Sizes, dimensions, weights and
configurations
Magnum circuit breakers are available in four physi-
cal frame sizes, all centered around a modular design
approach. The versatile Magnum design concept maxi-
mizes enclosure density with the same basic height and
depth, differing only in width.

please refer to Section 8: 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 – 5000 Amps): Decreased
footprint when space is at a premium.
•
Double standard frame (4000 – 6000 Amps): 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.
