40、des information for selecting the proper circuit breakerfor a particular application. This recommended practice helps the application engineerspecify the type of circuit breaker, ratings, trip functions, accessories, acceptance tests,and maintenance requirements. It also discusses circuit breakers f

41、or special applications,e.g., instantaneous only and switches. In addition, it provides information for applyingcircuit breakers at different locations in the power system and for protecting specificcomponents. Guidelines are given for coordinating combinations of line-side and load-side devices. Ac

42、ceptance testing and maintenance guidelines are provided so that reliableoperation can be verified and maintained.This recommended practice does not cover the selection and application of circuitbreakers such as marine circuit breakers and definite purpose circuit breakers.1.2 Two classifications of

43、 breakersThere are two main classifications of low-voltage circuit breakers: molded-case circuitbreakers and low-voltage power circuit breakers. Within the molded-case circuit breakerclassification, there is another type of circuit breaker called the insulated-case circuitbreaker. The construction a

44、nd characteristics of these three types will be discussed.Throughout the balance of this recommended practice, these devices will be referred to asfollows: MCCB: molded-case circuit breaker ICCB: insulated-case circuit breaker LVPCB: low-voltage power circuit breakerEach one of these circuit breaker

45、s has different design characteristics and, in many cases,different application requirements.IEEEStd 1015-2006 CHAPTER 12 Copyright 2006 IEEE. All rights reserved.This recommended practice compares the different types of circuit breakers so that thepower systems engineer can decide which one is best

46、 suited for a particular application. Inaddition, it discusses ratings, such as overload, short-time, and interrupting capabilities.Protection requirements depend on the circuit breaker location in the power system as wellas the type of equipment that is being protected. Examples for different types

47、 ofequipment and circuit locations are discussed in this recommended practice.MCCBs are tested and rated in accordance with UL 489-2002.1Their current-carryingparts, mechanisms, and trip devices are completely contained within a molded case ofinsulating material. The cover and base of smaller MCCBs

48、are designed so that theMCCBs cannot be opened for maintenance purposes. The main contacts of MCCBscannot be removed; however, some MCCBs are available with field-installableaccessories. MCCBs are available in stationary or plug-in construction with circuit-breaker enclosures that can be flush or su

49、rface mounted. They are available in a largenumber of continuous-current and interrupting ratings. The smaller continuous-currentratings are equipped with thermal-magnetic or magnetic only trip units. Larger sizes arealso available with thermal-magnetic or electronic (static) trip devices.ICCBs are also tested and rated in accordance with UL 489-2002. As with MCCBs, ICCBcurrent-carrying parts, mechanisms, and trip units are contained within a molded case ofinsulating material. The case is designed so that it can be opened for inspection of contactsand arc chu
