Application Information

Circuit Voltage

The Bulletin 1489-M circuit breakers are rated by voltage

class. Applications should not exceed the listed voltage and

current range.

Circuit Frequency

The Bulletin 1489-M circuit breakers may be applied to

frequencies of 50 Hz and 60 Hz without derating. For

applications above 60 Hz, contact Rockwell Automation with

specific application information for the derating of the circuit

breakers.

Available Short Circuit Current

The Bulletin 1489-M circuit breakers should only be applied

in those applications in which the available short-circuit (or

fault) current is less than or equal to 10 kA (US/Canada) and

15 kA (IEC).

Application Considerations

Tripping Characteristics

The trip curve characteristics are shown on the following

pages. The trip bands shown for each breaker represent

current tripping limits for a circuit breaker and are within the

limits established by UL.

The standard tripping characteristic for Bulletin 1489-M is

Type C. Type C has a magnetic trip activated at 5-10 times

the rated current of the circuit breaker. The reference

temperature for the thermal tripping characteristics is 30 °C.

The Type C characteristic will suit most applications. 

In rare occurrences when the Type C characteristic does not

fully meet the application, Type D magnetic trip

characteristic is available, allowing for transients

approximately twice as high as the standard Type C. 

For a specific current at 30 °C, a circuit breaker will open

("clear the circuit") automatically at some total time that will

be within the minimum and maximum time shown on the

curves. For example, a one-pole, 15 A, Bulletin 1489-M circuit

breaker trips in not less than 1 s and not more than 200 s on

a 30 A current. Because the UL standard defines this time

spread, users should not specify exact tripping time. The

lower current portion of the curves (upper left) depicts th
