Product Line OverviewVol. 1, Ref. No. [0468]

Product Line DescriptionCutler-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 inter-rupting 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 con-nected 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 CalibrationSpecial non-UL-listed calibrations are available for certain ambient temperatures other than 40°C and for frequencies other than 50/60 Hz or DC. Reduced interrupting ratings will apply for 400 Hz applications. Maximum thermal calibration is limited to 135A at 400 Hz.

50°C CalibrationAdd suffix V to Catalog Number for complete breaker, listed above, when ordering listed ampere ratings for breakers to be used in 50°C ambients.

Moisture-Fungus TreatmentAll 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.

Freeze-Tested Circuit BreakersThe circuit breakers may be ordered with freeze testing. This option uses special lubrication and mechanical operation is verified at -40°C.

Marine ApplicationsF-Frame circuit breakers can be sup-plied 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 50°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 65 feet in length. Requirements include 40°C ambient calibration, spe-cial labeling, and no use of aluminum conductors or terminals.

UL 489 Supplement SB requires 50°C ambient calibration, vibration testings, special nameplating and no use of aluminum conductors or terminals.

Standards and CertificationsMolded case circuit breakers are designed to conform with the follow-ing standards:

■ Underwriters Laboratories, Inc., Standard UL489, Molded Case Circuit Breakers and Circuit Breaker Enclosures

■ National Electrical Manufacturers Association Standards Publication No. AB1-1993, Molded Case Circuit Breakers

■ Australian Standard AS 2184, Molded Case Circuit Breakers

■ British Standards Institution Standard BS 4752: Part 1, Switchgear and Control Gear Part 1: Circuit Breakers

■ Canadian Standards Association Standard C22.2 No. 5, Service Entrance and Branch Circuit Breakers

■ International Electrotechnical Commission Recommendations IEC 157-1, Circuit Breakers

■ Japanese T-Mark Standard Molded Case Circuit Breakers

■ South African Bureau of Standards, Standard SABS 156, Standard Specification for Molded Case Circuit Breakers

■ Swiss Electro-Technical Association Standard SEV 157-1, Safety Regula-tions for Circuit Breakers

■ Union Technique de l’Electricite Standard NF C 63-120, Low Voltage Switchgear and Control Gear Circuit Breaker Requirements

■ Verband Deutscher Elektrotechniker (Association of German Electrical Engineers) Standard VDE 0660, Low Voltage Switchgear and Control Gear, Circuit Breakers

Conformance with these standards satisfies most local and international codes, assuming user acceptability and simplified application.

Molded case circuit breakers equal or exceed Federal Specification Classifi-cation W-C-375b requirements for the particular class associated with the cir-cuit breaker frame being considered.

Molded Case SwitchesMolded Case Switches are used ascompact switches in applicationsrequiring high current switchingcapabilities. Molded case switchesare constructed of circuit breakercomponents and are of the highinstantaneous automatic type. Moldedcase switches are listed in accordancewith Underwriters Laboratories, Inc.,Standard UL 1087.

Line and Load TerminalsLine and Load Terminals provide wireconnecting capabilities for specificranges of continuous current ratingsand wire types. Except as noted,terminals comply with UnderwritersLaboratories, Inc., Standards UL486Aand UL486B. Unless otherwisespecified, F-Frame circuit breakersare factory equipped with loadterminals only.

Ordering InformationF-Frame circuit breakers and moldedcase switches have load terminalsonly as standard equipment. Whenstandard line-end terminals (same asstandard load-end terminals) arerequired, add Suffix L to the circuitbreaker Catalog Number. When non-standard or optional line and/or loadterminals are required, order by stylenumber. Specify if factory installationis required.
