Why Choose the TE Connectivity D4/8.D2.P.SFL Double-Level Fuse Terminal Block?

The TE Connectivity / ENTRELEC D4/8.D2.P.SFL, manufacturer part number 1SNA400271R1500, is a compact double-level fuse DIN rail terminal block designed for protected signal and control circuits in industrial automation, machinery and electrical panels. Part of the established ENTRELEC ADO System range, it combines fuse functionality, lever disconnection and screw-terminal conductor termination within an 8 mm-wide modular terminal.

The D4/8.D2.P.SFL provides two levels, three circuits and six connection positions, allowing multiple wiring functions to be accommodated within a compact DIN rail footprint. Its lever-operated disconnect mechanism provides convenient circuit isolation for testing, commissioning and maintenance, while the integrated fuse function enables individual signal circuits to be protected within the terminal assembly.

With a rated current of 6.3 A, rated voltage of 300 V and IEC impulse withstand voltage of 6,000 V, the 1SNA400271R1500 is engineered for dependable industrial signal wiring. It accommodates flexible conductors from 0.5–4 mm² and rigid stranded conductors from 0.5–6 mm², while its polyamide 6.6 housing, IP20 protection and -55–110 °C operating temperature range support demanding control-panel environments.

Key Advantages

  • Combines fuse protection and terminal connection within a compact DIN rail component.
  • Double-level construction increases wiring density in industrial control cabinets.
  • Provides three circuits and six connection positions.
  • 6.3 A rated current under IEC, UL and CSA specifications.
  • 300 V rated voltage for industrial signal and control circuits.
  • Lever-operated disconnect mechanism simplifies circuit isolation and maintenance.
  • Compact 8 mm width helps conserve valuable DIN rail space.
  • Compatible with standard TH 35-7.5 and TH 35-15 DIN rails.

Compact Fuse Protection for High-Density Signal Wiring

Fuse terminal blocks combine conductor termination and circuit protection within the same DIN rail assembly, helping reduce the need for separate panel-mounted fuse holders. The D4/8.D2.P.SFL extends this concept with a double-level arrangement incorporating three circuits and six connection positions within an 8 mm-wide footprint, making efficient use of space in densely populated industrial cabinets.

Its lever-operated disconnect mechanism allows the relevant circuit to be conveniently isolated during commissioning, measurement, maintenance or fault finding. Combined with screw-terminal conductor connections, IP20 protection and a wide operating temperature range, the D4/8.D2.P.SFL provides a practical solution for protected signal circuits in machinery, process control and industrial automation systems.

Typical Applications

  • Fused industrial signal circuits.
  • PLC input and output circuit protection.
  • Industrial automation and control panels.
  • Machine building and OEM electrical systems.
  • Instrumentation and process control circuits.
  • Factory automation and production machinery.
  • High-density protected control wiring.
  • Circuits requiring convenient fuse isolation and maintenance access.
