Product Introduction
This series of surge protectors is suitable for TT, IT, TN-S, N-C-S and other power supply systems with AC 50Hz, 380V and below, and can be used as equipotential connections at the interface of LPZ1, LP22 and LP23 zones. Its design basis complies with IEC61643-1, GB18802.1， The shell is designed to be installed on a 35mm electrical rail, and the product has a built-in failure release device. When the surge protector fails due to overcurrent, overheating, or breakdown, the failure release device can automatically disconnect it from the power grid, and the visual alarm indicator window changes from green (normal) to red (fault).
Product Features
a、 Can withstand up to 80kA (8/20us) lightning current surge;
b、 Action response time less than 25 nanoseconds;
c、 The color of the visual window indicates the working status of the protection, green (normal) and red (fault).
d、 High energy surge protection
e、 Remote signaling alarm interface
f、 Failure detection indication
9. Standard modular installation
h、 Reaction speed: nanosecond level
i、 Built in instantaneous overcurrent circuit breaker device
j、 The maximum discharge current of a single module is 80kA (8/20 μ S)
k、 Built in overheat circuit breaker device
Normal working conditions
1. The ambient air temperature ranges from -40 ℃ to+70 ℃, with an average value not exceeding+35 ℃ within 24 hours.
2. The altitude shall not exceed 2000m.
3. The relative humidity of the air at the installation site under atmospheric conditions shall not exceed 50% at a maximum temperature of+40 ℃; Higher relative humidity is allowed at lower temperatures, with the average lowest temperature of the wettest month not exceeding+25 ℃ and the average maximum relative humidity of that month not exceeding 90%. And taking into account the condensation that occurs on the surface of the product due to temperature changes.
4. Pollution level: Level 2.
5. Installation category: Category II
6. Installation method: Adopting international standard guide rails.
