High withstand ratings
Magnum provides high interruption and withstand
ratings in a small physical size.
Through-the-door design
All controls, indicators, and the trip unit are visible and
can be safely accessed without opening the
compartment door.
Common height and depth
All three Magnum frame sizes have the same identical
height and depth to facilitate standardised designs in
low voltage assemblies.
Complete trip unit family
A full range of Digitrip® programmable and electronic
trip units has been expanded to offer customers a
choice of protection, information, and communication
capabilities to meet specific requirements.
Eaton’s innovations meet the needs of today’s modern
air circuit breakers:
•
The capability to design more flexible systems that
can withstand larger available fault currents.
•
Better coordination with downstream devices.
•
Reduced size of the switchgear assembly.
•
Integrally designed breaker levering mechanism and
cassette for drawout breaker with clear indication of
connect, test, and disconnect positions.
Meeting the challenge
Magnum breakers are engineered specifically for use in
low voltage assemblies applied at nominal voltages of
380, 415, 440, 500
and 690 Vac. Ten continuous ratings
– 800
A through 6300 A – are covered with three frame
sizes. Drawout and fixed mounting units are available
in 3 or 4 pole designs.
Controls and indicators are conveniently grouped on
the breaker’s front escutcheon where they can be
easily viewed and accessed through a cutout door.
