Frequently Asked Questions
What does the 40kA Imax rating mean?
The 40kA Imax rating indicates the maximum surge current the device can safely divert during a transient event, providing high-level protection against power surges.
Is this device suitable for single-phase systems?
No, this particular model is designed for three-phase TNC systems and is not suitable for single-phase installations.
How does the remote indication feature work?
The remote indication uses a microswitch that changes state when the device needs replacement, allowing status monitoring from a remote location.
Can the replacement plugs be purchased separately?
Yes, replacement plugs for N-PE and L-N are available under part numbers 77707664 and 77707671 respectively.

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.
