Ground Terminal Block 4 mm2 Spring Cage Din Rail Mount · Phoenix Contact 3031380
Phoenix Contact 3031380 is a spring-cage ground terminal block for DIN rail mounting in control panels and distribution assemblies. It provides 2 connections, accepts 0.08 to 6 mm2 conductors (approximately 28-10 AWG), and is sized for 35 mm DIN rail.
What this product is for
This ground terminal block is used to terminate and bond protective conductor wiring on 35 mm DIN rail in control panels, machinery panels, and electrical distribution assemblies. The spring-cage connection supports fast, consistent conductor termination for panel wiring.
Use for
Use for PE/ground terminations, panel grounding points, OEM control cabinets, and industrial or commercial assemblies where a DIN rail mounted protective conductor terminal is required. Commonly used where quick wiring and secure rail bonding are important.
Avoid for
Avoid using this as a standard feed-through terminal where a non-grounded insulated terminal block is required. Also avoid applications outside the listed conductor range or where the mounting rail does not match 35 mm DIN rail profiles.
Best for
Best for electricians and panel builders standardizing on Phoenix Contact ST series spring-cage terminal blocks and needing a compact PE terminal with direct DIN rail grounding.
Installed in
Typically installed in industrial control panels, MCC-related auxiliary sections, OEM equipment panels, building automation panels, and commercial electrical enclosures. Mounts on NS 35/7.5 or NS 35/15 DIN rail, both based on 35 mm rail width (approximately 1.38 in).
Why this product exists
This terminal block provides a dedicated protective conductor termination point with low-resistance connection to ground potential through the DIN rail. Spring-cage technology helps speed installation and maintain clamping force without screw retorquing during normal service.
Compared with similar products
Compared with standard feed-through terminal blocks, this PE terminal is specifically intended for grounding and uses the green-yellow housing for quick identification. Compared with screw-clamp styles, spring-cage terminals are commonly chosen for faster repetitive panel wiring and consistent conductor retention. Actual suitability depends on conductor type, enclosure design, and local electrical code.
