Product Description

Internal Accessories

Alarm LockoutThe alarm switches operate when the circuit breaker is tripped by a short cir-cuit or overcurrent, but also when it is tripped by a shunt trip or undervoltage release.

Auxiliary SwitchesAuxiliary switches are used for signaling and control purposes. The various functions of the auxiliary switches (changeover) are shown in Figure 2.

Shunt TripsThe shunt trip is used for remote tripping.

The coil of the shunt trip is rated only for short-time operation.

It is not permissible with the circuit breaker open to apply a continuous opening command to the shunt trip in order to prevent the breaker from closing. This means that interlocking circuits with continuous commands may not be set up with shunt trips.

Undervoltage ReleasesThe circuit breaker cannot be closed until the undervoltage release is ener-gized. If the release is not energized, the circuit breaker can only perform an idle switching operation.

Frequent idle switching actions should be avoided as they shorten the endur-ance of the circuit breaker.

Earth Leakage(Ground Fault) Modules

LG Breaker with Earth Leakage Module(4-Pole Breaker Shown)

For low-level, coordinated ground fault protection, IEC and UL-rated earth leakage modules are available for LG breakers. The module does not restrict the use of other breaker accessories. The LG module is bottom mounted for

circuits up to 400 and 630 amperes.The module is completely self-contained since the current sensor, relay and power supply are located inside the product. Current pick-up settings are selectable from 0.03 – 30 amperes for the UL rated modules, and 0.03 – 10.0 amperes for the IEC modules. Time delays are also selectable from instantaneous – 1.0 sec-onds for 0.10 ampere settings and above. A current pick-up setting of 0.03 amperes defaults to an instantaneous time setting regardless of the time dial’s position. Two alarm contacts come as standard: a 50% pretrip and a 100% after trip, both based only on earth leakage current levels.

Flange Mounted Handle Mechanism

The Flex Shaft™

Flange Mounted handle mechanisms mount on the flange of an enclosure door. The Flex Shaft is an extra heavy-duty mechanism that includes a flexible shaft in various lengths, 3 feet (0.9 m) through 10 feet (3 m) for use with various size enclosures.

The Flex Shaft handle will accept up to three padlock shackles, each with a maximum diameter of 3/8 inch (9.5 mm). Can be used with NEMA 12/3R fabricated enclosures. An optional handle is available for Flex Shaft that is suitable for use with NEMA 4/4X environments.

The Flex Shaft comes preset from the factory, requiring only minor field adjustments on installation, which takes about 10 minutes — a significant time savings compared to installation of other types of flange handle mecha-nisms. The Flex Shaft mechanism also takes up less interior enclosure space than competitive designs and the han-dle fits standard flange cutouts. Flex Shaft handle can be remotely mounted from breaker, where an operator can use it by “funneling” the cable through conduit.

Flex Shaft is UL listed under File E64893 and meets CSA requirements.

Table 21. Flex Shaft Ordering Information

Note: NEMA 4/4X handle mechanisms are available. Add Suffix X to complete Catalog Number.

Add Suffix L to complete Catalog Number for 6-inch (152.4 mm) handle.

Original narrow handle design (No C Suffix) is available. Remove C from Catalog Number.

Note: When selecting the length of shaft, ensure minimum bending radius of 4 inches (101.6 mm) is maintained to operate properly.

The standard method of shipment includes the mechanism preset at the factory; however, minor field adjust-ments may be required.

Rotary Handle

The Cutler-Hammer Rotary is suitable for use with NEMA 12 enclosure types. Optional NEMA 4/4X handles are also available. All rotary handle mecha-nisms include a handle “Lock Off,” to prevent turning the breaker ON while in the OFF position. All Rotary handles indicate ON/OFF/Tripped/Reset positions, however, Universal Rotary has the added feature of inter-national markings for ON (I) and OFF (O). Cutler-Hammer Universal Rotary is made of molded material and is available in black or yellow/red.

Direct (Close-Coupled)Handle Mechanism

Direct Handle Mechanism

Direct (Close-Coupled) Handle Mecha-nisms mount directly to the circuit breaker. They are used in shallow enclosures where the standard vari-able depth through-the-door type mechanism is not practical or cannot be used. They are typically for applica-tions where high volume, standardized enclosures are being fabricated.

The Universal Direct handle mechanism comes with a door interlock to prevent opening the enclosure while the circuit breaker is in the ON position. It is also available without a door interlock.

The Universal Direct handle mechanism is UL 489 listed, IEC 60947-1/2 and meets CSA requirements.

Special CalibrationSpecial non-UL listed calibrations are available for certain ambient tempera-tures other than 40ºC and for frequen-cies other than 50/60 Hz or dc. Reduced interrupting ratings will apply for 400 Hz applications.

50ºC CalibrationAdd suffix “V” to Catalog Number for complete breaker when ordering listed ampere ratings for breakers to be used in 50ºC ambients. Contact Eaton Electrical for availability.

Moisture-Fungus TreatmentAll Cutler-Hammer 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. Order by description.

Time-Current Curves

Tripping CharacteristicsThe operating values specified for the inverse time overcurrent releases (thermal overload releases, “a” releases) are mean values of the scatter bands of all setting ranges from the cold state and with uniform current loading of the conducting paths.

The tripping characteristics of the instantaneous (electromagnetic) short circuit releases (“n” releases) are based on the rated phase current In which, in the case of circuit breakers with adjust-able thermal overload releases, is also the upper value of the setting range. With a lower setting current, a corre-spondingly higher multiple is obtained for the operating current of the “n” release.
