The ABB OVR T2-T3 20-440 P TS QS 2CTB803871R1300 is a combined Type 2 and Type 3 surge protective device (SPD) designed to protect low-voltage electrical installations and sensitive downstream equipment against transient overvoltages. Part of ABB's OVR QuickSafe range, this single-pole SPD combines Type 2 surge-current handling with Type 3 protection characteristics in a compact DIN-rail format.
Designed for 400 V AC nominal applications, the OVR T2-T3 20-440 P TS QS has a maximum continuous operating voltage Uc of 440 V AC. It provides a maximum discharge current Imax of 20 kA and a nominal discharge current In of 5 kA using an 8/20 µs waveform, together with a voltage protection level Up of 1.4 kV.
The QuickSafe (QS) pluggable design enables convenient cartridge replacement, while the TS configuration provides remote signalling through integrated auxiliary contacts. A visual status indicator provides local condition information, making the 2CTB803871R1300 particularly suitable for distribution boards and installations where both local and remote monitoring of surge protection status are valuable.
Combined Type 2 and Type 3 SPDs provide surge-current handling for distribution-level protection while also offering a low voltage protection level suitable for protecting sensitive downstream equipment. They can be installed in distribution boards and close to terminal equipment as part of a coordinated surge protection concept.
The ABB OVR T2-T3 20-440 P TS QS combines a 20 kA Imax, 5 kA In and 1.4 kV Up in a compact 17.8 mm module. QuickSafe pluggable construction, visual status indication and TS remote signalling make it particularly practical where straightforward maintenance and continuous SPD condition monitoring are required.
