lugs su25-6

Description

Item Description: SC25-6 (SU25-6) Tinned Copper Cable Lug The SC25-6 (also referred to as SU25-6 by certain electrical manufacturers) is a heavy-duty, seamless tubular terminal lug designed to create a reliable, low-resistance electrical connection for mid-sized power cables. Manufactured from high-purity electrical copper, these lugs are treated with an electro-tinned finish. This tinned copper coating protects the joint against oxidation, rust, and galvanic corrosion—making it excellent for high-humidity, automotive, marine, and industrial environments. Decoding the “25-6” Specification: 25: Indicates that the internal barrel opening is precision-sized for a wire cross-sectional area of 25 mm 2 (which is equivalent to 4 AWG American Wire Gauge cabling). 6: Indicates that the flat ring eyelet features a hole sized for an M6 screw or stud (with an opening diameter of approximately 6.2 mm or 1/4 inch). Compatible Mechanisms & Installation Tools Because the SC25-6 manages substantial current capacities, it must interface with specific mechanical compression tools and electrical termination nodes to function safely: 1. Mechanical Installation Tools A 4 AWG (25 mm 2 ) cable cannot be reliably attached using standard pliers. It requires dedicated compression mechanisms to ensure a “cold-weld” joint that won’t slip loose under thermal stress: Mechanical Crimp Tools: Heavy-duty, long-handled crimping pliers equipped with a rotating or interchangeable die set labeled for 25 mm 2 or 4 AWG. Hydraulic Cable Crimpers: Small hand-pumped hydraulic units capable of applying multiple tons of pressure for a perfectly uniform hexagonal or point-press crimp profile. 2. Compatible Wire & Cable Mechanisms The sleeve is physically calibrated to clamp tightly onto standard multi-strand or highly flexible copper conductors: Stranded Copper Power Cables: Perfectly fits 25 mm 2 / 4 AWG battery cables, welding leads, secondary distribution mains, and heavy equipment grounding straps. 3. Compatible Connection Nodes (The M6 Stud) The flat ring eyelet is engineered to slide perfectly onto M6 (6 mm Thread Diameter) hardware assemblies, which are standard across various power distribution setups: Power Inverters & Solar Charge Controllers: Connects the primary 12V/24V DC input or output terminals to a battery bank system. Battery Terminals & Isolators: Fits the M6 screw studs commonly found on lithium iron phosphate (LiFePO4) batteries, marine dual-battery selectors, and automotive starter systems. Electrical Busbars & Panels: Direct fit for grounding bars, distribution bus blocks, and commercial fuse holders (such as ANL or MIDI fuse blocks). Industrial Contactors & Relays: Fits mid-sized automated switching relays, terminal blocks, and motor starter nodes.
