1sna290326r0500 – d2,5/5,llp,l,v0
TE Connectivity D2.5/5.LLP.L.V0 1SNA290326R0500 is a 5 mm wide three-level spring-clamp installation terminal block combining two feed-through circuits and protective-earth functionality with a 2.5 mm² rated cross-section and 24 A, 250 V main-circuit rating.
Why Choose the TE Connectivity D2.5/5.LLP.L.V0 1SNA290326R0500 Installation Terminal Block?
The TE Connectivity / Entrelec D2.5/5.LLP.L.V0 1SNA290326R0500 is a compact three-level spring-clamp installation terminal block designed for industrial electrical panels and TN-C-S network applications. Its multi-level configuration combines two feed-through circuits with a protective-earth circuit, allowing several wiring functions to be accommodated within a narrow DIN rail footprint.
With a rated cross-section of 2.5 mm², the D2.5/5.LLP.L.V0 supports rigid conductors from 0.14–4 mm² and flexible conductors from 0.14–2.5 mm². The main circuit is rated at 24 A and 250 V, while spring-clamp technology provides consistent contact pressure independently of installer-applied tightening torque.
The terminal has a compact 5 mm width and mounts on standard TH 35-7.5 or TH 35-15 DIN rails. Front wiring entry improves conductor accessibility, while the angled terminal design and integrated feed-through and earth functions help reduce the amount of DIN rail space required in high-density control, machinery and building-services installations.
Key Advantages
- Combines two feed-through circuits and one protective-earth circuit in a single terminal block.
- Three-level configuration supports high-density industrial wiring.
- Specially developed for TN-C-S network applications.
- Spring-clamp connection technology provides consistent conductor contact pressure.
- Compact 5 mm width helps conserve DIN rail space.
- Front wiring entry provides convenient access during installation and maintenance.
- Accepts rigid conductors up to 4 mm² and flexible conductors up to 2.5 mm².
- V0-rated polyamide insulation supports demanding industrial panel applications.
Key Features
- TE Connectivity / Entrelec installation terminal block.
- D2.5/5.LLP.L.V0 product designation.
- Three connection levels.
- Two feed-through circuits plus protective-earth functionality.
- Spring-clamp conductor termination.
- 5 mm spacing.
- Rated cross-section of 2.5 mm².
- Main-circuit rating of 24 A at 250 V.
- 4 kV rated impulse withstand voltage.
- IP20 protection at the main terminals.
- Suitable for standard 35 mm DIN rail systems.
Reliable Multi-Level Connections for Industrial Installations
The D2.5/5.LLP.L.V0 is designed to simplify installations where feed-through and protective-earth circuits must be accommodated in a compact terminal assembly. Combining three levels within a 5 mm-wide footprint can significantly reduce the DIN rail length required compared with arranging the individual circuit functions across separate conventional terminals.
Spring-clamp termination maintains conductor contact pressure independently of installer-applied tightening torque and automatically compensates for conductor settling. Together with front wiring entry and the compact angled design, this makes the 1SNA290326R0500 particularly suitable for efficient assembly, inspection and maintenance of densely wired industrial electrical systems.
Typical Applications
- TN-C-S electrical distribution networks.
- Industrial control and automation panels.
- Machine control and OEM electrical cabinets.
- Building-services electrical installations.
- High-density DIN rail terminal assemblies.
- Power and control distribution systems.
- Applications requiring combined feed-through and protective-earth connections.
