Why Choose the ABB OVR T2 2L 40-320 P TS U Surge Protective Device?
The ABB OVR T2 2L 40-320 P TS U, order code 2CTB802343R2500, is a high-performance Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning events and switching surges. Part of the ABB OVR surge protection range and ABB's Surge Protection Devices product group, it is configured for split-phase electrical networks.
This SPD provides protection across two protected lines and delivers a maximum discharge current (Imax) of 40 kA with a nominal discharge current (In) of 20 kA. Its voltage protection rating is 1 kV, helping limit transient voltages before they can reach sensitive downstream electrical and electronic equipment.
Designed for 480/277 V AC split-phase systems, the OVR T2 2L 40-320 P TS U has a nominal voltage of 277 V AC ±15% and a maximum continuous operating voltage (Uc) of 320 V. Its pluggable design, DIN-rail format and signalling contact make it particularly suitable for distribution boards and control panels where high-capacity surge protection and convenient status monitoring are required.
