This Phoenix Contact 2905250 is a Type 2 surge protection base element, specifically designed for use with the VALVETRAB MS product range. It is intended for 3-phase power supplies that include a PEN conductor.
The base element features a maximum continuous operating voltage of 230V between L-PE and 60V between L-N. It offers a high discharge current capability with a maximum of 20 kA (8/20 µs) for both L-N and L-PE, and a nominal discharge current of 10 kA. The voltage protection level is rated at ≤ 1500V for L-PE and ≤ 700V for L-N and L+ to L-.
With a response time of ≤ 25 ns, this component ensures rapid protection. It is designed for DIN rail mounting (35 mm) and has a width of 53.4 mm, height of 90 mm, and depth of 65.5 mm. The housing is constructed from PBT/PA and has a flammability rating of UL 94 V0. The operating temperature range is -40°C to 80°C.
Additional features include optical surge protection fault messaging and a screw connection type for the protective circuit. The product is classified under IEC test classification II and EN type T2.
The maximum continuous operating voltage is 60 V for L-N and 230 V for L-PE.
The device is packed individually (1 piece per unit) in bulk packaging.
-40 °C to 80 °C.
Nominal discharge current (8/20 µs) is 10 kA and maximum discharge current is 20 kA for both L-N and L-PE paths.
The device mounts on a 35 mm DIN rail.
Voltage protection level is ≤700 V for L-N and (L+)-(L-) and ≤1500 V for L-PE and (L+/L-)-PE.
Response time is ≤25 ns.
