Phoenix 3003347 UK 2,5 N Feed-Through Terminal Block, Screw Connection, 2.5 mm², 800 V, 24 A, Grey

The Phoenix 3003347 UK 2,5 N feed-through terminal block stands out for its robust screw connection and compact design, offering a reliable solution for DIN rail installations. Unlike typical terminals that may compromise on conductor range, this model accommodates solid conductors from 0.2 to 4 mm² and stranded conductors from 0.2 to 2.5 mm², making it versatile for various wiring tasks. Its grey polyamide housing ensures durability and compliance with UL 94 V0 flammability standards, providing safety in demanding environments.

Highlights

• Nominal cross section: 2.5 mm² with screw connection technology
• Rated voltage 800 V and current 24 A (IEC)
• Wide conductor range: solid 0.2–4 mm², stranded 0.2–2.5 mm², AWG 24–12
• Mounts on standard DIN rails NS 35/7.5, NS 35/15, and NS 32
• Operating temperature from -60 °C to 105 °C
• Pollution degree 3 and overvoltage category III
• Approvals: IEC 60947-7-1, UL, CSA

In daily use

Installation is straightforward: strip the conductor to 8 mm, insert it into the terminal, and tighten the M3 screw with a torque of 0.5–0.6 Nm. The terminal's single position with two connections allows efficient feed-through wiring in control cabinets and distribution boxes. The grey colour blends seamlessly with standard industrial components, and the compact dimensions (width 5.2 mm, height 42.5 mm, depth 46.5 mm) save space on the rail.
