The continuous applied voltage on the two terminals of SPD should not more than the maximum continuous operating voltage Uc value.
| Quantity: | |
|---|---|
Application
The RDSCB series of backup surge protectors can selectively cut off the passing power frequency current and lightning current, and effectively protect the SPD from being fused due to abnormal transient overvoltage, and SPD starting voltage drops below the power supply due to deterioration, that increased voltage and power frequency current caused serious fire accidents.
Features
● Wide specifications matching T1/T2/T3 SPD at all levels;
● Selectively breaking of the passing current;
● Low impulse current residual voltage, high endurance, high-performance contacts, and long service life;
● Modular module, compact size, easy to install, 35m㎡ rail installation, in line with general installation requirements. ；
● With instantaneous and delayed tripping functions, accurate tripping current
