Why Choose the ABB OVR T2 N 80-350 P QS Surge Protection Device?
The ABB OVR T2 N 80-350 P QS, order code 2CTB803983R1900, is a pluggable Type 2 surge protection device (SPD) designed for neutral protection in low-voltage electrical installations. As part of the ABB OVR QuickSafe surge protection range, it helps protect electrical systems and connected equipment against transient overvoltages associated with indirect lightning and electrical switching events.
This single-pole neutral SPD provides a maximum discharge current (Imax) of 80 kA and a nominal discharge current (In) of 30 kA, both based on the standard 8/20 µs surge-current waveform. It also provides an impulse current capability of 2 kA with a 10/350 µs waveform and a voltage protection level (Up) of 1.4 kV.
With a 350 V AC maximum continuous operating voltage and compatibility with 230/400 V AC TT and TN-S systems, the OVR T2 N 80-350 P QS is suited to coordinated surge protection installations in industrial and commercial buildings. Its compact single-module, DIN rail-mounted and pluggable construction enables straightforward integration and maintenance within electrical distribution boards.
