17 HYUNDI USeries ccessories Mechanical interlock unit l UTL Mechanical latching block l ULB Mechanical interlock unit provides reliable interlocking between two contactors for reverse operation. Handling Mechanical interlock unit must be installed on contactors directly without side mounting auxiliary contact block. If side mounting auxiliary contact blocks are installed on contactors, the inner side blocks must be removed. When side mounting auxiliary contact block is required, two blocks can be installed on both outer sides of contactors. Mechanical interlock unit must be installed vertically. Electrical interlock should be applied via NC contacts of UTL for UMC contactor or side mounting auxiliary contact blocks (UL) for UMC00. Simultaneous closing by excessive force may cause damage. Plastic Steel Mechanical latching block keeps the contactor and control relay mechanically latched in the event of instant control power out or voltage drop, so they can keep ON status. Mechanical latching block starts to latch the contactor or control relay when it is energized, and keep latching during the dropout of contactor or control relay. The mechanical latching can be released electrically or manually. Handling How to OFF Electrical: Put power to the mechanical latching block. Manual: Push up the lever to O position. How to ON Electrical: Put the control power to contactor or control relay. Manual: Push down the bridge at I until mechanically latched. Caution Mechanical latching block must not receive control power for more than sec. It is not allowed to put the control power on contactor (or control relay) and mechanical latching block at the same time.

Usually, lighting load switching frequency is smaller than the other applications, so electrical lifetime would not be the major parameter to select the contactor. Incandescent lamp The contactor for incandescent lamps can be selected according to C utilization category considering the inrush current at hot condition. The resistance of the incandescent lamp filament is small at cold condition, so the inrush current can be of the rated current instantaneously. However, the inrush current at hot condition is limited to of rated current by circuit impedance and selfheating.

28 HYUNDI USeries Technical Information Thermal Overload Relay Tripping function Main terminal (Line) name Current setting knob Test button Test button is for test operation mainly. When the test button is pushed down, the NC contact opens; whereas, there is no change on NO contact. If the test button is pulled up, the status of the thermal overload relay becomes trip status; trip indicator comes up, NC contact opens, and NO contact closes. Test button can be also used for emergency stop. Phase loss protection Differential tripping mechanism Differential tripping mechanism makes trip faster in the case of single phase loss than all three phase overloaded condition. s shown in the figure, when R phase is loss, the bimetal of R phase remains, so it fixes up the lower slide. t the same time, the other bimetals of S phase & T phase are bent, so they move the upper slide. The trip lever move to hit the trip mechanism according to the different moving ratio of lower slide and upper slide. Therefore, in the event of R phase loss, the tripping time is shorter than all three phase overloaded condition, L/L/L: phase line (R, S, T) ///: ux. contact Normal position (Untripped position) ll three phase overloaded condition (Normal tripping function) Trip indicator and this is the same for S phase and T phase. Thernal overload relay selection Single phase loss (Differential tripping) (R phase fixed) Three steps of the setting current can be adjusted by "" or "" driver. Setting current cover Unintended change of setting current or reset method can be prevented by setting current cover. Setting current cover can be sealed, so only authorized personnel can adjust the setting current and reset method. Main terminal (Load) uxiliary contact Main terminal Excessive force on operation buttons can cause malfunction or damage. Trip indicator comes up in the event of trip, so the thermal overload relay status can be visually checked. The trip indicator should not be returned by force. Reset button position: utomatic reset Thermal overload relay resets automatically around one minute after tripping. H position: Manual reset This is factory setting value. Tripped thermal overload relay can be reset manually by pushing down the reset button. Manual reset shall be done at least one minute after tripping. Short starting time motors For motors of normal starting time within a few seconds, the relays can be selected by the table of page. The full load curent (FLC) of the motor must be within the setting range of the themal overload relay. The starting time of highinertia motor is an important factor at the selection of thermal overload relays. The tripping time of the motors, whose starting current is of the rated current, can be obtained from the UTH tripping curves, page. This time should be longer than around % of the motor starting time. Long starting time motors If the starting time of the motor is longer than the tripping time of UTH, the current transformer type can be used. The current transformer type relays include the NonTripping features during the motor starting time. The rated current can be decreased by looping the primary cable several on the transformer according to the following table. Current configuration ratio according to loop turns (Example ) Primary loop turns Current range () Current ratio / /././ /./././ The second rated current of current transformer is, the overload relay is able to control the current between and. The corresponding setting value for the relay can be calculated by using the following formula.
