Versions are available as Ground Fault Circuit Interrupters and as Ground Fault Equipment Protectors. The -MC product line consists of Thermal Magnetic Circuit Breakers and Ground Fault Sensing Breakers that are designed, manufactured, and certified to North American standards, UL, UL, UL, and the equivalent CSA standards, CSA. No..,. No.. Bul. -MC Thermal Magnetic s are generalpurpose 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. Application Information Selection of a Bul. -MC circuit breaker with appropriate circuit protection includes consideration of: Circuit voltage Circuit frequency Available short circuit current Continuous current rating Application considerations Special operating conditions The following discussion is based upon National Electric Code and UL requirements. Similar considerations are appropriate for Canadian applications. Circuit Voltage Bul. -MC circuit breakers are rated by voltage class. Applications should not exceed the listed voltage range (see Table ). Standards Compliance for GFEP ( ma trip sensitivity) UL CSA C. No. Circuit Frequency Bul. -MC circuit breakers may be applied to frequencies from DC up to Hz without derating. For applications above Hz, contact Rockwell Automation with specific application information for the derating of the circuit breakers. Available Short Circuit Current Bul. -MC circuit breakers should only be applied in those applications in which the available short-circuit (or fault) current is less than or equal to the interrupting rating shown in the Voltage and Interrupting Ratings table.

Consult your local Rockwell Automation sales office or Allen-Bradley distributor for specific rating. - Publication A-CAA-EN-P

3 Continuous Current Rating Bul. -MC circuit breakers are rated in RMS amperes at a C ( F) ambient temperature per UL (CSA. No..). 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 C ( F) ambient, then the circuit breaker should be derated. Contact your local Rockwell Automation sales office or Allen-Bradley distributor for derating information. The characteristic trip curves are shown on pages - -. 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 C ( F), a circuit breaker will open ("clear the circuit") automatically at some total time that will be within the "Minimum" and "Maximum" time shown as the "Minimum" and "Maximum" curves. For example, page - shows that a one pole, A, -MC trips in not less than s and not more than s on a 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. Standard current ratings are,,,,,,,,,,,,,,, and A. Application Considerations 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. Bulletin -MC circuit breakders are "non-% rated" as defined by UL Part... As such the circuit breaker's rating should be loaded to no more than %, if used with continuous loads. Bulletin -MC Product Description Branch Circuits: Bulletin -MC 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. For example: ) Motor Branch Circuit Bulletin -MC circuit breakers are not horsepower rated because they are able to safely interrupt currents far in excess of the locked rotor value for a selected motor. This ability is recognized in the codes and standards and is also established by the UL and CSA tests described in UL and CSA C. No.. standards. The size of a Bulletin -MC circuit breaker should be determined following the guidelines for an Inverse Time. References: NEC. and UL A. Also see CEC and appropriate Canadian Standards. ) Transformer Protection Bulletin -MC circuit breakers may be used for transformer protection following the guidelines established. References: NEC and UL A. Also see CEC and appropriate Canadian Standards. ) Heater Load, Lighting, and Other Load Protection Bulletin -MC circuit breakers may be used for protection of heater loads, lighting loads, and other loads following the guidelines established. References: NEC Article and UL A. Also see CEC and appropriate Canadian Standards. 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.. Also see CEC. Publication A-CAA-EN-P -

Versions are available as Ground Fault Circuit Interrupters and as Ground Fault Equipment Protectors. When protection from low-level fault currents for North American standards is required, two versions of protection are available. s with protection for personnel use a threshold of ma sensing to provide protection for people. These are typically know as Ground Fault Circuit Interrupters or GFCIs. s that provide protection for equipment at a sensing threshold of ma are also available. These are typically known as Ground Fault Equipment Protectors or GFEPs. The following devices are tested and listed to meet the North American standards of UL, UL (for GFCI), UL (for GFEP), and CSA.
