Why Choose the ABB OVR T1-T2 3L 12.5-275s P QS Surge Protective Device?
The ABB OVR T1-T2 3L 12.5-275s P QS, order code 2CTB815710R1800, is a combined Type 1 and Type 2 surge protective device (SPD) designed to protect three-phase low-voltage electrical installations against high-energy lightning currents and transient overvoltages. Part of the ABB OVR QuickSafe surge protection range, it combines Type 1 lightning-current protection with Type 2 overvoltage protection in a compact three-pole DIN-rail-mounted assembly.
The device protects L1, L2 and L3 and is rated for 230/400 V AC systems. Its pluggable construction enables protection modules to be replaced when required, while ABB QuickSafe technology incorporates an end-of-life indicator and patented Safety Reserve system to support preventive maintenance and dependable operation.
With a maximum continuous operating voltage (Uc) of 275 V AC, an impulse current (Iimp) of 12.5 kA using a 10/350 µs waveform, a maximum discharge current (Imax) of 80 kA and a nominal discharge current (In) of 30 kA, the OVR T1-T2 3L 12.5-275s P QS provides substantial surge-handling capability. Its low 1.1 kV voltage protection level (Up) helps limit the residual voltage presented to downstream electrical equipment.
Key Advantages
Combined Type 1 and Type 2 surge protection in one compact device.
12.5 kA impulse current (Iimp) for 10/350 µs lightning-current impulses.
80 kA maximum discharge current (Imax) for high transient-current capability.
30 kA nominal discharge current (In) for 8/20 µs surge currents.
Maximum continuous operating voltage (Uc): 275 V AC.
Impulse current (Iimp, 10/350 µs): 12.5 kA.
Maximum discharge current (Imax, 8/20 µs): 80 kA.
Nominal discharge current (In, 8/20 µs): 30 kA.

Combined spark-gap and varistor surge-protection technology.
Pluggable, replaceable protection modules.
QuickSafe end-of-life indication with Safety Reserve.
DIN-rail mounting for System pro M compact installations.
IP20 degree of protection.
Combined Lightning and Surge Protection for Three-Phase Systems
Type 1 surge protective devices are designed to discharge high-energy currents associated with lightning, while Type 2 devices protect against lower-energy transient overvoltages caused by indirect lightning effects and switching operations. The ABB OVR T1-T2 3L 12.5-275s P QS combines both functions, allowing it to provide coordinated protection at main or appropriate sub-distribution boards.
Its 1.1 kV protection level combines with high lightning-current and surge-current capability to help protect downstream installations. Pluggable modules simplify maintenance, while ABB's QuickSafe end-of-life indication and Safety Reserve system help maintenance personnel identify deterioration and plan replacement before complete loss of surge protection.
