Why Choose the ABB OVR T2 40-275 C QS Replacement Cartridge?
The ABB OVR T2 40-275 C QS, order code 2CTB803876R1000, is a single-pole replacement surge protection cartridge for compatible ABB OVR Type 2 surge protective devices. Part of the ABB OVR QuickSafe range and ABB's Surge Protection Devices product group, it provides a replaceable phase protection element for low-voltage AC installations.
The OVR T2 40-275 C QS provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA using an 8/20 µs waveform. It has a 275 V AC maximum continuous operating voltage (Uc) and a 1.25 kV voltage protection level (Up), supporting effective protection against transient overvoltages in compatible ABB OVR assemblies.
Its compact pluggable construction allows a protection cartridge to be replaced while retaining the compatible installed SPD base and associated wiring. Integrated status indication simplifies routine inspection, while the cartridge's 100 kA short-circuit withstand capability and compliance with IEC 61643-11 and EN 61643-11 make it suitable for demanding low-voltage surge protection applications.

Serviceable Type 2 Surge Protection for Low-Voltage Systems
Type 2 surge protective devices are designed to protect electrical installations and sensitive equipment against transient overvoltages, particularly those associated with indirect lightning effects and electrical switching events. They are characterised by their ability to safely discharge surge current with an 8/20 µs waveform while limiting the residual voltage applied to downstream equipment.
The OVR T2 40-275 C QS provides the replaceable phase protection element for compatible ABB OVR Type 2 assemblies. Its 40 kA maximum discharge current, 275 V AC maximum continuous operating voltage and compact pluggable design make it a practical maintenance component for commercial, industrial and other low-voltage surge protection installations.
