Frequently Asked Questions
What does Type 1+2 surge protection mean?
Type 1+2 surge protection devices combine the capabilities of both Type 1 and Type 2 SPDs, providing protection against high-energy lightning strikes and lower energy switching surges.
Can this device be used in three-phase systems?
No, this specific model is designed for single-phase TT systems with 2 poles and is not suitable for three-phase configurations.
How does the remote indication feature work?
The device includes a microswitch that changes state when the SPD requires replacement, allowing remote monitoring systems to detect its status.
What is the significance of the 25 kA Lightning Impulse Current rating?
This rating indicates the maximum impulse current the device can safely handle from lightning strikes, ensuring high-level protection for connected equipment.

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.
