Intelligent Soft Starts are rated up to 900 A and 750 hp.

Press Release Summary:




RSQK Series delivers smooth and step-less accel/decel for decreased mechanical transmission component wear as well as reduced starting currents and mechanical stress on gears, shafts, and pulleys. Intended for industrial applications exceeding 100 hp, products can be connected inside motor delta and incorporate automatic energy optimization as well as application setup features. UL listed range is 23-900 A @ 230 and 480 Vac, and max UL motor rating at 460 Vac is 750 hp.



Original Press Release:



High Power Intelligent Soft Starts up to 900 Amps / 750Hp



Buffalo Grove, IL - Carlo Gavazzi has recently launched their RSQK Series high power intelligent soft starts, which are designed to improve performance of industrial applications. They decrease of the "wear and tear" of mechanical transmission components (such as belts) and assure the reduction of high starting currents and of mechanical stress on gears, shafts and pulleys, thanks to a smooth and step-less acceleration and deceleration. While Variable Frequency Drives (VFDs) have a strong market share in the low power range (0.5 to 5HP), RSQK soft starts are the perfect solution for industrial applications in higher power range (>100Hp). The cost advantage of this new device, compared to VFDs, raises as it can be connected inside the motor delta. In this way, a smaller soft start can be used for the same motor rating. Furthermore, the RSQK Series features are well suited for applications such as controlling large pumps, fans and mixers in 200-500 HP range, that generally require only a limited number of starts and stops. Compared to other soft starts, the RSQK Series soft starts are provided with an automatic energy optimizing feature that can successfully increase efficiency, especially in lightly loaded applications, thus saving energy without any drawbacks on the motor or system. The device is also provided with an automatic application setup, thus guaranteeing lower installation costs and quicker commissioning. Some key technical specifications include:

  • 3-phase controlled soft start with internal bypass
  • UL listed range: 23-900 Amps at 230 and 480VAC
  • Automatic energy optimizing feature
  • 6-button keypad with LCD display for continuous display of relevant parameters
  • Motors, resistive (heater) control and inductive (transformer) loads
  • In-line or inside delta wiring operation capability
  • Maximum UL motor rating at 460VAC: 750 horsepower
  • Up to 12 starts per hour
  • History of last 5 trips
  • Optional Modbus and remote keypad operation for multiple soft start control
  • cULus listed and CE marked

    The RSQK Series is available from Carlo Gavazzi's North American network of sales offices, distributors or www.GavazziOnline.com.
