Basic AC Motor Soft Starters

The SSW07, with DSP (Digital Signal Processor) control, was designed to provide great performance on motor starts and stops with an excellent cost-benefit ratio.

• Easy to set up, the SSW07 simplifies start-up activites and daily operations.
• The SSW07 is compact, optimizing space in electric panels. It incorporates all electric motor protections and adapts to customer needs through its easy-to-install optional accessories.
• Optionally, a keypad, a communication interface or a motor PTC input can be added to the product.

SR33 Series will be discontinued once out of stock

SR33 series semi-conductor solid state soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors.

• 15.5 to 350A Rated Current Versions @ 208-230/460 VAC
• Five Trip Classes: Class 5, 10B, 10, 20, 30
• The SR33 series motor soft starters use thyristors for controlled reduced voltage motor starting and stopping, then switch to internal contacts for efficient running at the rated speed
• They are designed to fit in place of existing wye-delta starters.

Features

• 15.5 - 350A @ 208-230/460 VAC
• 24 VDC or 115 VAC I/O
• 24 VDC control power required
• Two-phase control
• Internal bypass contacts for Run
• Easily adjustable motor start voltage and start and stop times
• Suitable for a wide variety of motor loads
• Can replace wye/delta starters
• Fault indication of 4 or 7 fault types, depending upon model:
  SCR or Power Supply, Overheat, Control Power Supply,
  Bypass Relay Failure, Shearpin, Overload, Overcurrent
• IP20 (SR33-22 to SR33-97),
  IP00 (SR33-132 to SR33-482) panel mount
• Two-year warranty
