Phoenix 3210604 PTTBS 2,5-TWIN/2P Double-Level Feed-Through Terminal Block

Double-level feed-through terminal block with push-in connection technology, offering four connections across two levels for compact and efficient wiring in control cabinets and distribution boxes. Its 2.5 mm² nominal cross-section and 22 A current rating make it ideal for dense signal and power distribution in industrial applications.

Advantages

The push-in connection system allows for tool-free insertion of solid conductors and conductors with ferrules, significantly reducing wiring time. The double-level design doubles the connection density per unit length on the DIN rail, saving valuable cabinet space. The terminal block is made of flame-retardant polyamide (UL 94 V0) and supports a wide operating temperature range from -60 °C to 105 °C, ensuring reliability in harsh environments. It is approved by VDE, UL, cUL, CSA, and EAC, meeting international standards.

Suitable for

• Control cabinet wiring in industrial automation
• Distribution boxes in building installation
• Signal and power distribution in machinery
• Applications requiring high-density wiring on DIN rails
• Use with solid, stranded, and ferruled conductors from 0.14 mm² to 4 mm²
