GRP Enclosures Resist Chemical Corrosion

Spelsberg has extended its enclosures range with a new line of heavy-duty glass reinforced polyester (GRP) products, suitable for use in harsh industrial environments. The GRP enclosures are offered in a range of sizes and boost application flexibility through a range of accessories and the possibility of CNC modifications, as well as a host of customisation possibilities. Spelsberg's heavy-duty GRP enclosures are designed to provide effective corrosion resistance for electrical and electronic controls in the harsh environments typical of the marine, offshore, petrochemical, paper and water-treatment industries.

Sealed to IP65 to protect against the ingress of dust and liquids, the GRP enclosures offer a robust construction with features such as an integral drip shield, to direct liquids away from the door shield. Spelsberg claims that GRP offers a high level of rigidity at minimal thicknesses, equating to increased protection for a wide range of housed equipment and instrumentation, but in a lightweight design. The enclosures are available in seven standard sizes, from 250 x 300 x 170mm up to 810 x 1,060 x 350mm. Doors can be left or right mounted and the hinging allows door opening to up to 240deg for ease of access into the enclosure.

Options include key locks for added security and a stylised window door providing easy visual inspection of interior components. This window is made from impact-resistant 3mm polycarbonate, permanently bonded in place to maintain the IP65 sealing. For extra flexibility, Spelsberg offers a wide range of accessories for the enclosures, including mounting plates, inner doors and modular kits, which can be readily installed using the moulded-in mounting rails. Spelsberg also offers in-house CNC modification and a full customisation service, enabling enclosures to be tailored to meet specific application requirements.

Modifications can include anything from milling, drilling and engraving to custom cable entries, brand logos or simple instructions. The customisation service allows the GRP enclosures to be supplied fitted with DIN rails, bus bars, electrical components, clip-on terminals and more.

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.
