Eaton Improves System Reliability by Expanding Motor Protection Capabilities with Broader Range of Electronic Overload Relays

Diversified industrial manufacturer Eaton Corporation is improving system reliability for industrial customers by expanding its C440 and XT electronic overload relays and providing motor protection at higher amperages. Designed for global applications, the wider range of electronic relays provide an integrated starter solution and eliminate the need for an external current transformer (CT), reducing overall space and equipment requirements.

“Eaton is helping customers advance lean processes through a range of innovative industrial control solutions that simplify control and reduce equipment and space requirements,” said Raza Durrani, product manager at Eaton. “The expanded electronic overload relay solutions improve system reliability for industrial customers.”

Eaton’s electronic overload relays are now available up to 175 ampere (A) and feature integral ground fault protection and communications capabilities in a single, compact device. With a universal design, the electronic overload relays provide an integrated starter solution for applications requiring National Electrical Manufacturer Association (NEMA) size 4 and 185A International Electrotechnical Commission (IEC) contactors. Additionally, the new frame is available in cable-in/cable-out and pass-through versions, making it well suited for upgrading existing customer infrastructure.

With a patented, compact design, Eaton electronic overload relays are easy to install, maintain and configure. A light-emitting diode (LED) display on the device provides easy-to-see indication of device status and fault indication, allowing maintenance personnel to quickly determine if the device and motor are operating appropriately.

Customers can select the motor protection features they need, with selectable trip class, ground fault detection, phase imbalance and full load current (FLA) adjustment (5:1). Further, the C440 and XT overload relays can integrate into plant management systems, allowing network monitoring and providing asset protection. Eaton C440 and XT overload relays feature integral communications capabilities, which allow the relays to easily integrate with customers’ preferred industrial network. DeviceNetTM, PROFIBUSTM, Modbus®, Modbus TCP, Ethernet/IP communication protocols are supported.

Designed for global applications, the electronic overload relays meet Underwriters Laboratories (UL), Canadian Standards Association (CSA) and Conformité Européenne (CE) standards. Additionally, the solid-state overload relays are Restriction of Hazardous Substances (RoHS) compliant.

Eaton’s electrical business is a global leader in power distribution, power quality, control and automation, power monitoring, and energy management products and services. Eaton is positioned, through its Cutler-Hammer®, Moeller®, Powerware®, Holec®, MEM®, and Santak® global electrical product series, to answer today’s most critical electrical power management challenges.

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.
