Contact Pants
● Imported 0.5t silicon steel plate was used for the core to improve mechanical durability.
● MAG mold was used for lamination to increase the bond strength, and the extra-low
noise at the world’s best level was achieved by processing with a plane view of 3/100
accuracy. (≤40dB)
● Improved coil attractive force prevents noise in holding, and the power consumption was
minimized.
Improved Switching Lifetime / Noise Reduction
● Eco-friendly Sn contact was used.
● Arc-resistance, wear-resistance and electrical lifetime were improved to be suitable to
inching, plugging, etc. for heavy load facilities. (2.5 times longer in electrical lifetime
specification)
● Knurled auxiliary contact improves contact reliability.
● There is no disconnection, contact fault or operation fault, due to the coil terminal
separation preventive structure.
High Reliability
● a contact and b contact are marked respectively so that erroneous wiring is prevented.
● AC operation and DC excitation were applied for smooth operation even in case of severe voltage
drop.
● A magnetic circuit reduces the power consumption at a level of half that of other companies
● This product has a noise filter for optimal use in noisy places.
● There is no vibration in outdoor use, e.g. in a humid boiler room.
Operation in Voltage Fluctuation / No Noise for VMC-50 or Higher

Applied Standard and Ratings
● Thermoplastic nylon material prevents breakage basically.
● There is no deformation or breakage in connecting process due to the
reinforced rib.
Prevention of Breakage
● Both screw mounting and DIN standard 35mm rail mounting are available.
● The compatibility with other companies products facilitates interchangeable
replacement and maintenance, in forming a new panel board or in maintaining an
existing board.
● This product is compatible with domestic and overseas products in mounting.
Diversified Mounting Types
● High stability is ensured by providing finger-proof safety covers,
conforming to standards including, IEC and UL.
High Stability
● The head of screw is large enough to endure connecting torque.
● Tap fault was basically improved by hi-roll tap processing.

Note) 1. Name refers to the symbols used in ordering.2. The name for 220V 60Hz is AC 220V, the name for 380V 50Hz is AC 440V, the name for 220V 50Hz is AC 240V, and the name for 415V 50Hz is AC 480V.3. The operation is ensured at 40°C of ambient temperature and in a range of 85~110% of rated working voltage of coil.4. If the voltage of operating circuit goes beyond the rated working voltage of the coil, the insulation of coil is accelerated and mechanical switching durability is reduced.5. ※-marked coil is special ratings that require previous contact before you order.

■Application to Y-Δ Starting·There are two Y-Δ staring methods, using 3 magnetic contactors and 2 magnetic contactors, and unlike the contactors
for Y (MCS or MCS1) and Δ (MCD), an electric interlock must be installed.
·3-magnetic contactor type is generally applied, and it can prevent insulating breakdown by leakage current becausevoltage is not applied to the motor windings during the stoppage of the motor.
·2-magnetic contactor type is economical, but it is not suitable for devices with long-pause such as fire extinguisherbecause voltage is applied to the motor windings even during the stoppage of the motor.
·Refer to the table below for the comparison of diversified current values of direct starting and Y-Δ starting

■Application to Special Environment
High temperatureWhen magnetic switches or magnetic contactors are operated at a high ambient temperature, the temperature mainlyinfluences the insulation lifetime (continuous conducting lifetime) of the operating coil and aging of the molded product.
Low temperatureMagnetic switches and magnetic contactors may be operated in an extreme condition such as in a cold area or refrigerator.In that case, refer to the storage temperature and operating temperature.
DustMagnetic switches and magnetic contactors used in the casting plant, construction site and fine article conveyance system isexposed relatively large quantity of dusts, where a dust-proof control board is required.
Tropic areaExport through the tropic area is greatly influenced by humidity. Absorbents are placed in the export package to preventhumidity, the greatest cause of mold and rust.
Corrosive gasCorrosive gas existing in the atmosphere where magnetic switches and magnetic contactors are operated are SO2, H2S,Cl2, NH3, etc. Conducting parts are strong against these gases and protected by plating, but there is no way to givecorrosion-resistance to contacts, which may lead to temperature rise by increased contact resistance.In addition, the corrosion by these corrosive gases may be slowed down in the dry place, so that the control board can bedried as a basic countermeasure.
■Performance
The performance stated in this catalog is the result of the testing under the conditions specified in the standard IEC 60947,AC magnetic switch. Please note that these specified conditions may differ from actual operating conditions.
■Operating Condition
1) Ambient TemperatureInsulation may be deteriorated and damaged even in the normal operating conditions. The insulation lifetime becomes shortespecially at high ambient temperature. The insulation lifetime is reduced by half when the ambient temperature increases by6~10℃. High ambient temperature and continuously applied voltage which is higher than rated voltage lead to high coiltemperature, and thereby extremely short lifetime.
2) Vibration and ShockOperating errors of contacts do not occur at 2G vibration and 5G shock, but even under these levels, continuous vibrationand shock may cause fatigue damage and operating fault. Especially, pay attention to the resonance in the control boardbecause it may cause high vibration to the product.
3) ContactIf the contact by overcurrent switching or deterioration of contact due to abnormal wear is welded and not opened, a greatdanger occurs to the device. Secure safety when closing or opening is impossible due to mechanical restraint or contactweld. Replace the magnetic switch or magnetic contactor and contact our after-sales service center.

Thermal Overload Relay
● Thermal load relay protects a motor against burnout by overload, constraint and open phase operation.
■Direct Connection with the Magnetic Contactor
■Easy Operation
The thermal overload relay can be connected with a magneticcontactor directly in series without any connector.(Applied model: STH-22, 40, 85)
Current SettingUse a “+”or “-“ driver to set rated current corresponding to the motor load.Manual-automatic reset setting
Manual-Automatic Reset SettingFor the user’s convenience, manual reset or automatic reset is set by the user.
Manual ResetTurn the reset bar until the arrow indicates “H”and the bar is projected, as shown in the left figure.
Automatic ResetPush the reset bar and turn the bar until the arrow indicates “A”.
Manual Inspection by External TripFor the user’s convenience, manual trip is available externally, and overcurrent is easily identified by the projection in case of trip.
