power factor, phase currents, phase voltage, device temperature, and more, saving on additional measuring equipment and wiring costs
Overload protection for the motor and soft starter, preventing damage to the device, regardless of normal operation or misuse
Copy-paste keyboard, removable user interface, simplifies commissioning and saves time in series production

Applications:

Three-phase inductive loads
Soft start of the engine in transport and conveyor systems
Smooth pump start reduces load and wear on the entire system (water hammer)
Solid state switching of pumps in extreme conditions of chemical plants and gas stations.
Star-delta replacement (especially for motors over 5.5 kW requiring a current-reducing starting method)
Pumps and fans in heating, ventilation and air conditioning systems
Water supply/wastewater treatment
Fast and noise-reducing control in construction

Soft starter DS7

Art. DS7

The DS7 is Eaton's solution for uninterruptible motor starting with grid protection. Featuring a three-phase motor, the optimal drive for simple and cost-effective machine and system design, the DS7 is the ideal solution.

DS7 - now up to 200 A.

The DS7 is ideal for pumps, fans, and small conveyors. It is a fully integrated component of the xStart system. The DS7 replaces the mechanical contactor and enhances the motor's soft start function. Additional benefits include extended maintenance intervals and reduced operating costs.

Functions:

Integration into the xStart system
The capabilities and extensions of the xStart system can be used without restrictions.
Additional built-in fan to increase switching frequency
Version for extreme environmental conditions down to -40°C

Applications:

Three-phase resistive and inductive loads
Soft start of the engine in transport and conveyor systems
Smooth pump start reduces load and wear on the entire system (water hammer)
Solid-state switching of pumps in extreme conditions of chemical plants and gas stations
Fast and silent control in buildings
Soft start, reducing wear on V-belts in fan drives

STC starting torque controllers

Art. STC

STC starting torque controllers are a cost-effective solution for soft starting low-power single- and three-phase squirrel-cage induction motors. These starting torque controllers help reduce the mechanical and electrical stress on the motor circuits and systems by limiting the starting voltage. This avoids overtorque and overcurrent conditions that occur when short-circuiting circuits across the line, such as when the motor's main control contactor closes.

Offers reliable, proven technology with solid-state power poles
Provides easy commissioning with just two settings:

Initial torque setting (10...80%)
Acceleration time (0.5…5 sec)

Ideal for adding to existing direct start units
Offers energy savings
Less wear on mechanical systems
Offers ideal applications such as:

Basic material processing
Fans
Pumps
Single-phase low-voltage starting devices
