3-Pin Dedicated High-power Power Transmission: Adopting a standard 3-pin full-power channel layout, this connector is specially designed for high-power power supply scenarios without signal interference. The balanced three-phase pin arrangement adapts to mainstream industrial low-voltage power circuits, ensuring stable and pure power transmission and avoiding current imbalance and circuit disorder for heavy-duty equipment power supply.
600V/50A Super High Load-bearing Performance: Rated at 600V high voltage and 50A large current, it delivers superior electrical load capacity than ordinary connectors. Built with thickened and widened high-conductivity copper terminals, it features large conductive area and low power loss. It maintains stable operation without overheating or attenuation under long-term full load, ideal for heavy-duty industrial and new energy equipment power supply.
Premium Modified PA66 Flame-retardant Housing: Integrally injection-molded with high-quality modified PA66 nylon material, the housing features high strength, high toughness and high rigidity. With original UL94 V0 flame retardancy, excellent insulation, impact resistance and tensile resistance, it effectively resists mechanical damage and ensures long-term industrial service stability.
Tool-free Quick Lock Self-locking Structure: Featured with thread-free professional quick-lock design, the male and female connectors can be automatically and tightly locked by simple pushing. The anti-loosening and anti-drop structure provides excellent shock resistance. Press-to-release design supports fast manual assembly and disassembly without tools, greatly improving construction and maintenance efficiency for heavy-duty circuits.
IP67 Industrial Waterproof & Dustproof Protection: Equipped with thickened high-elastic custom sealing ring and seamless quick-lock fitting structure, the fully enclosed connector reaches IP67 protection grade. It effectively resists industrial dust, water immersion, moisture and oil corrosion, preventing contact oxidation, short circuit and electric leakage under heavy-load working conditions for all-weather stable operation.
Standard M25 Specification with Upgraded Safety Insulation: Adopting M25 large-size standard specification with widened pin spacing, it greatly improves high-voltage insulation performance and avoids creepage and breakdown risks under 600V high voltage. The large cavity provides sufficient heat dissipation space to reduce operating temperature and enhance overall operational safety and stability.

Frequently Asked Questions
Q: Are you a factory or trading company?
A: We are a factory located in Ulinkcon Industrial Park, Bao'an District, Shenzhen, China.
Q: What is rated Current?
A: Rated current, also known as operating current. With the rated voltage, as in the case below the rated current, air plug in general can work properly. Plug in the aviation design process, through the thermal design of the connector to meet the requirements of the rated current, because in contact with on a current flow out of date, due to conductor resistance and contact resistance, contact on will be heat. When the heat exceeds a certain limit, the plug will damage the insulation and the formation of air exposure on the surface of the coating to soften, resulting in failure.
Q: How can I get samples?
A: We are pleased to offer samples, with freight costs covered by the customer. Please provide your courier account number and detailed address, and we will dispatch samples immediately.
