The TE Connectivity D4/6.LL 1SNA110442R2500 is a compact two-level screw clamp installation terminal block designed for reliable and space-efficient electrical connections in distribution boards, control panels and industrial installations. Part of the established ENTRELEC installation terminal range, this grey DIN rail terminal provides two separate electrical potentials within a narrow 6 mm-wide format.
The D4/6.LL uses proven screw clamp connection technology to provide secure mechanical and electrical conductor termination. Its two-level construction increases wiring density by arranging separate connections vertically, helping installers reduce the DIN rail space required in densely populated electrical enclosures while maintaining straightforward access for installation and maintenance.
With an IEC rated voltage of 400 V, an IEC rated current of 30 A and a 4 mm² rated cross-section, the 1SNA110442R2500 provides dependable performance for professional installation wiring. It accepts rigid and flexible conductors from 0.2–4 mm² and can be mounted on G32, TH35-7.5 and TH35-15 DIN rails.
Multi-level installation terminal blocks such as the TE Connectivity D4/6.LL provide an efficient method of organising separate electrical circuits within distribution boards and control cabinets. The two-level construction accommodates two separate potentials vertically within a compact 6 mm-wide terminal, helping increase wiring density without sacrificing convenient conductor access.
The D4/6.LL combines established screw clamp termination technology with a compact DIN rail design for dependable professional installations. Its 4 mm² conductor capacity, high impulse withstand capability and compatibility with several common DIN rail formats make it a versatile choice for electrical distribution, machinery and control panel wiring.
