Double-Level Terminal Block for Protective Conductor Phoenix Contact 3211854

Feed-Through Terminal Block 4 mm2 Nominal Push In Connection · Phoenix Contact 3211854

SKU: PHO-3211854

Protective conductor double-level terminal block for DIN rail grounding circuits with push-in connection and 4 mm2 nominal conductor size. Accepts 0.2 to 6 mm2 conductors (24 to 10 AWG) and is commonly used in control panels, machinery, and industrial assemblies where space-saving PE termination is required.

What this product is for

This protective conductor double-level terminal block is used to terminate and distribute PE grounding conductors on standard DIN rail assemblies in industrial and commercial control panels.

Use for

Use for grounding circuits in panelboards, machinery, process equipment, and OEM control assemblies. It is suited to applications needing a compact two-level PE terminal with push-in wiring and DIN rail grounding contact.

Avoid for

Avoid using this as a general feed-through terminal where a standard insulated pass-through block is required. Confirm conductor range, rail type, and accessory compatibility before ordering for retrofit work.

Best for

Best for electricians and panel builders who need a compact green-yellow PE terminal block with fast push-in termination, four connection points, and mounting on NS 35/7.5 or NS 35/15 DIN rail.

Installed in

Typically installed in industrial control panels, machine cabinets, plant equipment, and commercial electrical enclosures using 35 mm DIN rail.

Why this product exists

This terminal block provides a low-resistance protective conductor connection through the DIN rail while reducing wiring space by using a double-level design. Push-in termination helps speed assembly and supports consistent panel wiring practices.

Compared with similar products

Compared with single-level PE terminal blocks, this double-level design saves rail space by providing two levels and four total connections in one block. Compared with screw-type terminals, push-in connection can reduce installation time for solid conductors and ferruled stranded conductors.
