Trip Units
The breakers are availble as a complete entity or in kit
form where a Breaker Frame and an interchangaeble trip
unit are the basic components. The interchangeability
feature covers the electromechanical trip units described
here and the electronic devices described on page B12.
Each Trip Unit is equipped with an Interchange Interlock
that prevents the inadvertent use of a trip unit designed
for the FE250 model in an FE160 or vice versa.
The standard Electromechanical Trip Units are equipped
with a GE patented fault type indicator. The device has

The following versions are available:
LTM (line thermal magnetic protection)
(FE...TA sub type)
A trip unit designed for the protection of generic loads, the
device is available as 3 and 4p model for the FE160 and FE
250 frame sizes.
This sub type has an adjustable thermal and magnetic
setting. The thermal setting range is 0.8 to 1 x In and the
magnetic relay is adjustable from 5-10 x In. (Fixed at 8 x In
for Ratings < 80A).
LTMD (Selective thermal magnetic protection)
(FE...TD sub type)
A trip unit designed for the selective protection of generic
loads, it is available as 3 and 4p model for the FE160 and
FE250 N, H & L breaker types.
Making full use of the FE frames unique propeties this
device offers both full and enhanced selectivity with
downstream devices as the Record Plus FD160, the
ElfaPlus, Red Line MCB's and the Surion Motor Starter.
This sub type has an adjustable thermal and magnetic
setting. The thermal setting range is 0.8 to 1 x In and the
magnetic relay is adjustable from 5-10 x In.
B
C
D
GTM (generator thermal magnetic)
(FE...TG sub type)
Suitable for the protection of generator circuits and or long
cable runs, the device is available as 3 and 4p model for
the Standard (FE160N & FE250N) and Hi-Break (FE160H &
FE250H) breaker types.
This sub type has an adjustable thermal and magnetic
setting. The thermal setting range is 0.8 to 1 x In and the
magnetic relay is adjustable from 3-5 x In.
E
F
G
Mag Break™ (magnetic only)
(FE...MO sub type)
A trip unit designed to offer short circuit protection for, use
in motor protection circuits in coordination with a
contactor and thermal overload relay in accordance with
the EN 60 947-4 standard. The device is available as 3 and
4p model for the FE160 & FE250 N, H & L breaker types
This sub type has NO thermal protection and an magnetic
relay that is adjustable from 10 to 15 x In.

Y (non automatic - switch disconnector)
A 'dummy 'trip unit available in a 160A and 250A variant.
Has no protection elements.
Designed as switch disconnector.

two indicator flags, one indicating an overload event
(coloured brown) and a second, coured blue, indicating
a short circuit or an event triggered by an RCD .
(If the indicated protection devices are present).
Thermal protection devices are normally calibrated at an
ambient temperature of 40 degrees centigrade. Some
executions are also available in a verison calibrated at 55
degrees. The time current curves published here are valid
for both executions.
