Eaton Introduces Smartwire-DT Interface Module

Eaton has introduced a Smartwire-DT interface module for its range of PKE electronic motor protection circuit breakers. This is enabling the company to offer a full range of networked motor starter solutions for control panels, which use only standard components from the xStart family. Eaton's approach to networked starter solutions is said to bring benefits including competitive pricing on standard devices and the elimination of the need for system builders and end users to stock different ranges of devices for traditionally wired and networked panels.

Eaton's Smartwire-DT system has been designed to make the benefits of the fieldbus available inside the control panel. It eliminates all conventional control wiring in the panel, with connections instead made by convenient plug-in daisy-chain cables. This reduces the time needed to wire the panel and makes incorporating future modifications quick and easy. Standard contactors and protection devices in the xStart range are made ready for Smartwire-DT connectivity by adding an interface module in the same way that an auxiliary contact block is fitted.

The interface modules for PKE motor protection circuit breakers give users of Smartwire-DT access to versatile electronic motor protection. Each of the units in the PKE series covers a range of motor currents, thereby minimising the number of variants that have to be stocked, and the units also offer tripping classes that can be set from Class 5 to Class 20, which mean that optimum protection can be provided for all types of drive, irrespective of the start-up conditions.

Other benefits of PKE motor protection circuit breakers are said to include: reduced heat dissipation and energy losses compared with devices that use conventional bimetal protection elements; high accuracy and stability; and the ability to transfer data, including real-time current flow information, to a PLC or similar external device.

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

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

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.
