The Phoenix Contact 2906324 is a Type 2 surge protection base element from the VALVETRAB MS product range. It is designed for 3-mode protection of 2-wire signals, featuring a pass-through layout that separates field and house wires for isolation.
Key electrical specifications include a nominal voltage of 5 V AC to 48 V AC, a maximum continuous operating voltage (UC) of 60 V, and a maximum continuous operating voltage (L-PE) of 230 V. It has a rated load current of 80 A and a maximum discharge current (Imax) of 20 kA (8/20 µs). The voltage protection level (Up) for L-PE is ≤ 1.5 kV, with a response time (tA) of ≤ 25 ns.
Mechanically, the unit measures 114 mm in height, 89 mm in width, and 78 mm in depth, with a horizontal pitch of 5 divisions. It mounts via DIN rail with an additional retaining screw. The housing is constructed from PBT/PA materials and has a black color. The degree of protection is IP20 when all disconnects are closed.
This surge protection base element is suitable for operation in ambient temperatures ranging from -40 °C to 80 °C. It complies with IEC test classification II, T2, and standards EN 60664-1 and EN 61643-1. The flammability rating is V0 according to UL 94. It also features an optical, remote indicator contact for surge protection fault messages.
The nominal operating voltage (UN) for this surge protection base element is 5 V AC to 48 V AC.
The maximum continuous operating voltage (UC) is 60 V, and the maximum continuous operating voltage (L-PE) is 230 V.
The maximum discharge current (Imax) for the 2906324 is 20 kA for both general use and L-PE conditions, measured with an 8/20 µs waveform.
The voltage protection level (Up) for L-PE is a maximum of 1.5 kV.
The dimensions are 114 mm in height, 89 mm in width, and 78 mm in depth, with a horizontal pitch of 5 divisions.
The ambient operating temperature range is -40 °C to 80 °C.
It is mounted on a DIN rail with an additional retaining screw.
