Why Choose the Surge Protection Device Type 2+3 STPT23-20K320V-1PM?
The STPT23-20K320V-1PM is engineered for effective protection of single-phase 230/277V power systems against transient overvoltages. With a maximum discharge current (Imax) of 20kA (8/20μs), it ensures reliable safeguarding of sensitive equipment in commercial and industrial installations.
This compact, pluggable, 1-pole SPD offers straightforward DIN rail mounting, rapid replacement, and remote fault indication for simplified diagnostics and maintenance. Ideal for robust protection where space and fast serviceability are essential.
Product Code: 83230103
Key Benefits
- High surge current capacity of 20kA ensures robust protection against transient overvoltages.
- Compact and pluggable design allows for easy installation and quick replacement on DIN rails.
- Remote fault indication simplifies maintenance and reduces downtime.
- Suitable for single-phase 230/277V systems, compatible with multiple system configurations.
- Reliable indication system with green (OK) and microswitch for replacement alerts.
Compatibility
This Surge Protection Device is compatible with TNS, TNC, and TT power system configurations, specifically designed for L-N protection. It supports single-phase 230/277V AC systems and can be integrated with backup fuses up to 63 A [gG].
Applications
- Commercial and industrial electrical installations requiring surge protection.
- Protection of sensitive electronic equipment in power distribution panels.
- Use in systems with limited space where compact, modular devices are preferred.

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.
