Frequently Asked Questions
What does the 12.5kA impulse current rating mean?
The 12.5kA impulse current rating (10/350μs) indicates the maximum surge current the device can safely handle from lightning strikes or other transient events without damage.
Can this device be used in single-phase systems?
This device is specifically designed for 3-phase plus neutral (3Ph+N) TNS systems and is not suitable for single-phase installations.
How does the remote indication system work?
The device features a microswitch that changes state based on the status of the surge protection modules, allowing remote monitoring of whether the device is functioning correctly (green) or needs replacement (not green).
Is the device RoHS compliant?
Yes, the STPT12-12K150V-4PM is fully RoHS compliant, ensuring it meets environmental and safety standards.

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.
