PRODUCT OVERVIEW
NYKU1 series surge protector, also known as lightning protector, is an electrical component capable of suppressing transient overvoltage and lightning strikes. It is mainly installed in circuits to protect electronic equipment from overvoltage and overcurrent.
PRODUCT CHARACTERISTICS
Fast response
Surge protectors are able to react in a very short time (nanoseconds) to ensure that voltage surges are blocked or attenuated before they damage the equipment.
Low residual voltage,
high withstand voltage
It’s conducive to prevent electrical fires caused by excessive voltage by limiting voltage spikes.
High-energy contacts
for long service life
Frequent voltage fluctuations can gradually damage the internal components of load electronic equipment, and surge protectors can minimize the damage and extend the service life of the equipment.
Small size, full range
of specification, easy to use
Modular module meets the mounting requirements of general 35mm guide rail, which is easy to use and maintain.
