TSU1 Surge Protector SPD is mainly applied to limiting amplitude value of transient over voltage, absorbing, consuming, discharging surging current energy in the electric wiring of AC 50/60Hz, rated working voltage 230V, surging through flow capacity not more than 50A.
Used in high overvoltage applications to convert the protected electrical components from one overvoltage to another lower overvoltage.
It is adapted for composing combined electrical equipment with other module terminal electrical equipment so that it can increase installation types and expand range of using, or further step down overvoltage on using terminals to protect TV set, hi-fi sound and such kinds of electrical appliances or the facilities like computer, microcomputer.
Protector applies to power utilization for household and the similar places, facilities for inputting circuit in the thunder direct stroke or protecting from the damage of the surging current caused by outdoor arrester. The products comply with IEC61643.
