Why Choose the ABB OVR T2 3N 40-275 P TS QS Surge Protection Device?
The ABB OVR T2 3N 40-275 P TS QS, order code 2CTB803973R0500, is a pluggable Type 2 surge protection device (SPD) designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning and electrical switching events. As part of the ABB OVR QuickSafe surge protection range, it provides dependable surge protection for three-phase plus neutral electrical distribution systems.
Designed for 230/400 V AC TT and TN-S networks, this SPD uses a 3+1 protection configuration and provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA. Its 1.5 kV voltage protection level (Up) helps limit transient overvoltages reaching downstream electrical and electronic equipment.
The OVR T2 3N 40-275 P TS QS has a 275 V AC maximum continuous operating voltage and features pluggable protection cartridges, visual status indication and remote signalling auxiliary contacts. Its four-pole DIN rail format makes it suitable for integration into residential, commercial and industrial electrical distribution boards where reliable three-phase surge protection and remote status monitoring are required.
