PTFIX 18X4-NS35-FE - Distribution block

Distribution block, Block with vertical alignment, nom. voltage: 800 V, nominal current: 32 A, number of connections: 18, connection method: Push-in connection, cross section: 0.2 mm2 - 6 mm2, mounting type: NS 35/7,5, NS 35/15, color: black/yellow

  • Space savings of up to 50 % on the DIN rail, thanks to transverse mounting
  • Time savings of up to 80 %, thanks to ready-to-mount blocks without manual bridging
  • Time-saving conductor connection, thanks to tool-free Push-in direct connection technology
  • Clear wiring, thanks to eleven different color variants
  • Flexible use, thanks to DIN rail mounting, direct mounting or adhesive mounting

PTFIX

The Phoenix Contact PTFIX Series comprises ready-to-use distribution blocks featuring Push-in connection technology, designed to streamline potential distribution in control cabinets and various industrial applications. These blocks facilitate quick, tool-free wiring, enhancing installation efficiency and flexibility. Key Features: Ready-to-Connect Design: PTFIX blocks are pre-assembled and maintenance-free, allowing for immediate deployment without the need for manual bridging. Push-in Connection Technology: This tool-free, direct plug-in method enables the easy insertion of solid and flexible conductors with ferrules, starting from 0.25 mm², reducing installation time. Compact and Space-Saving: The compact design of PTFIX blocks saves space in control cabinets, making them ideal for applications with limited installation areas. Versatile Mounting Options: Various adapters allow for DIN rail, direct, and adhesive mounting, providing flexibility to suit different installation requirements. Color-Coded Variants: Available in up to 11 different colors, PTFIX blocks support intuitive and safe installation by enabling clear potential assignment.

NoteWhen aligning several blocks, it is recommended to either place a DIN rail adapter underneath the connection point or a flange element between the blocks.
NoteFor versions with 6 or 7 connections, it is enough to place one DIN rail adapter centrally per block and place flange elements after every other block.
NoteWhen using the DIN rail adapter PTFIX-NS35, an aligned block must not protrude by more than a half.
