The TE Connectivity / ENTRELEC D4/8.D2.P.SF, manufacturer part number 1SNA400270R2000, 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 SNA series, it combines fuse functionality with screw-clamp conductor termination in an 8 mm-wide terminal assembly.
The D4/8.D2.P.SF provides two connection levels, three circuits and six connection positions, allowing multiple functions to be incorporated into a compact DIN rail footprint. Its lever-operated disconnect arrangement provides convenient access to the fused circuit, making the terminal suitable for applications where circuit protection, isolation and organised high-density wiring are required.
Rated at 6.3 A and 300 V under IEC, UL and CSA specifications, the 1SNA400270R2000 also provides an IEC impulse withstand voltage of 6,000 V. The terminal accepts 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 wide operating temperature range support dependable industrial installation.
Fuse terminal blocks combine circuit protection and conductor termination within the same DIN rail assembly, reducing the need for separate fuse holders and helping panel builders create organised control systems. The D4/8.D2.P.SF extends this concept with a two-level arrangement that accommodates three circuits and six connection positions within an 8 mm-wide footprint.
The lever-operated disconnect function provides convenient circuit separation for maintenance and fault finding, while screw-terminal connections provide secure and serviceable conductor termination. With its 6.3 A and 300 V ratings, IP20 protection and wide operating temperature range, the D4/8.D2.P.SF is particularly suited to protected signal circuits in industrial automation and machinery applications.
