SA-P 6 kV 0.8 C HL2
Surge arresters OPN-P 6 kV 0.8 C UHL2 are designed to protect the insulation of electrical installations in 6 kV AC networks with a frequency of 50 Hz and isolated neutral from switching and lightning overvoltages. They are manufactured according to TU 27.12.10-057-21639232-2022 and comply with the requirements of GOST R 52725-2021.
Technical specifications:
- Rated discharge current: 10 kA
- Energy discharge class: 2
- Safe failure current:
- duration of at least 1 second — at least 0.6 kA
- duration of at least 0.2 seconds — at least 20 kA
- Impulse current 4/10 µs: 100 kA
- Thermal charge, at least: 1.1 C
These surge arresters provide reliable protection of electrical installations from overvoltages resulting from lightning strikes and switching operations.
