1sna110418r2500 – d4/6,a,llp

Why Choose the TE Connectivity D4/6.A.LLP 1SNA110418R2500 Installation Terminal Block?

The TE Connectivity D4/6.A.LLP 1SNA110418R2500 is a compact three-level screw clamp installation terminal block designed for distribution boxes, industrial control panels and structured electrical installations. Part of the established ENTRELEC SNA screw-clamp terminal range, it combines multiple connection levels within a narrow DIN rail footprint to support efficient and organised panel wiring.

The D4/6.A.LLP features grey and green-yellow identification and incorporates a protective-earth function for installation and distribution applications. Its proven screw clamp connection system accepts conductors in the 18–12 AWG UL range, while the terminal carries a 20 A UL current rating and a 30 A main-circuit rated current.

With a width of only 6 mm and overall dimensions of 90 × 6 × 44 mm, the 1SNA110418R2500 provides high connection density while remaining straightforward to install and service. It mounts on G32, TH35-7.5 and TH35-15 DIN rails and offers IP20 protection at the main terminals for dependable use inside electrical enclosures.
