Siemens 8WH2 003-0CG07 Terminal Block

Siemens 8WH2 003-0CG07 is a through-type spring-loaded terminal block from the 8WH2 series, designed for DIN-rail mounting in control panels. It has a length of 71.5 mm, a housing width of 6.2 mm and a cover width of 2.2 mm; the molded PA housing is color-coded green/yellow for protective earth (PE) connections. The block is rated for up to 52 A and supports conductors up to 10 mm² cross-section (for configurations using a plastic-sleeved end). Connection options include flexible conductors with end sleeves (0.25–4 mm² with plastic sleeve; 0.25–4 mm² without; two-wire end sleeve 0.25–6 mm²), with stripped lengths around 10–12 mm. It provides a rated impulse withstand voltage of 8 kV, pollution degree 3, and overvoltage category III. The plug gauge follows IEC 60947-1 with A4/A5, and the housing meets UL 94 V-0 flammability. This terminal block is suitable for distributing power and signals in industrial automation panels, including feeding PLCs, sensors, and actuators, and complements Siemens 8WH2 rail systems and accessories.
