PRODUCT DESCRIPTION Molded case circuit breakers are designed to provide circuit protection for low-voltage distribution systems. They are described by NEMA as,“. . . a device for closing and interrupting a circuit between separable contacts under both normal and abnormal conditions,” and furthermore as,“. . . a breaker assembled as an integral unit in supporting an PRODUCT HISTORY Originally a Westinghouse Product The need for molded case circuit breakers came about in 1918 when numerous applications for electrical motors resulted in a demand for a device that would ensure safe operation and, at the same time, protect electrical circuits. During this period, individual motors were used for the first time in industrial plants to operate machine tools and in private homes to operate appliances. Plant electricians were constantly changing fuses blown during motor start-ups because of the lack of properly designed fuses for motor circuit protection. Homes experienced similar problems when electrical circuits were overloaded. Inspectors were concerned about fire hazards because of plug fuses being bridged with pennies and the installation of fuses with too high of an ampere rating. Inspection authorities became involved and attempted to find a solution to the problem. Meetings with switch manufacturers were initiated in an effort to find a MAJOR PRODUCT INTRODUCTION 1923 1927 1939 March 2001 First compact, workable circuit breaker developed by Westinghouse enclosed housing of insulating material.” The NEC describes them as, “. . . a device designed to open and close a circuit by non-automatic means, and to open the circuit automatically on a predetermined overload of current, without injury to itself when properly applied within its rating.” Circuit breakers protect against overloads in conductors and protects against short solution. Switch manufacturers were asked to develop a switching device that would interrupt a circuit under prolonged overload conditions. The device would have to be safe, reliable and tamperproof. It should also be resettable so as to be reusable after an interruption without replacing any parts. This search for better circuit protection resulted in many different but unacceptable approaches to the problem. These early meetings and subsequent efforts prepared the groundwork for the eventual development of the molded case circuit breaker. After intensive research and development, Westinghouse produced the DE-ION arc extinguisher for use in large oil circuit breakers. Although too large in its initial form to be practical for small circuit breakers, the arc extinguisher was eventually modified into a usable size. The first compact, workable circuit breaker was developed in 1923 when the Westinghouse introduced the first complete circuit breaker line, rated 10-600 amps, 600 volts Along with ordering information and style numbers, the various maximum current ratings came to be known by frame designations: 50 Ampere E Frame 100 Ampere F Frame (Non-interchangeable Trip) 100 Ampere G Frame 225 Ampere K Frame 600 Ampere L Frame 1970 Motor Circuit Protector (”MCP“) introduced – First sensitive, low level protection designed specifically for motor circuits 1973 ”SELTRONIC“ introduced – First molded case circuit breaker with an electronic trip unit 1979 ”Current Limit-R Circuit Breaker“ introduced – First true current limiting circuit breaker 1995 ”OPTIM“ Family introduced – First truly programmable molded case circuit breaker 5 circuits in connected apparatus, such as motors and motor starters. Circuit breakers are designed for use in panelboards, switchboards, motor control centers, control panels, combination starters, individual enclosures, and bus duct plug-in units. modified arc extinguisher was coupled with a thermal tripping mechanism. It was not until four years later, however, that Westinghouse research engineers found the ideal combination of materials and design that permitted circuit breakers to interrupt fault currents of 5000 amperes at 120 volts AC or DC. One year later, Westinghouse placed the first circuit breaker on the market. Its acceptance was instantaneous. Since that initial introduction in 1927, Westinghouse continued to be at the forefront of circuit breaker technology with an unprecedented series of circuit protective enhancements and introductions as chronicled below. In 1994 the Eaton Corporation, another World Class technology leader, acquired the Westinghouse Distribution and Control Business Unit and integrated it with Cutler-Hammer forming a powerful, new combination, poised to meet the challenges of the next 100 years. 1920 1930 1940 1950 1960 1970 1980 1990 Present 1982 ”Series C“ Family introduced – New World Class standard meeting increasing interrupting requirements without sacrificing compact size 1994 MOLDED CASE CIRCUIT BREAKERS Westinghouse Distribution and Control Business Unit (DCBU) acquired by Eaton, integrated with Cutler-Hammer (The Cutler-Hammer line of molded case circuit breakers was sold when merged with Westinghouse) A
