A global source for
innovative electrical power distribution solutions
Expanded capabilities … in less space
The advanced arc running system enables
Magnum to control the arc direction, while
also providing for higher interrupting
capacity in a smaller space.
Increased ratings in less space provide the
flexibility to design more robust electrical distribution
systems capable of handling larger available fault
currents, and providing better coordination with
downstream devices. Magnum breakers are designed
for use in low voltage assemblies: switchgear,
switchboards, motor control centres, and transfer
switch equipment.
Safety first
Much consideration was given to
operator safety and system security.
•
Improved C-loop current path
design provides dramatic enhance-
ments in both safety and efficiency.
•
Higher current ratings increase the blow-on forces
on the contact surfaces, allowing the proper
downstream protective device to open, isolating the
fault and increasing uptime.
•
Positive On is indicated on the breaker faceplate.
This unique interlocking feature prevents the
levering door from being opened if the contacts are
welded, protecting personnel from exposure to live
primary contacts. Making current release prevents
the breaker from closing in on a fault with peak
current exceeding 25 times the RMS nominal current.
•
Keyed sensor plugs ensure error-free installation of
the sensor in the field.
•
Deadfront faceplate isolates the operator from the
primary voltage when the breaker is energized.
•
Anti-pump prevents any attempts to reclose the
breaker on a short circuit fault if the close signal
(
mechanical or electrical) is maintained.
Proven performance …
time and again
For over 70 years, Eaton has
