Notes : ① The waveform of the maximum DC applied voltage is flat. When a ripple voltage as from a rectifier source is supplied make sure that the peak voltage is kept under th Vdcm An AC applied voltage(50/60Hz) form a since waveshape. When the distortion in the waveform is extensive make sure that the peak voltage is less than times the Vacm. ② Energy : Wtm Transient energy ratings are given in the Wtm column of the specifications in Joules(watt-second). The rating is the maximum allowable energy for a single impulse of 2ms square-waveform current with continuous voltage applied. Energy ratings are based on a shift of Vnom of less than ±10% of initial value. ③ Transient peak current(Itm) The peak current rating. Itm. of varistor is based on an 8/20 ㎲ test impulse waveshape.

Switching Circuit Protection
Protection of relay (Contact coil) Protection of semiconductors
① Connect the SVC at a position nearer to the equipment than the overcurrent protection device “Ⅰ” (fuse, MCCB) as is shown in the diagram. When the SVC is shorted, the overcurrent protection device “Ⅰ” operates (trips or blow off the fuse). ② If the overcurrent protection device “Ⅰ” not be installed can in Ⅰ” “ position, connect a fuse at “Ⅱ” position. Select fuse rated current for the SVC referring to the following table. SVC Applicable fuse rated current(A) 05A 05B 1 to 2 07A 07B 2 to 3 10A 10B 3 to 5 14A 14B 3 to 10 20A 20B 5 to 15

Select varistors taking a note of operating conditions peculiar to the equipment.
③ When“Z2”SVC is connected between the equipment and ground install an ELCB (Earth Leakage Circuit Breaker). If not possible, connect a fuse or thermal fuse at Ⅲ”position. “
Installation
① When operated at location near heating element or exposed to direct sun light, confirm that the ambient temparature range. ② When operated in dusty or dirty locations, or exposed to corrosive atomospheres, or where metallic powders or salt can be expected, be sure to mount within a protective enclosure.
AC/DC single-phase circuit
AC three-phase circuit
Molding
When shielding the SVC in a resin molding, take a note of the materials used and temperature, since they influence the reliability. For further information please contact SAMWHA
Telecommunication Circuit Protection
② Pay due attention to the surge energy generated by the load. ③ Select SVC referring to the pulse lifetime rating. ④ To further reduce the tendency of sparking across the contacts connect a capacitors parallel with the SVC. This will also protect the equipment from electromagnetic wave jamming.

Varistor Terminology
Varistor Voltage : Vnom
Traffic Signal Control Vending Machine
Clamping Voltage : Vc
Maximum terminal voltage (peak voltage across the varistor) measured with an applied 8/20㎲ impulse of a given peak current.
Varistor peak terminal voltage measured with a specified current applied The DC current applied is 1mA normally.

Capacitance
Typical values measured at a test frequency of 1kHz
Test current waveform
Characteristics tests for Varistors are carried out by using 8/20㎲ test impulses Data such as the maximum clamping voltage(Vc)and the transient peak current(Itm) are obtained by using this impulse current However, for the Vc characteristics of the Axial Package type a 10mA DC squarewave current is used to cary out the test.
Rated peak transient current : itm
Maximum peak current through the varistor with line voltage applied. The maximum peak current with in the varistor voltage change ratio of ±10% with the standard 8/20㎲ impulse current applied two times at 5 minute interval.
Rated transient energy : Wtm
Maximum allowable energy for a single impulse of 2ms square-wave current waveform with rated continuous voltage applied. Maximum energy rating base on a shift of Vnom of less than ±10% of initial value.

Rated RMS Voltage : Vacm
Maximum continuous sinusoidal RMS voltage at 50/60Hz which may be applied.
Rated DC Voltage : Vdcm
Maximum continuous DC voltage which may be applied.
Pulse lifetime rating
This is expressed as the maximum allowable number of impulse currents applied. 8/20 ㎲ impulse current(or 2ms square wave) is applied at prescribed interval. This curve also provides for derating current as required with repetitive pulsing.
Rated average power dissipation : Ptam
Maximum average power that can be applied within the specified ambient temperature.
