2906390 Phoenix Contact - FLT-BK 350/1+1-FM - Type 1+2 combined lightning current and surge arrester

Phoenix Contact 2906390 (Surge Protection Device) is engineered in accordance with IEC 61643-11 and UL 1449 standards as a Type 1/2 or Type 2 surge protective device (SPD). It features high-capacity metal oxide varistors (MOV) and gas discharge tubes (GDT) capable of handling nominal discharge currents (In) of 20kA and maximum discharge currents (Imax) up to 40kA-50kA per phase.

The 2906390 offers a maximum continuous operating voltage (Uc) engineered for standard 230/400V or 120/208V IT/TN-S/TT grid topologies, maintaining a low residual voltage protection level (Up ≤ 1.5 kV) to safeguard sensitive PLCs, microcontrollers, and automation equipment from transient overvoltages.

Yes, 2906390 includes visual mechanical health indicators (green = normal, red = replace) on the pluggable protective module, along with an integrated potential-free dry contact (SPDT relay output) for remote signaling to SCADA, BMS, or PLC alarm systems.

Phoenix Contact 2906390 utilizes a modular, pluggable design allowing hot-swap replacement of degraded cartridges without interrupting supply power to the downstream load or rewiring base terminal connections, minimizing plant downtime.
