Why Choose the Surge Protection Device Type 1+2 STPT12-25K275V-2P?
Engineered for robust overvoltage defence, the STPT12-25K275V-2P offers reliable Type 1+2 surge protection with a high impulse discharge current of 25kA (10/350 μs) for 1Ph+N, 230V applications in 2+0 TNS systems.
This pluggable, two-pole device streamlines installation, minimises downtime, and ensures consistent protection for vital electrical infrastructure in both industrial and commercial environments.
Product Code: 83120156
Key Benefits
- High impulse discharge current capacity of 25kA (10/350 μs) ensures superior surge protection.
- Pluggable design allows for quick and easy installation and replacement.
- Visual indication system with green (OK) / not green (replace) status for easy maintenance.
- Compact size with 4 modules fits standard DIN rail mounting systems.
- Supports 2+0 TNS system configuration, ideal for 230V single-phase applications.
- Robust housing material (PA66 CT1) for durable and safe operation.
Compatibility
The STPT12-25K275V-2P is compatible with 1Ph+N, 230V electrical systems configured in 2+0 TNS arrangements. It is suitable for integration into industrial and commercial power distribution boards equipped with DIN rail mounting and supports back-up fuses up to 315 A [gG]. Replacement plugs such as model 83120007 ensure extended device lifecycle.
Applications
- Industrial power distribution systems requiring Type 1+2 surge protection.
- Commercial buildings and facilities with 230V single-phase supply.
- Protection of sensitive electrical and electronic equipment from transient overvoltages.
- Renewable energy installations needing robust surge protection devices.
- Infrastructure projects demanding compliance with IEC SPD Class I+II standards.

Frequently Asked Questions
What is the primary function of the STPT12-25K275V-2P?
It provides surge protection by safely diverting transient overvoltages away from sensitive electrical equipment in 230V single-phase systems.
Can this device be installed on any DIN rail system?
Yes, it is designed for standard DIN rail mounting, making it compatible with most industrial and commercial distribution boards.
How do I know when the device needs replacement?
The device features a visual indication system; a green indicator means it is operational, while a non-green indicator signals replacement is necessary.
Is the STPT12-25K275V-2P suitable for three-phase systems?
No, this model is intended for single-phase plus neutral (1Ph+N) systems only.

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.
