Why Choose the ABB OVR T2 40-275s C QS Replacement Surge Protection Cartridge?
The ABB OVR T2 40-275s C QS is a single-pole replacement cartridge for compatible ABB OVR Type 2 surge protective devices (SPDs). Identified by ABB order code 2CTB815704R2600, it is designed for 230/400 V AC low-voltage installations and restores the protection function of compatible OVR T2 40-275s pluggable surge protection assemblies.
The cartridge provides a 20 kA nominal discharge current (In) and 40 kA maximum discharge current (Imax) using an 8/20 µs waveform, together with a 2 kA impulse current (Iimp) using a 10/350 µs waveform. Its 275 V AC maximum continuous operating voltage and 1.4 kV voltage protection level (Up) make it suitable for compatible 230/400 V AC surge protection systems.
ABB's QuickSafe technology and Safety Reserve functionality provide integrated thermal protection and preventive-maintenance indication. The pluggable cartridge format allows a worn protection module to be replaced without changing the complete SPD base, while the integrated status indicator provides a clear local indication of cartridge condition.

Reliable Replacement Protection with Safety Reserve Functionality
Type 2 SPDs protect low-voltage installations against transient overvoltages associated with indirect lightning effects and electrical switching events. The ABB OVR T2 40-275s C QS provides a 20 kA nominal discharge current and 40 kA maximum discharge current, helping compatible ABB OVR assemblies limit transient voltage while maintaining their specified protection performance.
The cartridge incorporates ABB's Safety Reserve preventive-maintenance functionality, together with QuickSafe technology and local status indication. Because the protection element is pluggable, a cartridge requiring replacement can be removed from its compatible base and exchanged independently, reducing the amount of hardware that must be replaced during routine SPD maintenance.
