Phoenix 3210600 PTTBS 2,5-TWIN dubbeldek-rijgklem, push-in, 4 aansluitingen, 2,5 mm², 500 V, 22 A, grijs

Double-level terminal block with push-in connection technology, offering four connections in a compact design for demanding industrial applications. Its dual-level structure saves space on the DIN rail while maintaining high wiring density.

Advantages

The push-in connection system enables tool-free wiring of solid and stranded conductors with ferrules, reducing installation time by up to 50% compared to screw connections. The double-level design doubles the number of connection points per unit length, optimizing panel space. The PA insulating material provides excellent mechanical strength and is halogen-free, meeting UL 94 V0 flammability requirements. The terminal is rated for 500 V and 22 A, suitable for a wide range of control and power distribution tasks.

Suitable for

• Control cabinet wiring in industrial automation
• Power distribution in machinery and equipment
• Building installation with DIN rail mounting
• Applications requiring high wiring density and tool-free connections
