LLT Large Power M45 4pin Screw Wire 80A 600V 2pin 3pin 4pin Electrical Assembly Connector

Model: M45-4pin 80A Waterproof Assembly Circular Connector Available types: In-line cable-to-cable coupler, panel mount bulkhead receptacle Layout: 4 independent high-current pins, flexible for 3-phase power + ground or dual power + dual signal layout Core Product Advantages 1. Ultra-High 80A Single-Pin Current Capacity Oversized solid brass contacts with thick gold plating, contact resistance ≤8mΩ. Stable continuous 80A loading with minimal heat generation and voltage drop, ideal for high-power energy storage, inverters and large outdoor power equipment. Rated voltage reaches 600V for both AC and DC circuits. 2. IP68 Full Waterproof & Dustproof Protection Three-layer silicone rubber sealing system: cable clamping seal, mating face compression gasket and integrated shell sealing structure. Fully blocks water immersion, rain, mud, dust, oil mist and weak chemical vapor, suitable for outdoor, flood-prone, damp workshop and marine working environments. 3. Rugged Flame-Retardant Shell Material Housing adopts PA66+30% glass fiber reinforced nylon, UL94-V0 flame retardant grade, UV-resistant, shockproof, anti-aging and crack-proof. Stable electrical performance under extreme temperature range of -40℃ ~ +105℃, long service life for year-round outdoor operation. 4. Convenient On-Site Assembly Structure Screw-type terminal wiring requires no professional crimp tools for fast wiring, maintenance and replacement. Adjustable cable gland fits wire outer diameter 12–28mm, compatible with large cross-section power cables. Rotatable coarse thread locking ring tightly locks plug and socket to avoid disconnection caused by pulling or mechanical vibration. 5. Safe & Durable Mechanical & Electrical Performance ≥3000 reliable plug-unplug mating cycles; unique anti-reverse insertion keyway eliminates mis-mating and short-circuit risks. Insulation resistance ≥1000MΩ (DC500V), withstand 1500V dielectric voltage for 1 minute to prevent electric leakage.
