NEMA v/s IEC Standards Course Content The motor standards can be grouped into two major categories: NEMA and IEC (and its derivatives). This includes standard full NEMA sizes and motor matched half sizes exclusive to Siemens. Our IEC Combination Starters include direct-on-line, reversing, and two-speed operating modes. Sizes 1–8 are 24/60 only. This helps ensure a quick reaction to power issues, which reduces downtime and maintenance expenditures by protecting motors. OEMs like this approach because they can more closely match contactors to the load than with NEMA, which can save space and money. Eaton's IEC-rated starters provide you with the ability to select the motor starting equipment that is specific to your needs. There are four basic motor control options available: Basic contactors, traditional starters, manual motor starters, or combination starters. etration of solid objects, whereas the second states the motor’s degree of protection against water. Additionally, the Manual Motor Starters . In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors"). Size 0–2 non-fusible combination starters can be converted to a fusible type. Ratings For Coils. Square D 8502 Sgo 2 Size 5 Motor Contactor Sz5 480v Coil 200hp. How to Select and Size an IEC Contactor. IEC manual motor starters are electromechanical protection devices. The chart below displays information for motor wire size, breaker size, thermal overload ratings, and other data for three-phase AC motor circuit protection. Written by Kupis on May 21, 2020 in Chart. Purchased products. There is a wide range of motor controls available that meet one of the two dominant standards: National Electrical Manufacturers’ Association (NEMA) ICS 2 and International Electrotechnical Commission (IEC) 60947. For either higher output and larger size motors and/or other speeds or voltages, please contact our Special Products Department. Both also have standards in place to designate: Frame size dimensions; Minimum efficiency levels; Testing methods; Despite the similarities, electrical and mechanical expectations in the market are sometimes different. 53 Classification and Types of Wiring NEMA has established two classification standards (Class I and Class II) and three types of wiring (A, B, and C) used in the construction of motor control centers. Download as PDF. The end of the motor is defined in the IEC-standard as follows: • The D-end is normally the drive end of the motor. 480v Motor Starter Size Chart.
