Planning Software Makes Verification as per IEC 61439 Easy

The new IEC 61439-1/-2 standard for low voltage switchgear calls on switchgear manufacturers to provide more comprehensive documentation in terms of design certificates and performance characteristics than before. To this end, manufacturers are now given comprehensive support in planning and verifying standardized Ri4Power switchgear from Rittal in the guise of the new 6.0 version of the "Rittal Power Engineering" planning software.

Rittal has taken into account the demands of the new IEC 61439-1/-2 standard and offers the user comprehensive help in the new 6.0 version of the Power Engineering application. The main features of the new standard include extensive verification of the design of switchgear created by original switchgear manufacturer, as well as exact details of the rated currents of switching devices.

With Power Engineering, a suitable switching device can be selected - as early as the low-voltage switchgear preparation stage - that bears the current needed by the circuit. The protection category and the mounting location within the unit are also taken into account. Similarly, the software provides the appropriate design verification at the push of a button. The engineering tool offers check-lists, with which the switchgear manufacturer can check all the requirements that have to be considered during the planning and performance of the switchgear.

The software offers a blank form for the subsequent provision of individual evidence of items that must be compiled by every piece of switchgear. Check-lists included in the software also assist the manufacturer in conducting the tests needed to conduct and document the individual evidence of items.

Rittal Power Engineering supports users both with the Ri4Power modular system for low voltage switchgear, as well as with the low-voltage switchgear that consists of the TS 8 enclosure system and the RiLine60 modular busbar system.

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.
