Reduced Voltage Starters

IT Family Soft Starters

The IT. Intelligent Technologies line of Reduced Voltage Soft Starters are compact, multi-functional, easy to install, and easy to program. Designed to control acceleration and deceleration of 3-phase motors, the line is available for current ranges from 0.8 amp through 1,000 amp applications and is suitable for mounting in motor control centers or in enclosed control (IP21, IP54 & IP65) applications. The IT. Intelligent Technologies Soft Starters offer integral run bypass, motor overload protection and advanced diagnostics.

S752 Soft Starters

The Intelligent Technologies (IT.) S752 Line of Reduced Voltage Soft Starters is very compact, multi-functional, easy to install, and easy to program. The S752 is a cost effective alternative to the smaller frame S801 line while still offering the many of the same features. Designed to control acceleration and deceleration of 3-phase motors, the line is available for current ranges from 0.8 amp through 50 amp applications and is suitable for mounting in motor control centers or in enclosed control (IP21, IP54 &IP65) applications. The S752 Soft Starters offer integral run bypass, motor overload protection and diagnostics.

S801/S811 Soft Starters

The S801/S811 line of Intelligent Technologies Soft Starters is designed to be the smallest, most compact soft starter in the market today. With this small size, it can easily fit in place of existing soft starter designs, wye-delta starters or across-the-line NEMA and IEC starters. This feature allows easy retrofits of existing Motor Control Centers or Enclosures and saves the expense of replacing existing structures or adding a new one to house a soft starter. The product is designed to work with 3-phase motors in a Delta (3-lead) configuration. The S801/S811 works with all motors from fractional horsepower up to motors requiring 1000 amps of steady state current. The built-in over-load (in ranges from 12 - 1000 amps) and run bypass contactor make installation and setup quick and easy. The overload also offers some advanced protective functions to give additional motor protection.

With the pump control option, it is the number one soft starter available for pumping applications. The unique soft stopping control provides a smooth transition for stopping a motor and eliminating the "water-hammer" effect that can damage pipes, valves, and pumps.

SMV801 Medium Voltage Soft Starters

The Cutler-Hammer Intelligent Technologies IT. MV801 line of reduced voltage soft starters from Eaton are very compact, multi-functional, easy to install and easy to program. Designed to control the acceleration and deceleration of three-phase medium voltage motors up to 5kV. The line is available from 11A through 420A applications as an open unit or in the Ampgard® IT. starter assembly.

The Cutler-Hammer® Intelligent Technologies (IT.) MV801 Line of Reduced Voltage Soft Starters from Eaton’s electrical business is very compact, multi-functional, easy to install and easy to program. Designed to control the acceleration and deceleration of three-phase medium voltage motors up to 5 kV. The line is available from 11 amp through 420 amp applications as an open unit or in the Ampgard® IT. starter assembly. This product is perfect for the OEM who wants to add value by installing the MV801 into their own structure design. The MV801 can easily fit in the space where an existing Reduced Voltage Auto Transformer had been.

The IT. MV801 Line of Reduced Voltage Soft Starters comes standard with the following:

• Control Module
• Control Interface Module

The MV801 has a unique inclusive design encasing the SCRs, power circuitry, run bypass contactors and overload protection, minimizing required mounting space and installation time. The separate control module provides mounting flexibility.

Reduced Voltage Controller

The S701 device is a Reduced Voltage Soft Start Controller designed to control acceleration and deceleration of 3-phase motors. The S701 provides the user with the ability to adjust initial torque, ramp up and down time and also select Kick Start for high inertial loads.

The S701 line of soft start controllers is specifically designed to be a low cost option for soft starting small (15 hp and down) 3-phase motors. The S701 unit controls current on two of three motor phases to control the torque being applied to the motor, allowing for smooth starting of a motor. The S701 is designed to be used with a Manual Motor Starter or a full voltage starter. These devices provide the necessary overload protection for the motor and also provide line isolation for the motor. Short-circuit protection can be provided by fuses or circuit breakers.

Models are available with an auxiliary contact for controlling a bypass contactor and a brake to control deceleration.

Features

• Rated operational voltage up to 600V AC
• Control voltage range from 24 to 300V AC/DC
• Adjustable ramp times (.5 – 10 seconds)
• Adjustable initial torque control (0 – 85%)
• Kick Start feature n Soft Stop (.5 – 10 seconds)
• Unlimited number of START/STOP operations per hour
• IP20 finger protection
• Fractional to 15 hp motors @ 480V (20 hp @ 600V)

Benefits

• Reduced wear on belts, gears, chains, clutches, shafts and bearings
• Allows for controlling the inrush current to the motor
• Reduced water-hammer in pumping applications
• Less shock to product on conveyor lines and material handling gear
