Why Choose the ABB OVR T1-T2 N 100-255 P TS Surge Protection Device?
The ABB OVR T1-T2 N 100-255 P TS, order code 2CTB813011R2300, is a pluggable Type 1+2 surge protection device (SPD) designed for neutral-to-earth protection in low-voltage TT and TN-S electrical systems. Using spark-gap technology, it combines high lightning-current discharge capability with a low residual voltage to provide coordinated protection at main and subdistribution boards.
Designed for 230/400 V AC networks, the OVR T1-T2 N 100-255 P TS provides an exceptional 100 kA impulse current (Iimp) with a 10/350 µs waveform between neutral and protective earth. It also has a 100 kA nominal discharge current (In) with an 8/20 µs waveform and a maximum continuous operating voltage (Uc) of 255 V AC.
The device provides a voltage protection level (Up) of ≤1.5 kV and incorporates a visual end-of-life indicator for straightforward condition checking. The TS version includes remote signalling contacts, allowing SPD status to be incorporated into monitoring or alarm systems, while its pluggable construction enables convenient replacement of the protection cartridge when required.

High-Capacity Type 1+2 Neutral-to-Earth Surge Protection
Type 1+2 surge protection devices combine the ability to discharge high-energy lightning currents with protection against transient overvoltages. The ABB OVR T1-T2 N 100-255 P TS is specifically configured for neutral-to-earth protection, using spark-gap technology to handle substantial lightning-current impulses while maintaining a voltage protection level of ≤1.5 kV.
The device is typically installed within main AC distribution switchboards or subdistribution boards as part of a coordinated surge protection system. Its 100 kA 10/350 µs impulse-current capability, visual condition indication and remote signalling contacts make it particularly suitable for installations where high-capacity surge protection and ongoing SPD status monitoring are required.
Typical Applications
230/400 V AC TT electrical distribution systems.
230/400 V AC TN-S electrical distribution systems.
Neutral-to-earth protection in coordinated SPD installations.
Main AC distribution switchboards.
Subdistribution boards.
Commercial and industrial electrical installations.
Installations requiring remote SPD status signalling.
Protection against high-energy lightning currents and transient overvoltages.
