2CTB802345R2500 ABB OVR T2 3L 40-320 P TS U Type 2 Surge Protective Device

Why Choose the ABB OVR T2 3L 40-320 P TS U Surge Protective Device?

The ABB OVR T2 3L 40-320 P TS U is a robust Type 2 surge protective device (SPD) designed to protect three-phase delta electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning effects and switching events. Part of the ABB OVR surge protection range, this three-pole device provides coordinated protection across all three phases of a delta network.

The OVR T2 3L 40-320 P TS U provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA using the standard 8/20 µs surge-current waveform. It is designed for a 277 V AC nominal system voltage with a 320 V AC maximum continuous operating voltage (MCOV), providing dependable protection for compatible three-phase delta power systems.

Its pluggable construction allows the protection cartridges to be serviced or replaced without replacing the complete device base, while the TS remote signalling function enables external monitoring of SPD status. With three protected poles and a compact three-module DIN-rail format, the device is well suited to industrial distribution boards, switchboards and electrical control panels.
