9 MCCB ELCB Circuit Protector DC Contactor Relay Graph for Electrical Endurance(TMC9 ~ 85) 3Ø AC200~220V 3Ø 80~440V for Star-Delta Starting There are two different methods of Star-delta starting of a motor; one using three magnetic contactor and the other using two. Between the contactor for the Star circuit (MCS or MCS1) and that for the delta circuit (MCD), it is indispensable to establish electrical interlock between the two contactor. The three contactor method is generally preferred, since no voltage is applied to the motor winding while the motor is not running and thus destruction of insulation by leakage current can be suppressed. The two contactor method is economical, but voltage is applied to the motor winding while the motor is not running, and thus it is not suitable for application such as fire fighting equipment whose downtime is very long., Voltage and Torque of the for Star-Delta Starting Starting For Starting (Star ) For Operation (Delta ) Method Torque Full Contact Voltage Full Contact Voltage Contact Voltage Direct 6lm 1.5T 6lm Em lm lm Em Star-Delta 2lm 0.5T 2lm Em lm lm Em Im: load current to the motor of delta wiring, Em : line-to-line voltage, T : rated torque (Change in torque is an estimated value.)

Therefore, the selection points are, 1 The total of the input current to the loads should not exceed the rated current of the magnetic contactor. 2 Inrush current by starting should remain below the open circuit current capacity of the magnetic contactor. Incandescent Lamps Because the filament of an incandescent lamp is low especially at ambient temperature, theoretically the inrush current at the moment of lighting the lamp is 3 to16 times of the rated current, but the impedance of the circuit and the self-heating of the lamp limit the inrush current to 7 to 10times of the rated current in practical conditions. The example of characteristics from the moment of lighting the lamp to the point being stable current is shown in the graph in the right. The magnetic contactor applied for incandescent lamps should be selected with a transient current of this level taken into consideration, and the rated current to the incandescent lamps should be the same as or lower than the rated current.

The starter method turns on the lamp by use of a manual switch or an automatic switch such as a glow lamp, widely used for households. On the other hand, the rapid starter method turns on the lamp immediately after the switch is turned on without the use of a mechanical contact, generally applied for buildings, factories, hospitals and schools. The starting current of a fluorescent lamp varies depending on the ballast circuit and whether or not the power factor adjustment capacitor exists in the circuit. In any case, as the starting current is about 10 times of the normal operating current, so it is recommended to select the magnetic contactor so that its capacity is the same as lower than operating current.

12 MCCB ELCB Circuit Protector DC Contactor Relay Mercury Lamps External Dimension A mercury lamp is the combination of a mercury lamp and a ballast, and the starting characteristics of a mercury lamp vary depending on the type of the ballast. The types of ballasts are the general type (low P.F. type and high P.F. type), the fixed power type and the low starting current type and the respective starting characteristics are shown in the graph in the right. For the general type and the low starting current type, a starting current of 1.2 to 1.8 times of the rated current flows through the ballast for the first few minutes. Besides, the starting current of the fixed power type is lower than the ballast. The high P.F. type is inserted in a power factor adjustment capacitor in parallel with the power source, which causes an inrush current at the moment of starting. When a magnetic contactor is used, the point of consideration is the durability of the magnetic contactor against over current. However, our magnetic contactors are capable of withstanding the over current of 1.2 to 1.8 times of the rated current for some minutes without a problem. Therefore the selection of the magnetic contactor is recommended so that the input current of the ballast is within the input current.

13 MCCB ELCB Circuit Protector DC Contactor Relay External Dimension External Dimension Mounting Dimension for Special Environments High Temperature (Coil terminal) In case magnetic circuit breakers and magnetic contactor are used at a high ambient temperature, it primarily affects the insulation life span of the control coil (continuous switch-on life span) and the time-related change of the molded products. (Main Terminal) Low Temperature TMC150 TMC180 (Aux. Terminal) If magnetic circuit breakers and magnetic contactor are used in frigid weather condition, please refer to the storage and operating temperature. Tropical Zone What affects the export products that pass the tropical zone most seriously is high humidity, which causes fungi and rust. In such a case, please make sure to insert desiccant in the packing of the export products Mounting Hole Dust As the environments of foundries, construction sites or powder transfer equipment have relatively a large amount of dust, the panel containing magnetic circuit breakers and magnetic contactor should be of a dust-proof structure. TMC220 (Coil terminal) (Main Terminal) (Aux. Terminal) Corrosive Gas Corrosive gases that can exist in the environment where magnetic circuit breakers and magnetic contactor are in use are sulfurous acid gas (SO2), hydrogen sulphide (H2S), chloride (Cl2) and ammonia (NH3). The most of the conductors have been plated and are safe from these gases, but there is no way to improve the corrosion resistance of contacts. Existence of a corrosive gas may increase the electrical resistance of the contacts, resulting in high temperature rise. At this time, low humidity helps slow down the progress of corrosion. Therefore, maintaining the air in the panel dry can be a first remedy in such an environment. Warning 25 Mounting Hole Performance The performance set forth in this catalog has been described according to the conditions stipulated in KSC 4504 AC magnetic circuit breakers. Please pay attention to the fact that your actual operating conditions may differ from those stipulated in the above mentioned specifications. Contact Configuration(TMC) Operating Condition 1)Ambient Temperature Even under normal operating conditions, deterioration of insulation and consequential burnout may occur. Especially at high ambient temperature, insulation life span becomes shorter. In general, increase of ambient temperature by 6 to 10 cuts down insulation life span to a half. If the ambient temperature is high and at the same time a high voltage exceeding the rated voltage is continuously applied to the coil, the temperature of the coil rises and its life span could be extremely shortened. 2)Vibration and Impact Up to vibration of 2G and impact of 5G, no malfunction takes place at the contact. However, even within the limitation, if vibration or impact is applied to the device ceaselessly, malfunction may occur. In particular, care should be taken to the fact that resonance in the panel where the devices are mounted could be amplified by a large extent. TMC-9~22 TMC-22S~40S TMC-32~220 3)Contact If the contact melts down caused by excessively high current or abnormal wear of the contact, the connected machinery may be exposed to a serious danger. Please secure safety if mechanical stall or melted-down contact makes it impossible to switch on or off the device. Replace the magnetic circuit breaker or the magnetic contactor and consult our service center.
