PL 325-XX-00 Product Diagram
Featuring a 12.7mm extra-wide center space (for ultra-thick power cables) and a 1000V AC/DC, 325A rating, it operates across a temperature range of -40℃ to 125℃—ideal for heavy-duty scenarios like metallurgy equipment, large-scale energy storage plants, and high-voltage industrial motors. Constructed with ceramic-enhanced PA66 insulation (40% glass fiber + ceramic additives) and oxygen-free copper (OFC) terminals, it minimizes power loss and heat generation, while its 10,000V surge voltage resistance protects against utility-grade power spikes. With a wire range of 4–4/0 AWG (for ultra-thick cables) and fixed 2P/3P configurations, the PS-325-XX-00 is tailored for critical infrastructure where failure is not an option—delivering reliability in the harshest industrial conditions.
Ceramic-Enhanced PA66 Insulation: 40% glass fiber + ceramic-reinforced PA66 thermoplastic withstands temperatures up to 125℃ and resists industrial chemicals (oils, solvents, molten metal splatters). UL94 V-0 flame retardancy meets utility safety standards, and the 25mm width provides ample pole spacing to prevent arcing.
Oxygen-Free Copper (OFC) Terminals: 99.99% OFC terminals offer ultra-low resistance (＜0.0003Ω per terminal), minimizing heat generation at 325A current. OFC resists corrosion and oxidation better than standard copper, ensuring long-term performance in high-humidity or chemical-exposed environments.
Inconel-Coated Screws: M10 Inconel-coated steel screws require 40–45 lbf·in of torque for wire clamping. Inconel (a nickel-chromium alloy) resists extreme heat (up to 1200℃) and corrosion, making it suitable for metallurgy or foundry applications.
325A/1000V Rating: Handles extreme loads like 690V AC metallurgy induction furnaces (300A), 800V DC large-scale BESS systems (325A), or 480V AC high-voltage industrial motors (280A). The 1000V rating is compatible with medium-voltage utility grids.
Surge Protection: Withstands 10,000V transient spikes, shielding critical equipment (e.g., furnace controllers, BESS inverters) from utility grid faults or lightning strikes—common in outdoor infrastructure.
Heat Management: The terminal’s large OFC surface area (2x larger than standard high-current terminals) and heat-dissipating insulation design promote passive cooling, preventing overheating during 24/7 operation.
Wire Compatibility: Accepts 4–4/0 AWG wires, covering ultra-thick power cables (4/0 AWG for BESS systems) and thick control wires (4 AWG for furnace sensors). The clamping mechanism features a 25mm opening to fit stranded 4/0 AWG wires, common in ultra-high-current systems.
Recommended Stripping Length: 20mm for 4–2 AWG wires and 25mm for 4/0 AWG wires—ensuring full contact with OFC terminals, eliminating resistance hotspots.
Secure Mounting: Fits 8.0mm steel panel holes with M8 Inconel-coated mounting screws (included). Anti-vibration gaskets on the base prevent shifting in heavy machinery (e.g., mining crushers).
Available in fixed 2P (25.4mm total length) and 3P (38.1mm total length) setups—optimized for 2-wire DC (BESS) and 3-phase AC (industrial motors) systems. No modular assembly is needed, reducing installation time in high-pressure industrial settings.
Induction Furnaces: Connects power wires for medium-frequency induction furnaces (e.g., 690V AC/300A) used in steel or aluminum melting. Ceramic-enhanced insulation resists molten metal splatters, while OFC terminals handle high currents without overheating.
Rolling Mills: Used in rolling mill motor power lines (e.g., 480V AC/280A) and temperature sensor wiring. The 125℃ temperature range withstands mill heat, and Inconel screws resist mill dust and oil.
Utility-Scale BESS: Integrates into 800V DC BESS systems for grid stabilization or renewable energy storage. The 325A rating handles battery charging/discharging cycles, and 1000V compatibility matches BESS inverter voltages.
Hydrogen Fuel Cells: Connects power wires between large fuel cell stacks (e.g., 600V DC/300A) and grid inverters. OFC terminals ensure efficient energy transfer, while surge protection safeguards against fuel cell power fluctuations.
Mining Crushers & Conveyors: Powers large mining crusher motors (e.g., 480V AC/325A) and long-distance conveyor systems. Anti-vibration gaskets prevent connection loosening, and ceramic insulation resists mining dust and moisture.
Shipboard Power Systems: Used in large cargo ship propulsion motor auxiliaries (e.g., 690V AC/290A). The corrosion-resistant design handles saltwater exposure, and 10,000V surge protection safeguards against marine lightning strikes.
OFC has 5% higher conductivity than standard copper and contains fewer impurities, reducing resistance and heat generation at ultra-high currents. Its low oxygen content also prevents oxidation in humid or chemical environments—critical for long-term reliability in utility-scale systems (e.g., BESS plants with 10+ year lifespans).
Yes. Its ceramic-enhanced insulation and Inconel screws resist rain, snow, and saltwater (for shipboard use). For fully outdoor installations (e.g., outdoor BESS enclosures), pair it with an IP67-rated enclosure to protect against direct water exposure and dust.
It operates reliably at up to 125℃ (257℉)—suitable for near-furnace or high-heat industrial environments. For temperatures exceeding 125℃ (e.g., foundry near-melting zones), add a water-cooled jacket to the enclosure to maintain terminal temperature within safe limits.
Inconel offers superior heat resistance (up to 1200℃ vs. stainless steel’s 800℃) and corrosion resistance, making it ideal for metallurgy or foundry applications where screws may be exposed to molten metal splatters or harsh chemicals. Stainless steel would degrade quickly in these environments.
