Ex-Position Switchgear for Extreme Ambient Conditions

With the Ex ES 98 series, steute is proud to present a brand new generation of norm position switchgear in accordance with DIN EN 50041 for explosive environments. The products from this series come in a robust metal enclosure and in the future will be suitable for use in zones 1 and 2 (gas Ex) as well as 21 and 22 (dust Ex); a self-sufficient “Wireless Ex” version is also available. Users can choose from a large selection of actuators, and the range of switch inserts includes a new, flame-proof enclosure variant with three contacts, designed as a positive break snap action contact.

Additional features of the Ex ES 98 series are high protection classes (IP 66 to IP 69K) and an extended temperature range from -55°C up to +100°C. In addition, the devices can withstand high degrees of mechanical wear and tear, as shown by shock tests in the steute laboratory, for example. Tests in both our own laboratory and in independent institutes have also proven a high level of corrosion resistance, as well as a suitability for areas which are cleaned using high-pressure water jets and steam jets. With these features, the new series is suited to a wide variety of tasks in the field of automation – including and especially applications in unfavourable ambient conditions. A version for extreme applications without Ex protection standards is also available.

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.
