MAGNUM PRODUCT GUIDE CA013002EN—April 2017 www.eaton.com 9
Family features and characteristics
Universal family features
As mentioned, Magnum low voltage power circuit breakers
consist of four product families. Although each family has
its own unique performance and features, each Magnum
breaker boasts a wide array of common design elements.
These common design elements deliver proven performance
with expanded capabilities, no matter which product family is
applied. To fulfill the latest market needs with proven reliability
and performance, Magnum is the clear choice for low voltage
applications.
High performance interruption &
withstand levels
Magnum provides Magnum provides large range withstand
and interrupting ratings to maximize selectivity and system
coordination.
•
A range from 42kA up to 200 kA interrupting - application on
power distribution systems with higher available fault currents.
•
Up to 130 kA withstand (short-time) - total selectivity/selective
coordination/discrimination between main, feeder, and branch
circuit breakers.
•
Current limiting performance - lower let-through currents for
superior equipment protection.
•
Optional Arc Flash Reduction Maintenance System
(ARMS™) - reduces arc flash hazards and improves operator
and maintenance safety.
•
Circuit breakers performance tested - meet or exceed all
applicable ANSI, NEMA, UL, CSA, IEC, EC and IEEE standards.
Specifically, the circuit breakers meet or exceed the following:
UL 1066, ANSI C37.13, ANSI C37.16, ANSI C37.17, ANSI C37.50,
IEC 60947-2, GB14048.2-2008, and CSA TIL No. D-34.
Continuous current ratings
•
800 to 5000A (UL1066), 800 to 6300A (IEC) - ensuring
maximum uptime over expansive frame rating range.
•
100% rated – designed for continuous operation at 100% of
current rating.
•
Reverse feed capable - top or bottom feed for multiple source
applications.
Sizes, dimensions, weights and
configurations
Magnum circuit breakers are available in four physical frame
sizes, all centered around a modular design approach. The
versatile Magnum design concept maximizes enclosure density
with the same basic height and depth, differing only in width.
ote:N For detailed Magnum breaker outline drawings, please refer to
Section 11: Magnum drawings and outlines
•
Narrow frame (800 – 2000 Amps): Promoting the most
compact modular enclosures.
•
Standard frame (800 – 3200 Amps): Ideally suited for vertically
stacked modular construction.
•
Double narrow frame (4000 Amps): Decreased footprint when
space is at a premium.
•
Double standard frame (3200 – 5000A): Ideal for main and
tie applications.
Increased ratings in less space provide the flexibility to design
more robust electrical distribution systems, capable of handling
larger available fault currents while providing better coordination
with downstream devices.
