Why Choose the ABB OVR T1-T2 12.5-440s P QS Surge Protective Device?
The ABB OVR T1-T2 12.5-440s P QS, order code 2CTB815710R4100, is a high-performance combined Type 1 and Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations against lightning currents and transient overvoltages. As part of the ABB OVR QuickSafe surge protection range, this single-pole device combines high-energy lightning-current protection with Type 2 surge suppression in a compact, pluggable DIN-rail format.
The device incorporates ABB's QuickSafe technology and Safety Reserve system, providing integrated thermal disconnection, end-of-life indication and continued basic protection through a reserve varistor before replacement is required. Its pluggable construction enables the protection cartridge to be replaced without changing the complete installed base, helping simplify preventative maintenance and minimise downtime.
With a maximum continuous operating voltage (Uc) of 440 V AC, 12.5 kA impulse current (Iimp), 20 kA nominal discharge current (In) and 80 kA maximum discharge current (Imax), the OVR T1-T2 12.5-440s P QS provides substantial surge-handling capability. A 1.9 kV voltage protection level (Up) helps limit residual transient voltage reaching downstream electrical and electronic equipment.

Combined Lightning and Surge Protection for Electrical Systems
Type 1 surge protective devices are designed to discharge high-energy lightning currents entering an electrical installation, while Type 2 protection limits transient overvoltages caused by indirect lightning effects and electrical switching. The ABB OVR T1-T2 12.5-440s P QS combines both functions, providing coordinated lightning-current and transient-overvoltage protection from a single DIN-rail-mounted device.
ABB's QuickSafe and Safety Reserve technologies add practical maintenance benefits. The pluggable cartridge can be replaced when required, while the integrated end-of-life indicator provides a clear visual indication of device condition. The Safety Reserve system maintains basic surge protection through an additional varistor when the primary protection stage reaches the end of its service life, allowing replacement to be planned while helping reduce unprotected downtime.
