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 uctuations.

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 oer high exibility.

One of the most important features is status feedback provided by mechanically linked and mirror contact performance in conrmity 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 dierential mechanism for sensitivity to phaseloss conditions.

Features • Compact design

• High exibility

• Power range up to 5.5 kw

• For ac and dc coil voltages

Thermal overload relay TI 9C-5

Ordering

Introduction

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

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.

) 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:

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

- With direct start range for motor starter is used

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

Example: Full load current: 12A

- With direct start the suitable motor starter range is 8.0 – 12A, i.e. thermal overload relay 047H3141

- With Y/D – start, the suitable motor starter range is 10 – 16A, i.e. thermal overload relay 047H3140

Explanation of graphs

Mean value curves Upper curve: 3-phase tripping and asymmetric load

tripping at min. setting. Lower curve: Asymmetric load tripping at max. setting.

When tripping from the operationally warm condition, the tripping times are approx. 30% of the values shown. These values apply at an ambient temperature = 20 °C.
