Why Choose the ABB OVR T2-T3 20-440 P TS QS Surge Protective Device?

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.

Key Advantages

  • Combined Type 2 and Type 3 surge protection in a compact modular device.
  • 20 kA maximum discharge current (Imax) for transient surge-current handling.
  • 5 kA nominal discharge current (In) using an 8/20 µs waveform.
  • 1.4 kV voltage protection level Up helps limit transient voltage reaching downstream equipment.
  • TS remote signalling enables integration with compatible monitoring systems.
  • QuickSafe pluggable construction supports straightforward inspection and cartridge replacement.

Key Features

  • ABB OVR T2-T3 QuickSafe range.
  • Combined Type 2 + Type 3 surge protective device.
  • Single protected pole.
  • 400 V AC nominal voltage.
  • 440 V AC maximum continuous operating voltage Uc.
  • 20 kA maximum discharge current Imax.
  • 5 kA nominal discharge current In.
  • 1.4 kV voltage protection level Up.
  • Visual status indication for local condition checking.
  • Remote signalling contacts with 1 NO + 1 NC configuration.

Combined Type 2 and Type 3 QuickSafe Surge Protection

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.

Typical Applications

  • Main and intermediate electrical distribution boards.
  • Protection close to sensitive terminal equipment.
  • Commercial building electrical installations.
  • Industrial control and automation panels.
  • Residential and building-services distribution systems.
  • Protection of sensitive electronic and control equipment.
  • Installations requiring remote surge protector status monitoring.
