GE Energy Digital Energy Automatic Transfer Switch (ATS) Withstand and Closing Ratings (WCR) The Purpose of Testing and Unit Ratings GE automatic transfer switches (ATS) have been subjected to an extensive test program to show that they comply with and exceed UL 1008 standards as well as the various performance specifications used by most government agencies and major electrical engineers throughout the world. The primary test to assure the dependability of an automatic transfer switch is its ability to close into and withstand high fault currents. The purpose of this publication is to provide basic information on withstand ratings and to document the ratings that GE ATS currently holds under UL 1008. NFPA 110 Standard for Emergency and Standby Power Systems, Section 4-2.2, requires that the capacity and rating of automatic transfer switches be adequate to withstand the thermal and electromagnetic effects of short circuit currents that may arise in the electrical system. It is important to be able to compare properly the withstand close rating (WCR) of the switch to the available short circuit (fault) current of the system until the protective device clears the fault. If a transfer switch does not have adequate withstand capability—system failure, fire, injury to personnel or equipment damage may result. A clear understanding of the interrelationship between the protective device, transfer switch and system needs is necessary for a well designed installation. Some basic information on withstand rating terms and calculations follows the enclosed rating charts. Underwriters Laboratories (UL) is the independent testing body that has developed the standard UL 1008 which all major transfer switch manufacturers test to. UL lists products which have successfully passed a battery of witnessed tests including the withstand and close into fault tests described herein. Manufacturers that complete these tests are then permitted to label their products with the UL mark. UL made significant changes in April of 1989 regarding the labeling requirements of transfer switches. Prior to that date there had been concern over coordination with some protective devices. UL clarified the labeling procedure and now allows for three rating categories. • Current limiting fuse • Specific class (trip time) of molded case breaker • “Umbrella” or “Any Breaker” ratings that take into account all types of molded and insulated case circuit breakers; these tests are performed for a duration of 3 cycles on units 225 amps and greater, and for 1.5 cycles on 40-150 amp units (with an optional 3 cycle duration for units up to 150 amps; note the three cycle rating on 150 amp and below units is optional as UL has determined that all breakers in this size clear in less than 1.5 cycles). The “Umbrella” or “Any Breaker” rating is therefore the actual UL requirement and definition of the ATS industry 3 cycle (or 1.5 as noted) withstand and closing rating, and should not to be confused with additional, non UL 1008 labeled “withstand only” tests. TB-11102 Page • TB-(2/11 1102) Zenith Product Ratings The GE family of transfer switches have maintained an industryleading role in ratings from the time of its introduction. Today all ZTS and ZTE products are labeled with an “umbrella” (any molded case breaker) rating as well as some higher specific breaker levels giving the consultant a free hand with system design. The following pages include the UL certified ratings and specific breaker coordination charts, withstand rating data and additional specific information. The consulting engineer must keep in mind that unless a transfer switch bears an umbrella breaker approval for use with any molded case breaker, care must be taken to assure that the breaker specified for the installation have an equal or shorter trip time when compared to the listed devices. This would limit the application of the switch to projects within the scope of its specific breaker listing. In addition to this factor, many transfer switch manufacturers perform additional withstand tests on selected products. These additional tests may be either for a higher current valve or a longer duration than their standard UL listed ratings. The consultant must determine the applicability of these tests and take careful note of the fact that these levels are normally not UL labeled ratings.

Too often a switch is rated by a manufacturer in one set of WCR terms and the available system fault currents described with a different set of terms. The purpose of this paper is to outline the different ways switches may be rated (WCR) and systems are measured. As fault currents can occur at any level, a transfer switch must be capable of withstanding any fault current up to its maximum rating. This rating is based on the rating of the protective device in front of the unit and must be considered on that basis. Basic Definitions a. RMS Current – The Root Mean Square which is the effective value of an alternating current. It is equal to .707 of the peak current for a sine wave. This is the value referred to when people say “current.” b. Peak Current – The instantaneous maximum value of current— the peak current of a sine wave is 1.414 times its RMS value. c. Symmetrical Current – The alternating current which is symmetrical around the zero axis of the sine wave. d. Asymmetrical Current – The alternating current which is not symmetrical around the zero axis. e. Peak Fault Current – The instantaneous maximum current value that occurs after the start of a fault in any phase. f. Available Peak Current – Maximum possible short circuit current that may exist in a system without protective devices. g. Peak Let Through Current – Maximum instantaneous current through the protective device during the total clearing time. h. Withstand Current Rating – The rating that defines the ability of the switch to withstand the thermal and electromagnetic effects of short circuit currents for a set period of time. i. Withstand and Closing Rating (WCR) – UL 1008 test for a transfer switch’s ability to close into and withstand a fault current. These are the ratings which will actually appear on the UL label of the product. NOTE: For diagrams of typical current wave forms, see Figure 1 and Figure 2. The following values have all been used to describe identical circuit conditions: Available Short Circuit Current RMS Peak Let Through Current (½ cycle) Peak Asymmetrical Current Peak Symmetrical Current Withstand Rating 3 Cycles RMS 120,000 amps 130,000 amps 156,000 amps 140,000 amps 128,000 amps What do these numbers mean? They mean that a switch was tested at 28,000 amps RMS Sym for 3 cycles; the switch also had a projected peak symmetrical current of 40,000 amps for less than ½ cycle and a peak asymmetrical current of 56,000 amps for less than ½ cycle. The switch has been tested in a system that has an available capacity of 120,000 amps RMS. How should a manufacturer rate a switch? Preferably by submitting test data which is reported as outlined by UL 1008 specifications. This data calls for RMS symmetrical readings based on specific test parameters. Other figures may be misleading. TB-1102 • Page 4 Interrupting Ratings Some manufacturers of circuit breaker type automatic transfer switches list interrupting current (IC) ratings in lieu of WCR. These switches will then open on faults instead of withstanding the fault until the external protective device clears. As the transfer switch is then used to open the fault current in place of a protective device—this may leave the transfer switch with both normal and emergency open which then requires manual resetting of the breakers within the transfer switch enclosure. The circuit breakers may require factory inspection after high current interruption in accordance with common circuit breaker procedures. WCR ratings, as opposed to IC ratings appear to offer a better choice to the system designer as he attempts to coordinate the protection of the entire system. Knowing the maximum amount and duration of fault current a switch will withstand gives the designer the information necessary for complete coordinated system design. Advantage of RMS Symmetrical Ratings a. Date is consistently reported based on UL test procedures. b. Where time beyond the first ½ cycle is given suitable decisions can be made to use circuit breakers or fuses. c. Misleading reporting is eliminated. Blow-On Effects on Short Circuit Current in Contacts Comparison of Terms a. b. c. d. e. GE tests show results based on various current values and time durations, and include additional high current tests with fuses. By considering this range of values, it is possible to predict performance with different fuse characteristics or specific circuit breaker currenttime curves with a given available short circuit current. Some switch designers analyze “blow-on” and “blow-off” effects and force vectors (due to electromagnetic repulsion) to claim increased WCR capability of their product. Such calculations are very rough approximations because of inherent errors in estimating “domain” size and number, current “pinch” effect and the problem of complex geometry of actual contact structures when compared to idealized models. The only proof of a successful design are tests, uniformly performed and consistently reported all to the same criterion such as UL 1008. Definitions & Calculations Available Fault Current Available fault current information can often be supplied by the utility company. If this information is not available, approximate fault current can be calculated by knowing the transformer impedance (usually 2 to 5% of full load ampere rating of the transformer). Figure 1 Symmetrical and Asymmetrical Waves For a single phase system, transformer let through current is: (where Z is transformer impedance in percent divided by 100) kVA (of trans) x 1000 I = Z x Line Volts For three phase systems: kVA x 1000 I = 1.73 Z x Line Volts Figure 2 Current Limiting Fuse Effects EXAMPLE: 500 kVA transformer 2.5% Impedance 480 Volts, 3 phase 500 x 1000 1.73 (.025) (480) = 24,085 amps This figure is somewhat lower if a long run of cable introduces a substantial volt drop. Available fault current determine the WCR rating that a transfer must meet.

Representatives can provide you with field service, equipment parts and preventive maintenance. Because emergency power systems are required to operate under the most adverse circumstances, site personnel may be called upon at any time to make decisions regarding the operation of the system, therefore training of these personnel is critical to the future of any installation. GE offers a variety of training options including on-site classes for project personnel, factory instruction on your equipment prior to shipment and service schools covering transfer switches and switchgear systems. Product Overview When you purchase emergency power equipment, reliability and quality are a necessity. GE is committed to providing the highest level of quality demanded by the industry. Our complete product line will allow you to specify a total power management system while maintaining overall compatibility and the most comprehensive warranty in the industry. Commitment to the Customer All team members at GE are aware of the critical situations in which our products are called upon to perform. With that understanding comes an obligation beyond merely fulfilling an order or turning out a product. Serving that obligation is our mission at GE. GE’s team works with you from the first phone call through completed start-up. Then, working hand in hand with the consulting engineer, the contractor and the facility owner/operator, we’ll ensure that the system fulfills both current and future needs. “Commitment to our customer” has been GE’s driving force for more than 100 years in the power control industry. This same sense of purpose and responsibility will continue as we address future power control challenges.
