Minicontactors

CI 5-

CI 5- minicontactors cover the power range up to 5.5 kW and are available for AC and DC coil voltages enabling reliable working with extremely low and high voltage fluctuations.

Characteristic of the minicontactors is that they are compact and suitable for applications where space is at a premium. With add-on auxiliary contact blocks, timers and other additional accessories they offer high flexibility.

One of the most important features is status feedback provided by mechanically linked and mirror contact performance in confirmity with IEC 60947-4-1 and 60947-5-1.

Additionally the CI 5- ensures safety against electric shock by extra protective distance between housing surfaces and live parts.

The CI 5- programme includes dedicated bimetallic overload protection relay with a differential mechanism for sensitivity to phaseloss conditions.

Features	•	Compact design
	•	High flexibility

• Power range up to 5.5 kw

• For ac and dc coil voltages

Thermal overload relay	Introduction
TI 9C-5

Thermal overload relay TI 9C-5 is used with minicontactor CI 5- for protection of squirrel cage motors where compactness is required. The relay 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 9C-5 :

•Stop / reset button

•Manual / automatic reset

•Test button

•Double scale for direct start or Y/D start

•Galvanically isolated signal contact

	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 9C and TI 12C is suitable for operation in Canada and the USA.
	Selection of thermal overload relay:					Example:
	The selection of a thermal overload relay must be based					Full load current: 12A
	on the motor full load current and the method of					- With direct start the suitable motor starter
	starting:					range is 8.0 – 12A, i.e. thermal overload relay
	- With direct start range for motor starter is used					047H3141
	- With star – delta start the range for Y/D starter is					- With Y/D – start, the suitable motor starter
	used					range is 10 – 16A, i.e. thermal overload relay
