The ESP 240CDT2/40/TT is a Type 2 /Class II tested compact Surge Protective Device SPD(to BS EN/IEC 61643) for use on the sub-distribution board.
For use at boundaries up to LPZ 1 through to LPZ 2 to protect electrical equipment from damage.
Features & Benefits
- Ultra-compact, space-saving design to fit within distribution panel boards and Electric Vehicle EV charging stations.
- An indicator shows when the SPD protection modules require replacement.
- Remote signal contact can indicate the protector’s status through interfacing with a building management system.
- Innovative locking DIN rail clip allows easy SPD positioning then securing.
Application
- Use on single-phase mains supplies and power distribution systems for protection against indirect lightning strikes.
- ESP 240CDT2/40/TNS and ESP 240CDT2/40/TT versions also cover TN-C-S earthing systems.
Installation
The SPD is to be installed in the sub-distribution board with connecting leads of minimal length. The protector should be fused and is suitable for attachment to a 35 mm top hat DIN rail.
