Product details: UNS4681V511 3BHE004074R0511 ABB overvoltage protector module
Overvoltage protectors generally have the ability to limit various overvoltage (including atmospheric overvoltage and operating overvoltage) to protect electrical equipment from overvoltage damage.
The structure adopts a combination of zinc oxide nonlinear resistance and discharge gap for mutual protection, which helps to extend the service life of the overvoltage protector.
It may have a triangular gap structure, reducing the number of discharge gaps and the influence of distributed capacitance and stray capacitance on discharge values.
Product detailed parameters: UNS4681V511 3BHE004074R0511 ABB overvoltage protector module
Model: UNS4681 V511 3BHE004074R0511
Type: Overvoltage protector module
The voltage impulse coefficient of overvoltage protectors is usually 1, and the discharge voltage values are equal under various voltage waveforms, resulting in excellent protection performance.
The gap between the product and ZnO may be installed separately to solve the sealing and explosion-proof problems of ZnO.
UNS4681V511 3BHE004074R0511 Application areas:
This type of overvoltage protector is usually applied to the protection of electrical equipment in power plants, substations, metallurgy, petrochemicals, mines, buildings, environmental protection and other fields.
