Protective Terminal Block 20 10 Awg Double Level Spring Connection · Phoenix Contact 3036039
Double-level protective conductor terminal block for DIN rail grounding, with spring connection and direct rail contact. Supports 20-10 AWG conductors and is commonly used in control panels where a compact PE termination point is needed.
What this product is for
This protective conductor terminal block is used to terminate and bond grounding conductors on DIN rail in control panels, machinery, and industrial enclosures. It provides a low-resistance connection to ground potential through direct contact with the top-hat rail.
Use for
Use for PE grounding points in panel boards, OEM equipment, and industrial control assemblies. Suitable for conductor sizes from 20 to 10 AWG under CSA approvals, with Phoenix Contact spring connection technology for secure wiring.
Avoid for
Avoid using this as a general feed-through terminal where a non-grounded circuit connection is required. Also avoid applications that need specifications not confirmed here, such as exact width, stripping length, or current rating, unless verified from the project documentation.
Best for
Best for electricians and panel builders who need a compact double-level PE terminal block with direct DIN rail grounding and compatibility with CLIPLINE complete accessories.
Installed in
Typically installed on standard top-hat DIN rail inside control cabinets, industrial panels, commercial equipment, and automation enclosures.
Why this product exists
It simplifies protective conductor termination by grounding directly through the DIN rail, reducing extra wiring effort and helping create orderly, high-density panel layouts.
Compared with similar products
Compared with single-level PE terminals, this double-level design helps save rail space while still providing dedicated grounding termination points. Spring connection style is commonly chosen where consistent clamping force and vibration resistance are preferred over screw termination.
