Digital Multimeter for Low-Voltage Installations

The AVO410 digital multimeter from Megger is suitable for use in any location on all types of low-voltage electrical installations, including industrial installations. It combines rugged yet compact construction with ease of use and a CAT IV 600V safety rating in line with IEC 61010, Small enough to fit easily into the palm of the hand yet tough enough to withstand the rigours of regular use in demanding environments, the AVO410 measures DC voltage to 1,000V, AC voltage to 750V, and AC or DC current to 10A.

All AC ranges are true RMS. In addition, the instrument offers resistance, frequency and capacitance ranges, as well as continuity and diode test functions. A min/max feature is provided that allows users to switch between minimum and maximum measurements, making it unnecessary to continuously monitor the display to observe momentary fluctuations in readings. A data hold function is also provided, which allows the display to be temporarily frozen. The AVO410 multimeter has been designed to be intuitive to use and easy to operate, even with a gloved hand.

Functions are selected with a large clearly marked rotary switch and pushbuttons, and the results are shown on high-contrast backlit display that is easily read even in poor lighting conditions. When first selected, all functions are auto-ranging but manual range selection, which can be advantageous in some applications, is also supported. The versatility of the AVO410 is further increased by the provision of a serial port that can, with the aid of a suitable lead, be connected to the USB port of a PC.

Using software that is available from Megger as an optional accessory, measurements can be captured direct from the instrument, allowing it to function as an inexpensive data logger. For use in this mode, the auto-off function, which normally operates after 10min of inactivity, can be disabled. AVO410 compact digital multimeters from Megger are supplied complete with test leads and probes. The leads are made from extra-flexible cable with heat-resistant silicone rubber insulation, and the probes have GS38 compliant shrouded tips.

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.
