Voltage drops should be reviewed
when V-EAs with high internal
resistance are used (e.g., load
voltage minimums). 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.

LINE CURRENT FREQUENCY EFFECTS ON TRIP CURVES
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, roughly as follows:

At 400Hz: Mag. Trip Current = 1.4 x curve current
At DC:
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.

The MA was designed to handle the high

protects wiring and equipment from

es the number of nuisance trips in high

An IEC device with excellent ratings under
a UL listing at 480Y/277V (including group
(a)
(b) (c) (d)
ratings) and at 500V under international (a) = MA - Manual Motor Controller
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 pro-
tection of wiring and equipment (and the
lack of rework/repair costs).
