The Phoenix Contact 2906326 is a Type 2 (T2) surge protection device designed for industrial and commercial power systems. It provides coordinated protection against transient overvoltages on 3-position (L+, L-, PE) circuits with a nominal voltage range of 5 V AC to 48 V AC.
Key electrical specifications include a maximum continuous operating voltage of 60 V, a nominal discharge current of 10 kA (8/20 µs), and a maximum discharge current of 20 kA (8/20 µs) for L-PE paths. The device offers a voltage protection level of ≤ 1.5 kV and a fast response time of ≤ 25 ns. It is rated for a load current of 80 A and features a residual current of ≤ 5 µA.
The device is housed in a PBT/PA enclosure with a V0 flammability rating per UL 94. It mounts on a DIN rail with an additional retaining screw and has M5 screw terminals with a stripping length of 16 mm. Dimensions are 114 mm height, 124 mm width, and 78 mm depth. Fault indication is provided via an optical and remote indicator contact.
The operating temperature range is -40 °C to 80 °C.
The nominal voltage range is 5 V AC to 48 V AC.
The maximum discharge current (8/20 µs) for L-PE is 20 kA.
The response time is ≤ 25 ns.
It is mounted on a DIN rail with an additional retaining screw.
The degree of protection is IP20.
