1sna290328r1700 – d2,5/5,ll,l,v0

Why Choose the TE Connectivity 1SNA290328R1700 D2.5/5.LL.L.V0 Terminal Block?

The TE Connectivity 1SNA290328R1700, also identified as D2.5/5.LL.L.V0, is a compact double-level spring terminal block designed for high-density electrical distribution and control-panel wiring. Part of the TE Connectivity Entrelec terminal block range, it combines two connection levels within a narrow DIN-rail footprint to help maximise available panel space.

Its spring-clamp connection technology provides fast, dependable conductor termination without routine screw tightening, supporting efficient assembly and long-term connection stability. The grey thermoplastic housing is manufactured to a UL 94 V-0 flammability classification, while the terminal's modular design makes it suitable for structured wiring in industrial cabinets and automation systems.

With a nominal current rating of 24 A, rated voltage of 400 V and a width of just 5 mm, the 1SNA290328R1700 offers a practical solution for space-efficient distribution wiring where reliable two-level connectivity is required.

Key Advantages

• Double-level terminal design increases wiring density while conserving DIN-rail space.
• Spring-clamp connections support fast installation and secure conductor retention.
• 24 A rated current suitable for a wide range of industrial control and distribution circuits.
• 400 V rated voltage for low-voltage electrical installations.
• Only 5 mm wide, helping optimise crowded control-panel layouts.
• UL 94 V-0 thermoplastic insulation supports demanding industrial safety requirements.

Key Features

• TE Connectivity Entrelec D2.5/5 series terminal block.
• Two-level construction with two clamping positions per level.
• Spring connection technology on both connection levels.
• 24 A nominal current rating.
• 400 V rated operating voltage.
• Grey thermoplastic housing.
• UL 94 V-0 flammability classification.
• DIN-rail mounting on 35 mm top-hat rail.
• IP20 protection at the main terminals.

Reliable High-Density Terminal Wiring

Double-level terminal blocks allow two independent wiring levels to occupy the rail space normally associated with a single conventional terminal, making them especially useful in control cabinets where installation density is important. Spring-clamp technology maintains consistent conductor pressure and removes the need for periodic screw retightening.

The D2.5/5.LL.L.V0 is designed for modular industrial panel construction and mounts directly to standard 35 mm DIN rail. Its narrow profile, V-0 rated insulation and robust terminal design make it well suited to dependable signal, control and distribution wiring in industrial environments.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• High-density signal and control wiring.
• Machine-building electrical systems.
• Power and control distribution assemblies.
• Process-control and instrumentation panels.
