2CTB803873R2500 ABB OVR T2 3L 40-275 P TS QS Type 2 Surge Protective Device

Why Choose the ABB OVR T2 3L 40-275 P TS QS Surge Protective Device?

The ABB OVR T2 3L 40-275 P TS QS, order code 2CTB803873R2500, 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 TS 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 AC maximum continuous operating voltage (Uc) is suited to 230/400 V AC three-phase systems.

Featuring replaceable pluggable protection modules, ABB QuickSafe technology, mechanical status indication and an auxiliary signalling contact, this SPD combines robust surge protection with convenient local and remote monitoring. Its three-module DIN-rail format makes it well suited to industrial and commercial distribution boards where dependable three-phase surge protection and efficient maintenance are required.
