Ground Terminal Block 12 28 Awg 4 Conductor Double Level Spring Cage Din Rail Mount · Phoenix Contact 3036026
Protective conductor double-level terminal block for DIN rail grounding connections in control panels and machinery. Accepts 12-28 AWG conductors (0.08-4 mm2) with spring-cage terminations and mounts on NS 35/7.5 or NS 35/15 DIN rail.
What this product is for
This protective conductor terminal block is used to terminate and bond grounding conductors on DIN rail in industrial control panels, OEM machinery, and electrical assemblies. It is a double-level design that helps increase connection density while maintaining a dedicated PE grounding point.
Use for
Use for grounding and protective earth terminations where you need a green-yellow DIN rail terminal block with spring-cage connections. Commonly used with 12-28 AWG conductors, approximately 0.08-4 mm2, in panel building and machine wiring.
Avoid for
Avoid using this as a general feed-through terminal where a standard non-PE block is required. Also avoid applications outside its listed conductor range or where the panel design does not use NS 35 DIN rail.
Best for
Best for electricians and panel builders who need compact grounding distribution on DIN rail with four connection points and spring-cage wire retention. The double-level format is useful where panel space is limited.
Installed in
Typically installed in industrial enclosures, control cabinets, machinery panels, and automation assemblies on 35 mm DIN rail, approximately 1.38 in rail systems.
Why this product exists
This terminal block provides a low-resistance protective earth connection through the DIN rail while reducing panel space compared with single-level grounding blocks. Spring-cage termination is commonly chosen where vibration resistance and reduced retightening are preferred.
Compared with similar products
Compared with single-level PE terminal blocks, this double-level version increases wiring density in the same rail length. Compared with screw-clamp styles, spring-cage terminals are typically chosen for faster repeatable wiring and reduced maintenance. Actual suitability depends on conductor type, ferrules, installation method, and local electrical code.
