High Power Intelligent Soft Starts

Carlo Gavazzi is pleased to announce the arrival of the RSQK Series High Power Intelligent Soft Starts, which are designed to improve performance of industrial applications up to 900 Amps / 750 Hp. They decrease the “wear and tear” of mechanical transmission components (such as belts) and reduce the high starting currents and mechanical stress on gears, shafts and pulleys, thanks to smooth and step-less acceleration and deceleration. These soft starts are the perfect solution vs. variable frequency drives for industrial applications in higher power range (>100Hp).

The RSQK Series features are well suited for applications such as controlling large pumps, fans and mixers starting at the 200Hp 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 cUL motor rating at 460VAC: 750 horsepower
  •     Up to twelve starts per hour
  •     History of last five trips
  •     Optional Modbus and remote keypad operation for multiple soft start control
  •     cULus listed and CE marked

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
