Siemens 8WH2 025-0AF01 Through-Type Terminal Block

The Siemens SENTRON 8WH2025-0AF01 through-type terminal block is a blue, two-tier, spring-loaded connection designed for DIN rail mounting (TH35) in control panels and industrial installations. It is a through-type terminal capable of two levels of connection with equipotential bonding between the levels, providing a compact, two‑level distribution point in a single housing. This model accepts conductors with a cross-section of 2.5 mm² and is part of Siemens’ SENTRON 8WH family of terminal blocks, specifically identified by the 8WH2025-0AF01 designation. The block is internally bridged for straightforward DIN-rail mounting (IEC 60715) and is designed for reliable, fast connections in demanding electrical environments. Electrical ratings for this unit include a 22 A operating current and a 500 V rated voltage, making it suitable for intermediate power distribution tasks within automation and control circuits. The physical footprint measures approximately 67.58 mm in height, 68 mm in length, and 45.85 mm in depth, with a net weight around 9 g per unit. With its blue through-type configuration and two-tier design, this terminal block provides a compact, dependable connection point where conducting paths need to be carried through the terminal while maintaining a common potential across levels. The 8WH2025-0AF01 is the through-type, two-tier variant for 2.5 mm² conductors within the SENTRON product lineup.
