S801+R10N3S

The Eaton S801+R10N3S soft starter is a non-combination soft starter with a 105 Amps ampacity rating. It is a device with 3 poles and standard soft starter overload protection. The product line to which the S801+R10N3S soft starter belongs is the Eaton S801 Intelligent Technologies series which offers 12 to 1000 Amps ampacity ratings. This series of soft starters is specifically designed for use with 3-phase motors in a 3-lead (Delta) configuration. The S801+R10N3S soft starter is available in a 110-millimeter R-frame. According to the standard-duty ratings for 60 Hertz line frequency, the starter is compatible with 100-Horsepower motors at 575 Volts AC, 75-Horsepower motors at 460 Volts AC, 40-Horsepower motors at 230 Volts AC, and 30-Horsepower motors at 200 Volts AC. The weight of the S801+R10N3S soft starter is 4.8 kilograms. The starter dimensions are 6.64 x 4.38 x 7.92 inches. The working temperature range for the soft starter is from -40 to 50 degrees Celsius. The starter can be installed at up to 6600 feet without derating. At altitudes higher than 6600 feet, the output of the starter will derate by 0.5% for every additional 330 feet of elevation. The vibration rating for operation is 3 G in any direction. The shock rating is 15 G in any direction. To avoid burns and electric shocks, the power to the S801+R10N3S soft starter, motor, and other devices should be disconnected before any work is started. Any disconnected device should not be connected to the output of the S801+R10N3S soft starter until a means for switching off the soft starter is used when the disconnect switch is open. The failure of the soft starter occurs when the disconnect switch is closed while the S801+R10N3S soft starter is operating.

Eaton Corporation’s S801+R10N3S soft starter is part of the S801+ series. The S801+ are the smallest and most compact soft starter range that is used specifically with 3-phase motors in Delta configuration. This soft-starter comes with built-in Overtemperature detection, forcing the device to shutdown when 100 degrees Celsius is reached. It also comes with stall protection when set speed is not reached after the set ramp time. Additional features for the S801+R10N3S include jam protection, preventing motor damage during normal run, phase loss and phase reversal, and kick start, which increases current of up to 550 % of FLA for a short period - specifically, 0-2 seconds to achieve increased torque. The S801+R10N3S also includes ramp start, which increases motor speed at specified time periods, current limit start, which is used to limit the motor current during start-up, and soft stop for controlled stopping of a frictional load. It also has Shorted SCR detection capability for detection of shorted power poles.

The S801+R10N3S input supply voltage requirement is 200-600 Volts AC, 47-63 Hertz, and 24 Volts DC for control circuit. The starter’s output current is 105 Amperes while the output power varies according to the input and set voltage such as 20 Horsepower @ 200/208 Volts 3PH; 40 Horsepower @ 230/240 Volts 3PH; 75 Horsepower @ 460/480 Volts 3PH, and 200 Horsepower @ 575/600 Volts 3PH.

The S801+R10N3S has an R-Type frame which measures 110 millimeters. The startup class of this starter are CLASS 10 (star-delta replacement); CLASS 20 (heavy starting duty 3 x Ie for 45 s), and CLASS 30 (6 x Ie for 30 s). It has IP20 protection rating and IP00 for terminals. Optional terminal cover with catalog number SS-IP20-N will make the starter full IP20 compliant.
