SVC Varistors Type
Introduction
SVC series Varistors are gapless ceramic surge absorbers of a new type made of metal oxide which is
designed to protect various kinds of electronic devices and semiconducting elements from surges.
Features
High discharge current capability up to 4000 Amps.
Excellent clamping characteristics.
Fast response time under 50 nanesesconds.
Improve Product safety
UL, CSA, VDE recognized
special specification like a Automobile, Medical, Military, Aviation should be discuss with our sales representatives

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.

Notes :
The power supply voltage must not exceed the maximum
allowable circuit voltage of the SVC
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 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 position.
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.
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
Application Notes
When surges exceed the rating for the SVC, short-circuits or
damages can be expected. Take following precautions.
