Double Level Terminal Block 6.2 mm Width 4 mm2 Screw Connection · Phoenix Contact 3044814

What this product is for

This double-level terminal block is used for space-saving DIN rail wiring in industrial panels, machinery, and commercial control assemblies. It provides two levels and four connection points in one 6.2 mm wide housing for organised conductor termination.

Use for

Use for feed-through wiring where panel space is limited, including control cabinets, OEM machinery, process equipment, and building automation panels. It is suitable for copper conductors from 0.14 to 6 mm2, approximately 26 to 10 AWG.

Avoid for

Avoid where a different terminal style, conductor size, or connection technology is required, or where project specifications call for fused, disconnect, or spring connection terminal blocks instead of screw connection feed-through blocks.

Best for

Best for electricians and panel builders who need to increase wiring density on NS 35 DIN rail without moving to a larger enclosure. A typical buying advantage is fitting two potentials in one terminal block footprint while keeping wiring accessible for service and labelling.

Installed in

Installed on NS 35/7.5 or NS 35/15 DIN rail in industrial control panels, machine panels, plant equipment, and similar enclosed electrical assemblies. The block is 6.2 mm wide, 69.9 mm high, and 65 mm deep on NS 35/7.5 rail, approximately 2.44 in wide, 2.75 in high, and 2.56 in deep.

Why this product exists

This product exists to reduce panel crowding by combining two terminal levels in one compact body. Compared with single-level blocks, it can help improve wiring density and rail utilisation in tight layouts.

Compared with similar products

Compared with single-level feed-through terminal blocks, this double-level design saves rail space and can simplify multi-conductor routing in compact panels. Compared with push-in styles, screw connection is commonly selected where installers prefer a traditional torque-based termination method. Actual installation efficiency depends on conductor type, ferrules, spacing, and panel layout.
