Switching Circuit Protection
Connect the SVC at a position nearer to the equipment than the overcurrent protection device (fuse, MCCB) as is shown in the diagram. When the SVC is shorted, the overcurrent protection device operates (trips or blow off the fuse). If the overcurrent protection device can not be installed in position, connect a fuse at 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.
When operated at location near heating element or exposed to direct sun light, confirm that the ambient temparature range. 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.

Telecommunication Circuit Protection
Pay due attention to the surge energy generated by the load. Select SVC referring to the pulse lifetime rating. 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.
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

Typical values measured at a test frequency of 1kHz
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.
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.
DISC Ceramic Capacitors
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.
Maximum continuous sinusoidal RMS voltage at 50/60Hz which may be applied.
Maximum continuous DC voltage which may be applied.
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.
Maximum average power that can be applied within the specified ambient temperature.
