Phoenix PTTB 1,5/S Κλέμα σειράς διπλού επιπέδου, Push-in, 1,5 mm², γκρι

Double-level terminal block with push-in connection technology, engineered for high-density wiring in control cabinets and distribution boxes. This Phoenix PTTB 1,5/S offers four push-in termination points across two levels, enabling space-saving signal and power distribution up to 17.5 A and 500 V. The tool-free push-in design accepts solid and stranded conductors from 0.14 to 1.5 mm², dramatically reducing installation time compared to screw terminals.

Advantages

Two-level design doubles wiring density on the DIN rail, saving valuable cabinet space. Push-in terminations allow direct insertion of rigid conductors or flexible conductors with ferrules—no tools required. The grey polyamide housing is halogen-free and UL 94 V0 rated, ensuring fire safety and durability in harsh industrial environments. Clear marking areas on each level simplify circuit identification and maintenance.

Suitable for

• Control panel builders needing compact, high-density terminal strips
