-2 Product Line Overview January 1 Vol. 1, Ref. No. [0468] Product Line Description Cutler-Hammer 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 a supporting and enclosing 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. So designed, Cutler-Hammer circuit breakers protect conductors against overloads and conductors and connected apparatus, such as motors and motor starters, against short circuits. In low voltage distribution systems, there are many varied applications of molded case circuit breakers. Cutler-Hammer offers the most comprehensive family of molded case circuit breakers in the industry. This family of circuit breakers includes: Thermal Magnetic Trip Breakers Electronic rms Trip Breakers Molded Case Switches Motor Circuit Protectors Current Limiting Breakers Special Application Breakers World Breakers Special Calibration Special non-ul-listed calibrations are available for certain ambient temperatures other than C and for frequencies other than / Hz or DC. Reduced interrupting ratings will apply for 0 Hz applications. Maximum thermal calibration is limited to 1A at 0 Hz. Suffix H01 0 Hz % Adder Moisture-Fungus Treatment All circuit breaker cases are molded from glass-polyester which does not support the growth of fungus. Any parts which are susceptible to the growth of fungus will require special treatment. Suffix J01 Fungus Treated Freeze-Tested Circuit Breakers The circuit breakers may be ordered with freeze testing. This option uses special lubrication and mechanical operation is verified at - C. Suffix F01 Freeze Tested Marine Applications circuit breakers can be supplied to meet the following marine specifications: U.S. Coast Guard CFR 46 ABS American Bureau of Shipping IEEE 45 These specifications generally require molded case circuit breakers to be supplied with C ambient calibration, special nameplating, and plug-in adapter kits. When plug-in adapter kits are used, no terminals need be supplied. Circuit breakers can also be supplied to meet UL489 Supplement SA (Marine Use) and UL489 Supplement SB (Naval Use). UL489 Supplement SA applies to vessels over feet in length. Requirements include C ambient calibration, special labeling, and no use of aluminum conductors or terminals. Suffix H08 Marine UL 489 Supplement SB requires C ambient calibration, vibration testings, special nameplating and no use of aluminum conductors or terminals.

January 1 Vol. 1, Ref. No. [0489] s -23 Molded Case Switches Molded Case Switches are used as compact switches in applications requiring high current switching capabilities. Molded case switches are constructed of circuit breaker components and are of the high instantaneous automatic type. Molded case switches are listed in accordance with Underwriters Laboratories, Inc., Standard UL 87. Line and Load Terminals Line and Load Terminals provide wire connecting capabilities for specific ranges of continuous current ratings and wire types. Except as noted, terminals comply with Underwriters Laboratories, Inc., Standards UL486A and UL486B. Unless otherwise specified, circuit breakers are factory equipped with load terminals only. Ordering Information circuit breakers and molded case switches have load terminals only as standard equipment. When standard line-end terminals (same as standard load-end terminals) are required, add Suffix L to the circuit breaker. When nonstandard or optional line and/or load terminals are required, order by style number. Specify if factory installation is required. Table -37.
