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.

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.

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.
