Type 2 "No Damage" Motor Starter Protection Component Protection — Low Voltage Motor Controllers It should be noted that these are basic short-circuit requirements. Higher, combination ratings are attainable if tested to an applicable standard. However, damage is usually allowed. 430.52 of the National Electrical Code ® allows dualelement, time-delay fuses and other overcurrent protective devices to be sized for branch circuit protection (short-circuit protection only). Controller manufacturers often affix labels to the inside of the motor starter cover which recommend the maximum size fuse for each overload relay size. A paragraph in NEC® 430.52 states: Motor Controller Protection The diagram below shows a Size 2, combination motor controller supplying a 460 volt, 3Ø, 20HP motor. The short-circuit withstand of this and other motor controllers are established so that they may be properly protected from short-circuit damage. Short-Circuit Protection of Motor Controller 40,000 RMS Symmetrical Available 3Ø, 460V 20HP M 3Ø, 460V 27 F.L.A. LOW-PEAK Dual-Element, Time-Delay Fuse ® Where maximum branch circuit short-circuit and ground fault protective device ratings are shown in the manufacturer’s overload relay table for use with a motor controller or are otherwise marked on the equipment, they shall not be exceeded even if higher values are allowed as shown above.** Typical Size 2 Controller There are several independent organizations engaged in regular testing of motor controllers under short-circuit conditions. One of these, Underwriter’s Laboratories, tests controllers rated one horsepower or less and 300V or less with 1000 amperes short-circuit current available to the controller test circuit. Controllers rated 50HP or less are tested with 5000 amperes available and controllers rated above 50HP to 200HP are tested with 10,000 amperes available. See the table below for these values.* Motor Controller HP Rating 1HP or less and 300V or less 50HP or less Greater than 50HP to 200HP 201HP to 400HP 401HP to 600HP 601HP to 900HP 901HP to 1600HP ** “Above” refers to other portions of 430-52 not shown here. This paragraph means that the branch circuit overcurrent protection for overload relays in motor controllers must be no greater than the maximum size as shown in the manufacturer’s overload relay table. These maximum branch circuit sizes must be observed even though other portions of 430.52 allow larger sizing of branch circuit overcurrent protection. The reason for this maximum overcurrent device size is to provide short-circuit protection for the overload relays and motor controller. Test Short-Circuit Current Available* 1,000A 5,000A 10,000A 18,000A 30,000A 42,000A 85,000A Type 1 vs. Type 2 Protection UL has developed a short-circuit test procedure designed to verify that motor controllers will not be a safety hazard and will not cause a fire. Compliance to the standard allows deformation of the enclosure, but the door must not be blown open and it must be possible * From Industrial Control Equipment, UL 508. 126 Component Protection — Low Voltage Motor Controllers to open the door after the test. In the standard short-circuit tests, the contacts must not disintegrate, but welding of the contacts is considered acceptable. Tests allow the overload relay to be damaged with burnout of the current element completely acceptable. For short-circuit ratings in excess of the standard levels listed in UL 508, the damage allowed is even more severe. Welding or complete disintegration of contacts is acceptable and complete burnout of the overload relay is allowed. Therefore, a user cannot be certain that the motor starter will not be damaged just because it has been UL Listed for use with a specific branch circuit protective device. UL tests are for safety, with the doors closed but do allow a significant amount of damage as long as it is contained within the enclosure. In order to properly select a branch circuit protective device that not only provides motor branch circuit protection, but also protects the circuit components from damage, the designer must look beyond mere safety standards. Coordination (protection) of the branch circuit protective device and the motor starter is necessary to insure that there will be no damage or danger to either the starter or the surrounding equipment. There is an “Outline of Investigation”, (UL508E) and an IEC (International Electrotechnical Commission) Standard IEC Publication 60947, “Low Voltage Switchgear and Control, Part 4-1: Contactors and Motor Starters”, that offer guidance in evaluating the level of damage likely to occur during a short-circuit with various branch circuit protective devices. These standards address the coordination (protection) between the branch circuit protective device and the motor starter. They provide a method to measure the performance of these devices should a short-circuit occur. They define two levels of protection (coordination) for the motor starter: Type 1. Considerable damage to the contactor and overload relay is acceptable. Replacement of components or a completely new starter may be needed. There must be no discharge of parts beyond the enclosure. Type 2. No damage is allowed to either the contactor or overload relay. Light contact welding is allowed, but must be easily separable. Where Type 2 protection is desired, the controller manufacturer must verify that Type 2 protection can be achieved by using a specified protective device. U.S. manufacturers have both their NEMA and IEC motor controllers verified to meet the Type 2 requirements outlined in UL508E and IEC 60947-4. As of this writing only current-limiting devices have been able to provide the current-limitation necessary to provide verified Type 2 protection. In many cases, Class J, Class RK1, or Class CC fuses are required, because Class RK5 fuses and circuit breakers aren’t fast enough under short-circuit conditions to provide Type 2 protection. Photo 1 Before Test: MCP as motor branch circuit protection for 10HP, IEC Starter with 22,000 amps available at 480V. Tables: Type 2 Motor Starter / Bussmann® Fuses On the following pages are motor starters of several manufacturers that have been verified by testing for Type 2 protection using the fuses denoted. These are maximum fuse sizes; for specific applications, it may be desirable to size closer. In some cases, the fuse type/ampere rating shown is greater than that permitted for branch circuit protection for a single motor per 430.52 (footnoted); however, the size may be applicable for group motor protection applications. In a few cases, the fuse type/ampere rating may be too small for typical motor starting applications (footnoted). It is recommended to use these fuse types/ampere ratings in conjunction with the fuse type/sizing philosophy (backup motor overload, optimal or maximum branch circuit protection - see Motor Protection Table explanation in Motor Circuit Protection Section of this book.) This data was obtained from the manufacturers or their web sites. Photo 2: Same as Photo 1, but during the test with MCP as the motor branch circuit protection. The heater elements vaporized and the contacts were severely welded. Extensive starter repair or total starter replacement would be required. This level of damage is permissible by UL508 or UL508E/IEC60947-4-1 Type 1 protection. The following pages have Fuse/Starter (IEC & NEMA) Type 2 “no damage” Tables for: General Electric Rockwell Automation/Allen-Bradley Square D Co. Siemens Cutler-Hammer Photo 3 During Test: same test circuit and same type starter during short-circuit interruption. The difference is current-limiting fuses provide the motor branch circuit protection. This illustrates the level of protection required by UL 508E and IEC 60947-4-1 for Type 2 “no damage” protection. The heaters and overload relays maintained calibration, which is extremely important to retain circuit overload protection. This starter could be put back into service without any repair. 127 128 to 132 133 to 134 135 to 136 137 to 138 139 to 141 MOTOR CONTROLLER AND FUSE SELECTION TABLE FOR TYPE 2 PROTECTION (UL & CSA VERIFIED) C O O R D I N AT E D PROTECTION Bussmann®/General Electric Co.
