Why Choose the Surge Protection Device Type 2, 40kA Imax, 1Ph, 400V, 1 Pole, Pluggable, 1 Module STPT2-40K440V-1P?
This surge protection device is engineered for robust defence against transient overvoltages in single-phase systems, featuring a high discharge capacity of 40kA (8/20µs) to safeguard sensitive electrical and electronic infrastructure. Its 400V L-N rating ensures optimal compatibility with modern low-voltage distribution networks.
The compact, pluggable 1-module design guarantees easy installation, replacement, and enhanced serviceability, minimising downtime. Ideal for industrial and commercial environments requiring reliable Type 2 surge protection conforming to latest safety standards.
Product Code: 83020110
Key Benefits
- High surge current capacity of 40kA ensures superior protection against transient overvoltages.
- Pluggable 1-module design allows for quick installation and easy replacement.
- Compact size (18 mm width) saves space in distribution boards.
- Visual indication system for easy status monitoring (Green = OK, Not green = Replace).
- Compliance with IEC Class II and UL Type 2 standards guarantees reliable performance.
- Suitable for multiple system configurations including TNS, TNC, and TT (L-N only).
Compatibility
This device is compatible with single-phase 400V AC systems and supports protection modes L-N, L-PE, and N-PE. It is designed for use in TNS, TNC, and TT system configurations (only L-N for TT). The device mounts easily on standard DIN rails and is suitable for installations requiring up to 125 A back-up fuse protection.

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.
