Feed-Through Terminal Block 4 mm2 2 Position Screw Connection White · Phoenix Contact 3045130

What this product is for

This feed-through terminal block is used to terminate and join conductors on standard NS 35 DIN rail in control panels, machinery, and industrial electrical assemblies. It provides a screw connection on both sides for organised, serviceable field and internal wiring.

Use for

Use for panel building, marshalling circuits, machine wiring, and general-purpose conductor termination where a 2-position feed-through block is required. Commonly used where electricians need a white terminal block for circuit identification and a rated cross section of 4 mm2 with conductor range from 0.14 to 6 mm2.

Avoid for

Avoid for applications requiring a fused, disconnect, multi-level, or pluggable terminal block. Also avoid where a push-in connection system is preferred over a screw-clamp termination, or where conductor size exceeds 6 mm2.

Best for

Best for industrial control panels, OEM equipment, and automation cabinets where clear conductor routing, DIN rail mounting, and dependable screw termination are required. It is a practical choice when matching existing Phoenix Contact UT series terminal block layouts.

Installed in

Installed on NS 35/7.5 or NS 35/15 DIN rail in electrical enclosures, control cabinets, process equipment, and building automation panels. Typical use is inside protected panel environments rather than exposed field mounting.

Why this product exists

This product provides a compact, standardised way to land and pass conductors through a DIN rail terminal strip while keeping wiring accessible for testing, maintenance, and future changes. White housing can also help with circuit grouping or identification in multi-circuit assemblies.

Compared with similar products

Compared with larger feed-through blocks, this 4 mm2 class terminal block suits smaller branch and control conductors while saving rail space. Compared with push-in styles, screw connection blocks are often selected where installers want a familiar termination method and straightforward retightening during maintenance. Actual suitability depends on conductor type, ferrules, torque, enclosure design, and local electrical code.
