Why Choose the ABB OVR T1-T2 N 50-275s C QS Surge Protection Cartridge?
The ABB OVR T1-T2 N 50-275s C QS is a high-performance combined Type 1+2 neutral surge protection cartridge designed for use with compatible ABB OVR QuickSafe surge protective devices. As part of the advanced ABB OVR QuickSafe surge protection range, it provides N-PE protection against lightning currents and transient overvoltages in low-voltage electrical installations.
Designed as a replaceable neutral protection cartridge, the OVR T1-T2 N 50-275s C QS enables the neutral-to-protective-earth protection element in compatible ABB OVR assemblies to be replaced without changing the complete surge protective device. This modular construction supports straightforward maintenance while retaining coordinated Type 1 and Type 2 protection within the installation.
With an impulse current (Iimp) of 50 kA using a 10/350 µs waveform and a 275 V AC maximum continuous operating voltage, the OVR T1-T2 N 50-275s C QS is designed for demanding N-PE lightning and surge protection applications. The cartridge is supplied under ABB order code 2CTB815710R2700.

Combined Lightning and Surge Protection for N-PE Applications
Combined Type 1+2 surge protection is designed to address both high-energy lightning currents and transient overvoltages within low-voltage electrical installations. Type 1 capability enables the protection system to handle lightning impulse currents characterised by a 10/350 µs waveform, while Type 2 protection helps limit lower-energy transient surges that could otherwise damage downstream electrical and electronic equipment.
The ABB OVR T1-T2 QuickSafe range provides modular protection for coordinated electrical installations. The OVR T1-T2 N 50-275s C QS serves as the N-PE protection cartridge in compatible assemblies, combining a high 50 kA lightning impulse current capability with replaceable construction for convenient maintenance.
