The ABB OVR T2 40-440s C QS, order code 2CTB815704R5500, is a replaceable Type 2 / Class II surge protection cartridge from the ABB OVR QuickSafe range. Designed for compatible ABB OVR pluggable surge protection assemblies, this single-pole cartridge provides protection against transient overvoltages associated with indirect lightning and electrical switching events.
The OVR T2 40-440s C QS provides a 20 kA nominal discharge current (In) and a 40 kA maximum discharge current (Imax) with an 8/20 µs waveform, together with a 2 kA impulse current (Iimp) using a 10/350 µs waveform. ABB specifies a 400 V AC system voltage, 440 V AC maximum continuous operating voltage (Uc) and a 1.5 kV voltage protection level (Up).
The cartridge incorporates ABB's Safety Reserve and preventive-maintenance functionality, along with visual status indication for straightforward condition checking. Its replaceable cartridge format allows a compatible OVR SPD to be serviced without replacing the complete surge protection assembly, supporting efficient maintenance in TT, TN-C, TN-S and compatible IT low-voltage networks.
Type 2 surge protection devices are designed to limit transient overvoltages associated with indirect lightning and electrical switching events. They are commonly installed in distribution equipment to divert surge current away from sensitive downstream electrical and electronic equipment. A replaceable cartridge allows the active protection element to be renewed while retaining the compatible installed SPD base.
The ABB OVR T2 40-440s C QS combines a 40 kA maximum 8/20 µs discharge current with Safety Reserve and preventive-maintenance functionality. The cartridge is used as the phase replacement element in compatible ABB OVR assemblies, including the OVR T2 40-440s P QS family, allowing surge protection to be restored quickly without disturbing the permanent wiring to the SPD base.
