Why Choose the ABB OVR T2 3L 40-275 P QS Surge Protective Device?
The ABB OVR T2 3L 40-275 P QS, order code 2CTB803873R2400, is a three-pole, pluggable Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning effects and switching events. Part of the ABB OVR range and ABB's Surge Protection Devices product group, it is designed for three-phase 230/400 V AC TN-C networks.
The OVR T2 3L 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 its 275 V AC maximum continuous operating voltage (Uc) suits 230/400 V AC three-phase installations.
Featuring three protected poles, replaceable pluggable protection modules and ABB QuickSafe technology, this SPD combines high surge-current handling with convenient maintenance. Mechanical status indicators provide clear local indication of each protection module's condition, while the compact DIN-rail format integrates efficiently into three-phase distribution boards and industrial control panels.
