Frequently Asked Questions
What does the 40kA Imax rating mean?
The 40kA Imax rating indicates the maximum surge current the device can safely handle during a transient event, measured with an 8/20 microsecond waveform.
Is this SPD suitable for use in residential installations?
This SPD is primarily designed for industrial and commercial three-phase systems; it may not be suitable for typical residential single-phase systems.
How does the indication system work?
The device features a visual indicator that shows green when the SPD is functioning correctly and changes colour to signal when replacement is necessary.
Can the modules be replaced individually?
Yes, the pluggable modular design allows for individual module replacement without disturbing the entire system.

Protection system of coordinated stages: Type 1, 2 and 3 SPDs
The SPDs of a surge protection system must be able to withstand the discharged current and provide a Ures level (residua l voltage) lower than the Ue peak voltage that the equipment can withstand. Most of the times it is not possible to achieve this with just one SPD, especially because the intensity of the surge is not known, and because of the induction of overvoltages when conductors exceed 10m.
The optimal system of protection is the 3-STEP approach, in which successive stages are combined in the performance of high discharge capacity devices and devices with an optimal voltage protection level (low). This is addressed by the definition of "Types" or "Classes" of SPDs according to the type of transient pulses to which each protected zone in the installation is subject to.
