LLT Premium Quality M45 600V High Current 80A 3 Pin 4 Pin Waterproof Screw Assembly Connector

Model: M45-3pin 80A Waterproof Assembly Circular Connector Structure: Straight cable-to-cable in-line assembly; panel mount bulkhead version optional Core positioning: Three large-current power pins, dedicated for three-phase power or positive/negative + ground power connection Core Product Advantages 1. 80A Super High Current Capacity Thickened large-diameter brass contacts with heavy gold plating, contact resistance ≤8mΩ. Sustains continuous 80A load without overheating or voltage drop, perfectly matched for high-capacity battery packs, inverters and large industrial power supply systems, rated voltage up to 600V DC/AC. 2. IP68 Full Waterproof & Dustproof Protection Three-tier silicone rubber sealing structure: cable inlet clamping seal, mating surface compression gasket and integrated shell seal. Resists full water immersion, rain, mud, dust, oil mist and chemical vapor, suitable for outdoor, flood-prone and damp workshop working conditions. 3. Heavy-Duty Anti-Aging Shell Material Housing: PA66+30% glass fiber reinforced nylon, UL94-V0 flame retardant, UV-resistant, shockproof and anti-cracking. Stable performance under extreme temperature range of -40℃ ~ +105℃, long service life for outdoor all-year operation. 4. Easy On-Site Field Assembly Screw-type terminal wiring structure, no special crimping tools required for fast wiring and maintenance. Adjustable cable gland fits wire outer diameter 13–28mm, compatible with large cross-section power cables. Rotatable threaded locking ring tightly locks plug and socket to avoid loose connection under strong vibration of construction machinery and energy storage equipment. 5. Safe & Durable Mechanical Performance ≥3,000 stable plug-unplug mating cycles; unique anti-reverse insertion keyway prevents wrong mating and short-circuit risks. High insulation resistance ≥1000MΩ (DC500V), withstand 1500V dielectric voltage for 1 minute to eliminate electric leakage hazards.
