Thermal Magnetic Circuit Breakers
The Bulletin 1489-D Thermal Magnetic Circuit Breakers are general-purpose devices suitable for the majority of industrial, inverse time circuit breaker applications.
They combine thermal and magnetic trip actions and provide accurate overload and short-circuit protection for conductors and connected equipment.
Circuit Breaker Application Information
Selection of a Bulletin 1489-D circuit breaker with appropriate circuit protection includes consideration of:
The following discussion is based upon National Electric Code and UL requirements. Similar considerations are appropriate for Canadian and IEC applications.
Circuit Voltage
The Bulletin 1489-D circuit breakers are rated by voltage class. Applications should not exceed the listed voltage and current range (see Table 1).
Available Short Circuit Current
The Bulletin 1489-D 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.
Table 1. Voltage and Current Ranges
| Region | Max. Voltage | Current Range [A] | |
| EN/IEC Regions | 1-pole | 250V DC | 2...40 |
| 2-pole | 500V DC | 2...40 | |
| North America (UL 489 & CSA C22.2 No. 5) | 1-pole | 125V DC | 2...40 |
| 2-pole | 250V DC | 2...40 | |
Continuous Current Rating
Standard current ratings are: 2, 3, 4, 5, 6, 7, 8, 10, 15, 16, 20, 25, 30, 32, 35, and 40 A.
The Bulletin 1489-D circuit breakers are rated in amperes at a 40 °C (104 °F) ambient temperature per the UL 489 (CSA 22.2 No. 5) standard. This temperature is generally used as the average temperature within an industrial enclosure. If a circuit breaker is applied in a temperature that exceeds the 40 °C (104 °F) ambient, then the circuit breaker should be derated. For IEC 60 947-2 standard, the products carry an ambient rating of 30 °C. Follow standard IEC application considerations for temperature rating in different ambient temperatures.
The characteristic trip curve is shown on . The trip bands shown for each breaker represent current tripping limits for a circuit breaker and are within the limits established by UL. For a specific current at 40 °C (104 °F), 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, page The 1489-D circuit breaker can function over a wide temperature range (‑30...+60 °C). Operation in ambient temperatures below 0 °C is based on a non condensing atmosphere (no ice). Use the graph above or contact your local Rockwell Automation sales office or Allen‑Bradley distributor to determine the correction factor based upon ambient temperature. shows that a one-pole, 15 A, Bulletin 1489 circuit breaker trips in not less than 10 s and not more than 120 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) depict 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.
Application Considerations
The following is a discussion of application considerations related to North American applications. When applying product to IEC regional requirements, follow IEC practices and guidelines.
The selection of a specific ampere rating for a specific application is dependent on the type of load and duty cycle and is governed by the National Electric Code (Canadian Electric Code) and UL/CSA. In general, the codes require that overcurrent protection is at the current supply and at points where wire sizes are reduced. In addition, the codes state that conductors be protected according to their current carrying capacity. There are specific situations that require application consideration, such as motor circuit, and guidelines for the selection for transformer protection.
The Bulletin 1489-D circuit breakers are “non 100 percent rated” as defined by UL 489, para 7.1.4.2. As such, the circuit breaker's rating should be loaded to no more than 80% if used with continuous loads.
Polarity
Positive and negative connection many not be reversed.
Branch Circuits
Bulletin 1489 circuit breakers may be used to protect branch circuits. A branch circuit is the wiring portion of a system extending beyond the final overcurrent device protecting the circuit.
Guidelines established in NEC, CEC, UL, and CSA should be used to determine the specific device.
Coordinated Overcurrent Protection
Where an orderly shutdown is required to minimize the hazards to personnel and equipment, a system of coordination based upon the faulted or overloaded circuit is isolated by selective operation of only the overcurrent protective device closest to the overcurrent condition. The user should select devices that meet this requirement.
References: NEC 240.12. Also see CEC.
Determining Ratings
The tripping characteristic for Bulletin 1489-D is Type C. Type C has a magnetic trip activated at 7…15 times the rated current of the circuit breaker. The reference temperature for the thermal tripping characteristics is 40 °C (104 °F). The Type C characteristic will suit most applications.
Use the following table and graph to determine the current rating for the breaker if the ambient is significantly different than 40 °C (104 °F).

Terminals
Standard wire (cable) connection
The standard configuration of the Bulletin 1489 is with terminals suitable for connection of stranded copper wire of the wire size #18…8 AWG (1.0 … 10 mm2). Strip length for the termination is 0.5 in. (12 mm). Terminals are shipped in the open position for ease of installation.
Lock-out Attachment
A sturdy lock-out attachment may be added to a circuit breaker. This lock-out may be padlocked so that the circuit breaker is locked in the off position.
Shunt Trip
A shunt trip may be added to a circuit breaker to allow the device to be tripped from a remote source. One version is for tripping voltages of 12…110V AC (12…60V DC) and another for tripping voltages of 110…415V AC (110…230V DC).
Auxiliary Contacts
An auxiliary contact module may be added to a circuit breaker to provide pilot duty contacts to indicate the position of circuit breaker, off or on. This contact changes state when the circuit breaker is operated either manually or electrically.
Signal Contacts
A signal/auxiliary contact module may be added to a circuit breaker to provide auxiliary contact information off and on and signal contact pilot duty contacts. With signal contacts, the contacts change state only when the circuit breaker changes state from On to Off because of an electrical operation. The module contains one signal contact, form C contact (N.O. and N.C contact with common) and one auxiliary contact (N.O. and N.C contact with common).
