Frequently Asked Questions
What does Type 1 surge protection mean?
Type 1 surge protection devices are designed to protect electrical installations from direct lightning strikes and high-energy surges by safely diverting large transient currents.
Can this device be used in three-phase systems?
This specific model is designed for single-phase 230V systems with L-N protection and is not suitable for three-phase systems.
How do I know if the device is functioning correctly?
The device includes a visual status indicator that shows whether the SPD is operational or needs replacement.
Is the installation tool-free?
The device mounts on a standard DIN rail and requires a torque of 3 Nm for secure terminal connections, so a suitable screwdriver is necessary.

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.
