Product technial information：

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 

e 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 the

time to trip due to thermal action and reflect overload

protection of the wire and connect load. The higher current

portion of the curves (lower right) depicts the trip due to

magnetic action of the circuit breaker and reflects protection

due to short circuit level currents.
