Global Third-Party Certification Certification marks ensure product compliance with the total standard via the third party witnessing of tests by globally recognized independent certification organizations. KEMA is a highly recognized, independent international organization that offers certification and inspection facilities for equipment in many industries. The KEMA-KEUR mark is the highest certification an electrical product can receive from KEMA. Our IEC Molded Case Circuit s are KEMA tested and certified. These breakers are also listed in accordance with UL 489, as well as CSA C22.2 No KEMA, UL and CSA provide ongoing follow-up testing and inspections to ensure that Cutler-Hammer Molded Case Circuit s continue to meet their exacting standards. General Information Eaton s electrical business, under the Cutler-Hammer brand, offers the widest variety of molded case circuit breakers available today. Designed for electrical and machinery OEMs serving a range of industries and applications, these proven designs incorporate the latest in innovation with the high reliability that has been our hallmark since the advent of the circuit breaker in the 19s. The Series C family ranges from 15 2 amperes, and includes thermalmagnetic breakers, electronic trip breakers, molded case switches, motor circuit protectors, and specially designed breakers for Engine Generator, DC and mining applications. The new Series G line features an average % size reduction, common field-installable internal accessories, and advanced trip unit functionality that eliminates the need for rating plugs. These breakers meet the requirements of UL, CSA, IEC, CCC and CE, allowing the OEM to standardize on a design that meets the needs of their global customer base. CA081E

6 July 07 5 Amperes -5 Line and Load Terminals Eaton s Cutler-Hammer line and load terminals provide wire connecting capabilities for specific ranges of continuous current ratings and wire types. All terminals comply with Underwriters Laboratories Standards UL 486A and UL 486B and CSA Standard C22.2 No. M. Unless otherwise specified, circuit breaker line and load terminals are shipped separately for field installation. The wire connecting terminal is secured with two pan-head, slotted screws and lockwashers which can be checked for the correct torque loading or retightened from the front of the circuit breaker before installation of the conductors. (Applies to all styles.) The circuit breaker line/load terminal conductors are positioned in the conducting holes in the wire connecting terminal and are secured with recessed socket screws which are tightened to the correct torque loading from the front of the circuit breaker. Ordering Information circuit breakers use Cu/AI terminals as standard. When optional copper terminals are required, order by. Specify if factory installation is required. Table -4.
