Voltage drops should be reviewed when

Power loss should be reviewed when
V-EAs with high rated currents are used
(e.g., enclosure heating).
The listed V-EA internal resistance
values should not be used in
calculations of available short-circuit
current downstream of the V-EA. The
dynamic impedance of the V-EA under
short-circuit conditions can vary
significantly from internal resistance
values in normal operation.
Mag. Trip Current = 1.1 x curve current
Mag. Trip Current = 1.2 x curve current
Mag. Trip Current = 1.4 x curve current
Mag. Trip Current = 1.5 x curve current
For example, at 16 2/3 - 60 Hz the magnetic trip zone for
the “G” characteristic is 8 to 10 times the rated current of
the specific V-EA (i.e., hold for at least 100ms at 8 x RC,
trip in less than 100ms at 10 x RC). With a 400Hz current,
a magnetic trip at 10 x RC would be greatly delayed
(thermal would likely trip first), as the magnetic trip zone is
now 11.2 to 14 x RC. If a quicker magnetic trip is required
with 400Hz, the “B” or “C” characteristic should be
considered.

Resistances listed are “hot” values, as
opposed to cold start values. Operating
voltage drop across the V-EA and power
loss per pole can be approximated with
basic formulas:
The thermal trip is not affected by the frequency of the line
current. The magnetic trip is within the trip zone of the
characteristic curve for frequencies from 16 2/3 to 60Hz. At
lower and higher frequencies, the magnetic trip will be
delayed longer than indicated by the characteristic curve,

MA- Series
Three Phase Adjustable Trip
Miniature Circuit Breakers/
Manual Motor Controllers
The MA was designed to handle the high
inrush loads of 3 phase transformers,
power supplies, motors, etc. The MA
protects wiring and equipment from
damage caused by the three major
classes of over-current, yet greatly reduces the number of nuisance trips in high
starting and inrush current circuits.
An IEC device with excellent ratings under
a UL listing at 480Y/277V (including group
ratings) and at 500V under international
standards, the Altech/ABL Sursum MA
provides short and long term cost effective
circuit protection for USA and/or export
applications. The short term advantages
include: (1) adjustable thermal trip allows
finalization of initial designs before
procurement of the load equipment is
complete; (2) snap-on mounting for readily
available, internationally standardized DIN
Rail saves panel layout design time as well
as installation and change labor; (3) large
cage-clamp terminals with screws suitable
to power screwdrivers, simplifies and
speeds wiring; (4) convenient switched
disconnect during factory testing and/or
initial start-up saves time and aggravation.
The key long term advantage is customer
satisfaction and proven over-current protection of wiring and equipment (and the
lack of rework/repair costs).
