Why Choose the ABB OVR T2 40-440 C QS Surge Protective Device?
The ABB OVR T2 40-440 C QS, order code 2CTB803876R0400, is a Type 2 surge protective device (SPD) replacement cartridge from ABB's OVR surge protection range. Designed for use with compatible OVR Type 2 assemblies, it provides protection for electrical installations and connected equipment against transient overvoltages caused by indirect lightning effects and switching events.
The OVR T2 40-440 C QS uses ABB's QuickSafe technology and a plug-in cartridge format, allowing a protection module to be replaced without replacing the complete compatible SPD assembly. A mechanical status indicator provides straightforward visual indication of the cartridge condition, helping simplify inspection and maintenance in electrical distribution systems.
This single-pole cartridge has a maximum continuous operating voltage of 440 V AC, a nominal discharge current (In) of 20 kA with an 8/20 µs waveform and a maximum discharge current (Imax) of 40 kA. It is suitable for surge protection applications in TT, TN-C, TN-S and IT low-voltage distribution systems when installed as part of the appropriate ABB OVR assembly.

Reliable Type 2 Surge Protection
Type 2 surge protective devices are used to limit transient overvoltages within low-voltage electrical installations. They divert surge currents generated by indirect lightning effects and switching operations, helping prevent damaging voltage levels from reaching sensitive electrical and electronic equipment.
The ABB OVR T2 platform combines pluggable protection modules with visual status indication to simplify maintenance. The OVR T2 40-440 C QS cartridge can be replaced in a compatible assembly when required, reducing maintenance effort while restoring the surge protection function without replacing the complete device.
Typical Applications
Replacement cartridge for compatible ABB OVR Type 2 surge protective devices.
Low-voltage electrical distribution boards.
Commercial and industrial electrical installations.
Sub-distribution panels and final distribution circuits.
Protection of automation and control equipment against transient overvoltages.
Protection of electrical and electronic loads from switching surges.
TT, TN-C, TN-S and IT distribution systems.
