Eaton’s New Bussmann Series NH Size Fuses Provide the Industry’s Highest Current Density and Consistent Bolt-Hole Pattern

Power management company Eaton today introduced its new Bussmann series 1000 volts direct current (Vdc) NH size photovoltaic (PV) solar fuses specifically designed for protecting and isolating array combiners, re-combiners, disconnects and inverters. With the industry’s highest current density and two available mounting options, the NH PV fuses provide design flexibility in a compact size.

Eaton’s NH PV fuses meet global agency standards, simplifying designs for worldwide markets, and are available in traditional blade and bolt-on versions. The traditional blade version can be used with a fuse block to provide quick, tool-less replacement for easy maintenance. The bolt-on version can be bolted directly to a bus bar, reducing components and assembly time. With a common bolt pattern, the NH PV fuses are designed to easily integrate into a standardized bus bar design, regardless of fuse ampacity.

“Eaton delivers a range of overcurrent protection devices for solar applications that protect valuable balance of system equipment and support uptime,” said Kevin Calzada, product manager, solar fuses, Eaton’s Bussmann Division. “Our latest NH fuses for PV applications maintain Eaton’s industry-leading efficiency and low-operating temperatures.”
Both fuse versions come with system monitoring accessories that provide dual visual indication and optional microswitches (for traditional blade version only) to make it easier to monitor system processes.

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.
