Why Choose the ABB OVR T1-T2 3N 12.5-275s P QS Surge Protective Device?
The ABB OVR T1-T2 3N 12.5-275s P QS, order code 2CTB815710R1900, is a combined Type 1 and Type 2 surge protective device (SPD) designed to protect three-phase low-voltage electrical installations with neutral against lightning currents and transient overvoltages. As part of the ABB OVR QuickSafe surge protection range, it combines lightning-current protection and Type 2 surge protection in a coordinated DIN-rail-mounted assembly.
The 3N configuration provides protection for all three phase conductors together with the neutral path, making the device suitable for three-phase plus neutral distribution systems. Its pluggable construction supports straightforward servicing and replacement of protection modules, while integrated mechanical status indication enables convenient visual inspection of the SPD condition.
With a maximum continuous operating voltage (Uc) of 275 V AC and an impulse current (Iimp) of 12.5 kA using the 10/350 µs lightning-current waveform, the OVR T1-T2 3N 12.5-275s P QS is designed for high-energy surge protection at the origin of appropriate installations. Its combined Type 1+2 performance helps protect downstream electrical and electronic equipment against both lightning-current impulses and transient overvoltages.
Key Advantages
Combined Type 1 and Type 2 surge protection in a single coordinated device.
12.5 kA impulse current (Iimp) capability for 10/350 µs lightning-current impulses.
275 V AC maximum continuous operating voltage (Uc).
3N configuration for three-phase electrical systems with neutral.
Designed to protect installations against lightning currents and switching-induced transient overvoltages.
Pluggable protection modules simplify servicing and replacement.
Mechanical status indication provides straightforward local condition monitoring.
ABB QuickSafe technology supports dependable protection and safe end-of-life management.
DIN-rail construction enables convenient integration into electrical distribution boards.
DIN-rail mounting for electrical distribution-board installation.
Suitable for coordinated lightning and transient overvoltage protection.
Combined Lightning and Surge Protection for Three-Phase 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 associated with indirect lightning effects and switching operations. The ABB OVR T1-T2 3N 12.5-275s P QS combines both functions to provide coordinated protection for three-phase plus neutral electrical distribution systems.
The OVR QuickSafe range is designed to combine effective surge protection with practical maintenance. Its pluggable construction allows protection modules to be replaced when required, while local mechanical indication enables maintenance personnel to check the operating condition of the device during routine inspection.
