Notice for use
To avoid damage to other equipment due to fire or deterioration caused by varistor, please refer to and
observe the following principles:
1) When a high current or high voltage flows into the varistor, the varistor itself may be damaged, heated,
smoke, catch fire and burst.
To avoid this, fuses or circuit breakers can be installed at both ends of the varistor or power supply;
The fuses of the following specifications are for reference only:
Diameter 05D 07D 10D 14D 20D
Rated current of fuse
1-2A 2-3A 3-5A 3-10A 5-15A
2) Do not allow the current and energy flowing into the varistor to exceed its rated value.
3) The marked VDR product brand names and marks are all patent applications of the company.
Customers who use or sell VDR products that are not specifically designated for such app.
