Product Introduction
1. Summary:
RL 320-50M2-11R-B is for installation at LPZ 0A-2 or higher, protecting low voltage devices from surge damages, specially designed for TT/TN-S system (“1+1” circuit).
Applied in SPD Class I+II (Class B+C) for various power supply systems of lightning current surge protection.
Designed according to IEC 61643-11.
2. Main Character:
Single-phase protection for TT/TN system (“1+1” circuit).
High discharge capacity, quick response, pluggable design.
Double thermal disconnector devices, providing more reliable protection.
Green window changes to red when a fault occurs and provides remote alarm control contact at the same time.
3. Application:
RL 320-50M2-11R-B is applied in Class I+II (Class B+C) TT system.
4. Application Environment:
Temperature: -40℃…+80℃
Relative humidity: ≦95% (25°C)
