AutomationDirect's Stellar SR33 Series basic soft starters are designed for general-purpose applications

AutomationDirect's Stellar SR33 Series basic soft starters are designed for general-purpose applications where traditional across-the-line starting or wye-delta starting would typically be appropriate. The SR33 semi-conductor soft starters, available in 22A to 482A sizes, are suitable to control three-phase AC induction motors with a variety of motor loads. All units feature two-phase control, separately adjustable motor start voltage and start and stop times, and, depending on model, fault indication of 4 or 7 fault types: SCR or Power Supply, Overheat, Control Power Supply, Bypass Relay Failure, Shear Pin, Overload and Overcurrent. The SR33 series soft starters use thyristors for controlled reduced voltage motor starting and stopping, and then switch to internal contacts for efficient running at rated speed.
