Terminal Block 2 Level Feed Through 6.2 mm Width Screw Connection · Phoenix Contact 3044733
Double-level feed-through terminal block for DIN rail mounting with screw connections, 800 V nominal rating, 30 A nominal current, and 4 mm2 nominal cross section. Commonly used in control panels where higher wiring density and potential bridging help simplify marshalling and distribution.
What this product is for
This double-level feed-through terminal block is used to terminate and organise conductors on DIN rail in industrial control panels, machinery panels, and building automation assemblies. It provides two levels of connection in a 6.2 mm housing to help save rail space while maintaining clear circuit separation.
Use for
Use for control panel wiring, marshalling circuits, interposing field wiring, and applications where compact multi-level termination is needed. It is suited for NS 35/7.5 and NS 35/15 DIN rail systems and accepts conductors from 0.14 to 6 mm2 (approximately 26 to 10 AWG).
Avoid for
Avoid using this terminal block where a disconnect, fuse, or pluggable connection is required, or where the application exceeds the published voltage, current, conductor size, or temperature limits. Confirm accessory compatibility if bridging or marking is required for the assembly.
Best for
Best for electricians, panel builders, and OEMs who need compact DIN rail terminations with screw-clamp connections and the ability to streamline common potentials in dense control cabinets.
Installed in
Typically installed in industrial enclosures, OEM machinery panels, process control cabinets, and commercial automation panels. The 6.2 mm width is approximately 0.24 in, which helps when rail space is limited.
Why this product exists
This product exists to increase wiring density on DIN rail without moving to a more complex terminal system. A two-level design can reduce terminal count on the rail compared with single-level blocks in similar marshalling layouts. Actual panel layout efficiency depends on conductor routing, marking, bridging, and local code requirements.
Compared with similar products
Compared with single-level feed-through terminal blocks, this model provides more connection points in less rail space. Compared with push-in styles, the screw connection format may be preferred where installers want a traditional torque-based termination method and broad conductor compatibility.
