Frequently Asked Questions
What does leakage current free mean in this SPD?
Leakage current free means the SPD does not allow any continuous current to flow through it during normal operation, preventing nuisance tripping of upstream protection devices and enhancing system reliability.
Can this device be used on DC systems?
No, the STPT23-20K275V-4P-LF is designed specifically for AC systems with a nominal voltage of 230/400V.
How do I know when the surge protection device needs replacing?
The device features an indication system that shows green when operational. If the indicator is not green, it signals that the SPD needs replacement.
Is the device suitable for installation in outdoor environments?
This SPD is intended for installation within electrical panels and enclosures; ensure the enclosure provides adequate protection against environmental factors if used outdoors.

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.
