Why Choose the ABB OVR T2 40-275 Surge Protective Device?
The ABB OVR T2 40-275 is a compact Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations against transient overvoltages caused by indirect lightning effects and electrical switching events. Identified by ABB order code 2CTB804201R0100, this single-pole surge arrester is designed for a nominal system voltage of 230 V AC.
As part of the ABB OVR surge protection range, the OVR T2 40-275 provides dependable surge-current diversion in a compact, non-pluggable DIN rail format. It is suitable for installation in electrical distribution boards and control panels where Type 2 protection is required to reduce the risk of transient overvoltages damaging downstream electrical and electronic equipment.
The device has a 275 V AC maximum continuous operating voltage (Uc), a 20 kA nominal discharge current (In) and a 40 kA maximum discharge current (Imax) using an 8/20 µs waveform. Its 1.4 kV voltage protection level (Up) helps limit the transient voltage reaching connected equipment.

Reliable Type 2 Protection Against Transient Overvoltages
Type 2 surge protective devices are used to limit transient overvoltages caused by indirect lightning effects and electrical switching operations. By diverting surge current away from downstream circuits, an SPD helps reduce electrical stress on insulation, electronic controls and other sensitive equipment.
The ABB OVR T2 40-275 combines a 40 kA maximum discharge capability with a compact single-module design, making it suitable for installations where DIN rail space is limited. Its integrated non-pluggable construction provides a straightforward Type 2 surge protection solution for low-voltage electrical distribution systems.
Typical Applications
- 230 V AC low-voltage electrical installations.
- Main and sub-distribution boards.
- Industrial electrical control panels.
- Commercial building electrical systems.
- Automation and process-control installations.
- Protection of sensitive electronic equipment.
- Electrical systems exposed to switching and indirect lightning transients.
