General
Electronic motor protection relay TI 180 E is a
compact unit with integrated current transform-
ers for motor current measurement.
With TI 180 E a motor can be protected
against:
- thermal overload
- overcurrent (indication by flashing)
- single-phasing and asymmetry
- overtemperature
(thermistor measurement)
Checks
Supply voltage U
s
and frequency must be
identical to that shown on the upper side of the
unit.
Rated motor operating current I
e
must be within
the current range of the relay, 20-180 A (which
can be adjusted down to 2.5-5 A, as described
under “Connection”).
Installation
TI 180 E is designed for wall mounting using
four M5 screws (fig. 1) or on standard rail EN
50022-35

For dimensions, see fig. 15.
Connection, contactor and electronic
motor protection relay
- conductor bars 037H3027 and three M6
screws onto Danfoss contactor CI 105,
or
- conductor bars 037H3028 and three M6
screws onto Danfoss contactor CI 141/170 EI
(fig. 2A).
Without conductor bars:
Connection to contactor and motor can be
made easier by looping the cable as required
before installing the unit.
TI 180 E as secondary relay
As secondary relay, TI 180 E can also protect
motors with full-load currents if more than 180
A and high-voltage motors for operating
voltages of more than 1000 V.
Recommended current transformer data:
Min. operating voltage =
rated operating voltage of motor
Min. primary current =
operating current of motor
Class and overcurrent factor: 5 P 10

Finger protection of main terminals
Use finger protection 037H3246 for TI 180 E/
CI 105 and 037H3409 for TI 180 E/CI 141/CI
170 EI (fig. 2B).
Control connections (fig. 7, A-D)

B:98-97, 96-95: Output contact
C: 3-off (r1,r2,r3) For remote reset module RRM.
Connection (option) shown in
diagram on RRM (fig. 11).
D: 1T1, 2T2 :
Thermistor connection
(overtemperature protection).
If this function is used, first
remove the factory-mounted
resistor RT (1 kohm) and then
connect the PTC temperature
sensors built into the motor to
terminals 1T1 and 2T2.
