Why Choose the ABB OVR T2 40-275 P QS Surge Protective Device?
The ABB OVR T2 40-275 P QS, order code 2CTB803871R2300, is a single-pole, pluggable Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages. Part of the ABB OVR range and ABB's Surge Protection Devices product group, it is designed for use on 230 V AC networks.
The OVR T2 40-275 P QS provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA using an 8/20 µs surge current waveform. Its 1.25 kV voltage protection level (Up) helps limit transient voltage reaching downstream equipment, while the 275 V maximum continuous operating voltage (Uc) is suited to standard 230 V AC installations.
Featuring a replaceable pluggable cartridge and ABB QuickSafe technology, this compact SPD supports efficient installation and maintenance. With a width of just 17.8 mm and mounting on a standard 35 mm DIN rail, it integrates neatly into distribution boards, consumer units and industrial control panels.
