4 Introduction CI 5- minicontactors cover the power range up to 5.5 kw and are available for C 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 and dditionally 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.

6 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 Or der ing Motor starter Range Max. fuse HRC 2) Y/Dstarter gl, gl, gg BS 88, type T Form II Code no. type 1 type 2 type 1 type H H H H H H H H H H H H3141 TI 9C-5 To IEC coordination types 1 and 2: Coordination type 1: ny 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. fter 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 US. 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: 12 - With direct start the suitable motor starter range is , i.e. thermal overload relay 047H With Y/D start, the suitable motor starter range is 10 16, i.e. thermal overload relay 047H IC.PD.C10.F B4167 Danfoss /S, C-SMC, mr,

9 Tripping graph TI 9C-5 3-phase overload Measure overload current 2) Find the overload factor (x) by dividing the measured value by the set value of the thermal overload relay (motor full load current). 3) Find (x) on the horizontal axis and follow a line vertically up until it intersects the upper curve. 4) From the intersection point, follow a horizontal line to the left and read off on the vertical axis the time that will elapse before the thermal overload relay cuts out the motor. Explanation of graphs Mean value curves Upper curve: 3-phase tripping and asymmetric load tripping at min. setting. Lower curve: symmetric 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. 3-phase tripping: x = symmetric load tripping: x = measured current rated motor current measured current max. scale value on overload relay Tripping time 2 < T p 10 s at 7.2 x I e class 10 Note! In general, the thermal overload relay is always set on motor full load current. symmetric load tripping Measure the current the motor draws from one of the intact phases. 2) Find the overload factor (x) by dividing the measured value by the maximum scale value of the thermal overload relay. 3) Find (x) on the horizontal axis and follow a line vertically up until it intersects the lower curve. 4) From the intersection point, follow a horizontal line to the left and read off on the vertical axis the time that will elapse before the thermal overload relay switch off the motor.
