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								Thermal overload relays TI 16C, TI 25C and

1)		To IEC 947-4 coordination types 1 and 2:
		Coordination type 1:		Any type of damage to the motor starter is permissible. If the motor starter is in an enclosure, no external
				damage to the enclosure is permissible. After a short-circuit the thermal overload relay shall be partially or
				wholly replaced.
		Coordination type 2:		No damage to the motor starter is permissible, but slight contact burning and welding is permissible.
2)		In accordance with HRC form II, TI 16C, TI 25C and TI 30C are suitable for operation in Canada and the USA.
3)		50 A in Norway.

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.
