Approvals & Standards
- IEC 61643-11
- EN 61643-11
Key features & benefits
STP T23 20 is the series of combined Type 2+3/Class II+III devices for discharging voltage surges while providing a very fine voltage protection level, in accordance with EN/IEC 61643-11. Suitable as the final stage of protection in panels with Type 2 protection devices installed upstream such as STP T2 40 SPDs. These SPDs should be installed as close as possible to the equipment being protected. LCF Leakage current free T1+2 (no electrial loses)
