Description
EATON Soft Starter, Non-Combination Standard Duty, Series: S811, 480 VAC, 500 A, 47/63 Hz Frequency, 300 kW Wattage, 400 hp Motor, 21.6/26.4 VAC Coil, 3 Pole, 0.5 to 180 s Timing, 3 ph ph, Lug Connection, Solid-State Overload Relay, 156 to 500 A Full Load, NEMA 0/1/3R/4/4X/7/9/12 Enclosure, Starting Modes: Current Limit/Ramp, -30 to 50 deg C Operating, 19 in L x 14-1/2 in W x 12-1/2 in H Dimensions
Features:
- Communication capabilities with various protocols
- Digital interface module (DIM) provides an intuitive, easy to use human interface with powerful configuration capabilities to maximize system performance
- Door or device mounted dim enables users to safely configure, commission, monitor and troubleshoot the system at the electrical panel without opening the enclosure door
- System operating parameters can be monitored enterprise wide through a communications network
- Increase uptime by providing data for process management and preventive diagnostics
- Run bypass mode greatly reduces internal heating created by the greater power dissipation in the SCRs
- Bypass contactors directly connect the motor to the line and improves system efficiency by reducing internal power losses
- Internal solid state overload protection provides accurate current measurement and trip settings
- Internal run bypass contactors and overload protection eliminate the need for additional devices, reducing enclosure sizes minimizing installation and wiring time and reducing overall assembly size and cost
- Wide range of overload FLA settings and a selectable trip class offers users the flexibility to fine tune the starter to match specific application requirements
- Variable ramp times and torque control settings provide unlimited starting configurations, allowing for maximum application flexibility
- Kick start feature enables soft starting of high friction loads
- Soft stop control for applications where an abrupt stop of the load is not acceptable
- Pump control option with sophisticated pump algorithms on both starting and stopping that minimize the pressure surges that cause water hammer
- 6 SCRs control all 3 motor phases, providing smooth acceleration and deceleration performance
- Soft acceleration and deceleration reduces wear on belts, gears, chains, clutches, shafts and bearings
- Reduce the peak inrush current's stress on the power system
- Minimize peak starting torque to diminish mechanical system wear and damage
Applications:
For controlling the acceleration and deceleration of 3-ph motors, electrical assemblies, panels and OEMs
Standards/Approval:
- CSA C.22.2
- UL 810
- EN 60947-4-2
- CE Certified
