CI-TI™ Contactors and Motor Starters

Type CI 6 - 50

CI-TI™ contactors and motor starters
provide trouble-free switching and
maximum protection for costly motors
and other electrical equipment.

The components are compact, easy to
install and extremely reliable.

They are designed to meet demanding
requirements, based on comprehensive
application experience.

More than sixty years of manufacturing
experience ensure that our contactors
and motor starters stand out with regards
to quality and long life.

Contactors CI 6 – CI 50 for
AC coil voltage (no built-in
auxiliary contacts)

Danfoss contactors CI 6 – CI 50 cover the power
range 2.2 – 25 kW.
CI 6 is built up as a combined contactor/control
relay.
CI 9 DC – CI 30 DC and CI 9 EI – CI 30 EI are
contactors for DC coil voltage within the power
range 2.2 – 15 kW. The range CI 9 EI – CI 30 EI has
built-in interface relay for PLC application with
24 V DC output.
Accessories include a wide selection of clip-on
auxiliary contact blocks and timers, interface
modules and RC links.
The CI 6 – CI 50 range also includes thermal
overload relays for protection of squirrel-cage
motors.

Thermal overload relays
TI 16C, TI 25C, TI 30C for
contactors CI 6 – CI 30

Thermal overload relays TI 16C, TI 25C and
TI 30C are used with contactors CI 6 – CI 30 to give
protection of squirrel-cage motors of 0.09 kW to
15 kW.
The relays have single-phase protection, i.e.
accelerated release if phase drop-out occurs.
This is particularly important for motors with
delta-connected windings.

Other features of TI 16C / 25C / 30C:

• stop/reset button

• manual/automatic reset

• test button

• double scale for direct start or Y/D start

• galvanically isolated signal contact

Selection of thermal overload relay

The selection of a thermal overload relay must
be based on the motor full load current and the
method of starting:

- With direct start the range for motor starter is

used.

- With star-delta start the range for Y/D starter is

used.

Example:

Full load current: 16 A

- With direct start, the suitable motor starter
range is 11 – 16 A, i.e. thermal overload relay

047H0212.

- With star-delta start, the suitable Y/D starter
range is 10 – 16 A, i.e. thermal overload relay
047H0210.

The range 13 – 20.8 A could also be used, but

thermal overload relay 047H0211 will not
release as quickly if one phase drops out.
