WAGO 280-901 Through Terminal Block, 2-Conductor, 2.5 mm², CAGE CLAMP, Gray

The WAGO 280-901 is a high-quality through terminal block designed for reliable and maintenance-free electrical connections. With a compact 5 mm width and 2-conductor design, it is ideal for DIN-rail mounting in control cabinets and junction boxes. The CAGE CLAMP® connection technology ensures fast, vibration-proof, and gas-tight wiring for solid and fine-stranded conductors up to 4 mm² (AWG 12). Rated for 800 V and 24 A, this gray terminal block meets stringent safety standards with approvals from VDE, UL, CSA, and major classification societies.

Advantages

• CAGE CLAMP® spring pressure connection eliminates the need for retightening, reducing maintenance.
• Compact 5 mm width saves space on the DIN rail.
• Wide conductor range (0.08–4 mm²) accommodates various wire sizes.
• High operating temperature range (-35 to +105 °C) suitable for demanding environments.
• Multiple international approvals ensure compliance worldwide.

Suitable for
