CRITEC® DDI Series – Decoupling Inductor
Decoupling inductors are installed between spark gap and MOV protection devices to ensure correct coordination. If less than 10 meters of wiring exists between a spark gap and downstream MOV device, then decoupling inductors should be installed. As the decoupling inductors are installed in series with the load, two units are available, a compact unit for circuits up to 35A and a larger unit for 63A circuits.
- Decoupling of spark gaps and MOVs – allows correct coordination of different SPD technologies
- 35mm2 tunnel terminals – accepts large cable size
- 63A features top and bottom terminals – flexible installation
- 35mm DIN 43880 profile – matches triggered spark gap and DSD range
