Why Choose the ABB OVR T1-T2 4L 100-255 P TS Surge Protective Device?
The ABB OVR T1-T2 4L 100-255 P TS is a high-capacity combined Type 1 + Type 2 surge protective device (SPD) designed to protect three-phase low-voltage electrical installations against lightning currents and transient overvoltages. Identified by ABB order code 2CTB812101R2300, this four-pole device is designed for TN-S distribution systems with a nominal system voltage of 230/400 V AC.
The device combines Type 1 lightning-current protection and Type 2 surge protection in a pluggable DIN rail assembly. Each protected path provides an impulse discharge current (Iimp) of 25 kA using a 10/350 µs waveform, giving a total lightning-current discharge capability of 100 kA across the four protected poles.
For transient surge protection, the OVR T1-T2 4L 100-255 P TS provides a 25 kA nominal discharge current (In) and a 60 kA maximum discharge current (Imax) per protected path using an 8/20 µs waveform. A 1.5 kV voltage protection level (Up), replaceable protection modules, local status indication and integrated TS remote signalling contacts make it particularly suitable for demanding commercial and industrial power-distribution applications.

Reliable Type 1 and Type 2 Protection for Power Distribution Systems
Combined Type 1 and Type 2 SPDs provide protection against both high-energy lightning-current impulses and lower-energy transient overvoltages. Type 1 performance is tested using the 10/350 µs lightning-current waveform, while Type 2 performance uses the 8/20 µs surge-current waveform. Combining both functions in one device helps provide coordinated protection at the electrical installation level.
The ABB OVR T1-T2 4L 100-255 P TS provides 25 kA Iimp per protected pole and 100 kA total lightning-current capability, together with a 1.5 kV protection level. Its pluggable construction simplifies maintenance, while visual indication and TS remote contacts allow protection status to be checked locally or integrated into a remote monitoring system.
Typical Applications
- 230/400 V AC TN-S electrical distribution systems.
- Main low-voltage distribution boards.
- Commercial and industrial switchboards.
- Industrial automation and control installations.
- Building electrical distribution systems.
- Installations requiring combined Type 1 and Type 2 surge protection.
- Systems requiring remote monitoring of surge protective device status.
