Product Line Overview

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 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 Calibration

Special 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 Calibration

Add 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 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.

Freeze-Tested Circuit Breakers

The circuit breakers may be ordered

with freeze testing. This option uses

special lubrication and mechanical

operation is veriﬁed at -40°C.

Marine Applications

F-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 Certiﬁcations

Molded 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

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

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.
