Introduction
Reliance Industrial facilities, business infrastructure, and information facility are highly dependent on reliable installations of electrical supply. Lightning and fluctuations in electricity can bring destruction, time losses, and hazards.
Awareness of relationship between Uc, Up, In, and Imax ratings of surge protections devices allow engineers to choose the right surge protection device (SPD) for electrical safety.
Understanding Key SPD Ratings
- Uc (Maximum Continuous Operating Voltage): This is the highest voltage in the RMS range that a surge protective device can endure across its terminals without experiencing any issues.
- Up (Voltage Protection Level): This is the maximum value of voltage protection level achieved after the specific tests are carried out. A lower Up is known to provide better protection when coordination is done at the equipment withstand levels.
- In (Nominal Discharge Current): This is the peak of a specific discharge surge current (8/20µs) number used to determine the SPD’s discharge capabilities in the long run.
- Imax (Maximum Discharge Current): This is the maximum peak of a discharge current (8/20µs) a Type 2 SPD can endure during a certain test.
