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 .

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 .
